Serial-to-Ethernet Converters with CompactLogix
mlb0066 posted a topic in Allen Bradley / Rockwell Automation
Hi Everyone, I'm trying to use a Weidmueller IE-CS-2TX-1RS232/485 as a communication device with a SICK CLV503-0000 barcode scanner, taking the RS232 signal from the scanner, then converting it to Ethernet/IP and transmitting it to my controller, which is a CompactLogix L18ERM-BB1B PLC. I was wondering if anyone could find the information to set up the communications in Studio 5000. I'm not having any trouble with the converter receiving the signal from the scanner, but I don't know how to set up the module in Studio 5000 to get the data from the converter, and I can't find that information anywhere on the Weidmueller website. Thanks in advance for your help.- 4 replies

5069-Serial-DF1 replacing PLC5 Channel 0 DF1
Manfred posted a topic in Allen Bradley / Rockwell Automation
Hello, I would like to replace PLC5/40 CH0 communication to an existing Microcontrollersystem with Compact Logix 5069 - Serial. In the Compact Logix I am using a MSG instruction ( PLC5 Typed write ), The Communication works like expected. Compact Logix is receiving Data, but only N100[0] gets updated. The Microcontrollersystem shall send Data to N100, Length 22 Words, Receive Area begins with 0. I have attached an Excel sheet which shows the Data handling. It was not possible for me to Read Data from Local:1:I1.DF1Modem.RxData also Local:1:I1.DF1Modem.RxDataLength does not get changed. It looks like the receiving Data from Microcontroller are direct send to N100. ( most likely following a MSG Write Instruction from Microcontrollersystem ). In PLC5 world an Integer File, like N100, was defined as N100:0, N100:1 etc. there is a difference now within CMPLX, an Integer File looks now: N100[0], N100[1], etc. big question: Does it matter? How can I catch incoming Data to the Serial Modul? PLC5_2_MCS 20240702.docx PLC5 zu LCT3 20240702.docx -

I've setup an Omron NX102 PLC with two CIF105 cards communicating with about 40 MX2 VSD's (20 on each card). Generally it works pretty well. I used the attached document to set up the devices. The links on the document to the examples don't work, so I'm unsure if I missed anything. My problem is that every day, sometimes multiple times a day the communication seems to die. i.e I either loose the output to the VSD and nothing will run. Or it all runs but I loose the feedback, as in I get no running signal even though the drives are running causing a fault in my program. I'm at a bit of a loss as to what might be causing the issue. To resolve it, I put the PLC into program mode and back into run mode and everything is happy again. Has anyone had a similar issue or offer any advise? MX2_Control_Serial.pdf

Omron CQM1H - NOS purchase - ERR/ALM LED On - Program Transfer Problems
JEJump posted a topic in CX-Programmer
Hi Everyone,I have a customer that needs a CQM1H (CPU51) replaced. They purchased the processor new-old-stock from a source they found online. It arrived in the original packaging and had the safety label around the top of the unit, so it seems that it is as advertised and no need to suspect that it would have problems. I purchased secondhand, a power supply to attach to it and program it from the bench instead of in the machine. The customer also provided me with an SD card containing the project file(s) for the machine. I am able to load the project in CX-ONE (running on Win 7) just fine. My computer has a native serial port (COM1) and I built a programming cable to work with the DB9 peripheral port according to a diagram I found online.The processor powers up right away with the ERR/ALM continuously on. No other LEDs came on initially, and after a bit of playing around with communications settings, I finally landed the right protocol and my computer seemed to identify the processor correctly. I compiled the source and attempted a transfer to the PLC. I got some failed message (or maybe messages) at the end of the transfer. It did seem to send all of the binary code, it just ended with an error message that I unfortunately didn't write down or grab a screenshot.Anyway, what I have now is a PLC processor with the ERR/ALM LED on always, I've never seen it in RUN mode, and now after the programming attempt, I'm seeing the COMM LED strobing at about a .5sec frequency (with or without a cable attached to the peripheral port), AND I cannot get CX-Programmer to again acknowledge the processor anymore. I'd like to reset this back to the way it arrived to me, but can't figure out how to make that happen offline. The DIP switches don't seem to cause that effect. I should say also that the DIP switch settings are all OFF except 3 and 7.Any help is much appreciated!Thanks,John- 3 replies

I am trying to connect a Panel PC (Bartec RS-422) and an Omron PLC (CJ2H RS-232) I am using a Kinematics 2199 RS232 to RS422 converter. Results: Testing software Multiway v9.5 1) Using a usb to rs-232 cable on another PC - I am able to send and receive a hostlink commands between the panel rs-422 converter and the PC rs-232. commands come through correctly 2) Using the PC to connect to the PLC - If I connect directly to the PLC using the usb to serial cable and a short adapter I made to map the Omron PLC pin out 2-2,3-3, 5-9, I can send and receive hostlink commands to the PLC. Everything works as expected 3) Using the Panel and the USB Cable - If I connect the usb converter to the Panel I am also able to communicate with the PLC 4) using the RS-422 port on the Panel - If I connect the panel RS-422 port and converter and then connect to the PLC. I can only send commands; I cannot get any responses come through from the PLC. My converter box has LEDs on the RX and TX channels and I can see the PLC tries to send something. But something must be corrupted as multiway does not show and response. I have tried a bunch of things but I am at a loss on how to diagnose this issue. Since I can get the two PCs talking to each other sending and receiving, I can rule out any wiring issue between the converter box and Panel. Since I can plug the USB into the Panel and get it to work correctly, I can rule out any operating system issues and PLC configuration issues. The only link I cannot verify is that from the converter box to the PLC, I am not sure if the PLC can push hostlink data that has not been requested. I have no idea why I can write to the PLC but not read. If anyone can provide any insights, I would greatly appreciate it, It has been two days and I am stuck. I am looking at maybe getting a logic analyzer to try and see what the PLC is sending back, but that will be months away. I am happy to try any suggestions

Hi, After a long time, searching for missing communication I think to have found the cause. In this CMP2A plc there is a receiving device connected to the RS-232 port. . During operation it can happen that in the same cycle there will be 2 functions to send different data.. I never receive those 2 data, only 1 is received. I can set a delay for sending this but this seems to be 'overkill', Is there a simpler way to do this..? The 2 pics are part of the program. After putting the P_off before the other transmits, I always receive the TXD(48) DM1621... Please advise,

Hi, I have a problem with serial communication (no protocol) using rs485 module, the received data is error. I'm using CP1L CPU, CP1W-CIF11 module as transmitter, and USB to RS485 converter as receiver. When I check the received data on PC, it's incorrect (bit error?). I just send 2 bytes data, 0x61 ('a') and 0x62 ('b'). My configuration: DIP switch CPU 4 = off, DIP switch CIF11 1 to 6 = on,on,on,off,off,off, 2 wire RS485. (I also attached the program and settings) https://postimg.cc/gallery/pr293Jc Could you help me to solve this problem? Thanks Program and Settings: Result:

I have a cell phone modem connected to my Omron CP1L on serial 2 Here is the issue I need to pull the phone number out of the msg received (receiving text messages) I receive a text msg and a lot of other crap like time and date ect. RDX says store in D100 the problem is that after I receive the SMS I see the phone number and copy the number to D200 to D2xx The next text comes in and it is added to the length of the previous text and the new phone number is not in the same D area as the first. It seems the only time the serial port works is if you declare 20 characters and you get 20 characters Works every time. But sometimes I may get 12 characters and other times I can get more than 100. I have used the restart and clear port command with no luck. If I set RDX to a large number and receive complete will not come on and the next receive will be added to the first. I need a clear buffer for each receive. How do I get around this? If you set the RDX to 10 but 12 characters were received the 2 extra characters will be in the buffer and added to the next receive. I can’t use end receive if x because there is nothing that is always available in the msg. And even if I do any characters received after end code is left in the buffer and screws up the next receive. I have never seen anything like this. Any ideas? Thanks Rob

Sorry its long !! I am recieving text from a GSM modem for text msg Send and receive (SMS) works ok but would be better if I could make use of the start code and end code. This way I could cut down on all the crap that is received when a text arrives. I get this CMTI: "SM",0 I have it stored into D80 and I have that trigger a TXD that sends AT+CMGRD=0 and that tells the GSM to send the msg (The 0 is the current msg in memory) ------ The problem is that there is Carriage Return and Line Feeds in the received msg ---- AS below ((AT+CMGRD=0 +CMGRD: "REC UNREAD","+19028991212","","22/10/20,16:57:54-16" Hello this is the msg OK)) When the PLC sees the carriage return it stops receiving data. And I have no start code or end code setup. (I am using characters received) The way around this is to set a high character count in the RXD (More than the actual msg (More than the msg length) The main issue with that is I get garbage in as the msg gets bigger. Its unreliable. I clear the port after each receive and that helps but still get the odd garbage. (Never get garbage when connected to a terminal prg). Any Ideas???? ps Even the Start Code is unreliable as it will start receiving a few characters late. Rob

I have a CP1L-EM and the serial ports - both of them have an issue with the port ready flag will not turn on. Power cycle still no port ready flag In settings both ports are set up as 15200 8N1 CR/LF Verified and power cycled and still no port ready flag. Is there someplace in the PLC where the ports can be disabled? Rob

Looking for a good USB to Serial (RS232) Converter
KnuckleDragger posted a topic in General Topics - The Lounge
Until recently, I haven't had to connect to a piece of hardware using a serial connection in quite sometime. Well, that all changed yesterday when I needed to connect to a Watlow F4T Controller. I dug around in the bottle drawer of my desk and pulled at not one, but two USB-Serial Converters that I saved for just such an occasion! My old ones worked on everything from Allen Bradley SLCs, to Schneider Drives. Unfortunately, neither appear to work in a Windows 10 environment. Searching the internet, I was not able to find any drivers for these old converters, but did find some posts in another forum stating that Microsoft changed how it manages its USB ports from Win 7 to Win 10. Thanks Microsoft! Sorry, I will cut this rant short and just ask my question. Can anyone recommend a USB-Serial Converter that works in a Windows 10/11 environment? Respectfully, Shane -
How to use a serial to Ethernet converter to send data to RSlogix
Walks posted a topic in Allen Bradley / Rockwell Automation
I'm trying to understand the basics of using a serial to ethernet converter such as this Comtrol DM-EIP-2101, with Studio5000 code. Basically I have a weighing machine that only outputs data via RS-232 and I need to send that data to a PC that will process it through a Studio5000 program and have the data displayed on an HMI using FTview SE. Is it as simple as just connecting the serial and ethernet to the converter and it does all the work? Obviously checking ip addresses and firmware will need to be verified. The main thing I am unsure of is the process of passing the individual data packets from the machine to the Logix code on the PC, things like what the weight of the item was, was it over weight or under, etc.... Would there be an AOI or tags built into the software for a machine like this Checkweigher? I've worked with much smaller items like Cognex Dataman cameras and I know you can just use their AOI that allows you to simply call a tag if you want to display information like if a scanned barcode was correct or whatever. If anyone has done something similar I'd appreciate any guidance. It can be difficult getting the information from the manufactures so I'm looking for answers anywhere I can. EDIT: I guess I should also clarify that only using one or the other (serial or E/IP) is not an option. It will be a serial connection from the Weighing machine to the converter and then Ethernet to the PC. -
Dear forum, I am facing a trouble at the moment and hoping somebody can assist. I have one HMI software, GT Designer 3, HMI: GS2107 and/or GT2107, the software works so far so fine. The software is used on several products, I dont want to maintain two or even more software versions. Two serial devices are connect: 1x MODBUS RS-485 1x MODBUS RS-232. The data transfer is done via DDT, no direct calls. The DDT transfer the MODBUS address to the internal GD-Registers. The GD-Registers are used within the HMI. My trouble is that in some cases, there is no RS-232 device connected. This creates time outs, slows down the HMI and its just not nice looking (I have a warning implemented "WARNING NO CONNECTION TO SERIAL DEVICE RS-232". Is there a way, that I can select (retained) that the RS-232 is connected / or not? Once the software is configured "NO RS-232 CONNECTED" I can handle the rest of the software. Anybody an idea how to do this? Many thanks.

I am at a client site that has a line with multiple Omron G9SP-N20S safety controllers installed and I need to make a modification to the system. I tried to install the Omron Configurator and it asks for a serial number, and will not install without one. Omron said that it is on the CD that ships with the unit, but the equipment manufacturer did not supply any of the CDs. The only Omron solution is to order a replacement CD, that will take 5 days, which is 5 days too long as there is a hard stop in 2 days. I have tried entering numbers found on the controller, with no success. Does anyone have a better way, special contacts at Omron, to et it faster?

Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter. The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs. The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...

I am trying to get a G9SP taking over serial to a NX1P2 using a NX1W-CIF01. I have the details in Manual P545-E1 and it uses a example file which i am unable to locate OMRON_G9SP_SERI232_LD_EV100.SMC I have got the coms working with a CP1L using the example in Manual Z922-E1. I was wondering if anyone has the example file or a working example they can share for Sysmac Studio. The serial comms will take a little bit to get going but it is the code for the checksum for the sending data that i would rather not have to translate from CX Programer fort he CP1L to Sysmac Studio......

Hello, I've been using Mitsubishi and Omron systems separately (in their own environment), and I am fairly new when it comes to connecting these two brands together(plc and hmi). I've been scouring the net for wiring diagrams for the cable connections and also the parameters to be set for a successful communication between those two components. can anyone point me at the right direction as everything I've tried so far has been a failed attempt of making these two communicate. here are the parts and my current settings if this helps: FX3U-64M FX3U-232-BD NB5Q-TW00B or better yet, is there a proper cable that I need to buy for this to work?

Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.

Hello to everyone. I hope you are doing well. I have a KINCO PLC HP043-20DT. I'm communicating through free-protocol instructions XMT and RCV. The manual states that memory registers SMB86, SMB186 and SMB286 contain information about the state of the reception instruction. I would like to ask if any of you know of the existence of an analog register but with respect to the transmission instruction, instead of the reception. The manual does not indicate it and I could not find any information online. I've sended an email to the manufacturer but, until now, I have not receive any answer. Otherwise, how could I search for this information? I tried through the manual providede by the manufacturer, but maybe there is other way. I would appreciate any information. Thank you so much. Kind regards.

Hello, denizens of Mr.PLC. I'm trying to talk to an old TSX17-20, and have acquired the DOS files for PL7 22. However, when installing via floppy drive, I'm getting a fatal error saying that the User Interface is missing. FATAL ERROR: 251 Your Telemecanique system in incomplete. Ensure that User Interface is correctly installed. I'm aware that PL722 (and PL7-1/2/3, etc.) require Telemecanique's DOS User Interface to run, but I can't for the life of me find installation files, and, as it is no longer supported by Schneider, no luck getting it from their site. Apparently, it used to be hosted there. Would any of you wonderful folk have the links or files to this user interface? Apparently, PL7 22 5.0/5.1 have never required/no longer require a license. It was a drag to find these files, so I'm posting the PL722 files (in two zips, representing the two floppies) so that there's an easy to find reference for them. PL722D1.ZIP PL722D2.ZIP

Hi there, I am fairly new to programming serial communications, especially with Mitsubishi PLCs. Can someone walk me through in ladder logic how to bring in ASCII to the PLC, store the data in the data registers. Then send the data out to another PC once an 'X' input is satisfied? ASCII code would go like the following: C2,0,1,123,2,ABC,3,456,CR

Micro 850- ASCII query/command and response
Arceus posted a topic in Allen Bradley / Rockwell Automation
Hello all, I am working on a project where I am communicating with a Mensor CPT6100 pressure transducer using a Micro-850 PLC. For this, I have used an AWA instruction to write some ASCII characters to the sensor. The sensor then responds to the write instruction by sending ASCII characters to the RX buffer and I used ACB and ARD instructions to read the ASCII characters. Now, I have set the ACB trigger type to 0 (msg triggered only once) and it successfully reads from the sensor. However, when I set the ACB trigger type to 1 (msg triggered multiple times), I do not get any reading in the ARD block. As a matter of fact, the ACB Q bit switches off every time the program is executed when the trigger type is set to 1. I am trying to get continuous readings from the sensor, but when the trigger type is set to 0, the program latches on to the first and only reading and it won't change. My question is, how can I change my program so that it can continuously and autonomously read from the sensor without me having to manually trigger the AWA and ACB instructions every time. I am attaching the program to this thread for your reference. ASCII_Test_Copy.ccwarc -
Hey Everyone, My company decided to purchase a piece of equipment from China, and I have the pleasure of updating its terrible existing controls. We were given the PLC program by the manufacturer, so I was able to make my changes pretty easily - or at least that would be the case if I could actually connect to the dang thing. The source program is indeed openable and editable via GX developer (the original configuration shows it as an FX3). I figured connecting should be straightforward, but I was wrong. I initially used a serial/usb converter that I've used on some older Allen Bradley equipment (which worked fine for that). However, after no luck using it on the "Mitsubishi", I purchased a different cable that I found recommended on this forum (Tripp Lite USA-19HS - https://www.alliedelec.com/product/tripp-lite/usa-19hs/70101537/?gclid=Cj0KCQiAj9iBBhCJARIsAE9qRtB_n8TVAnJdFyYokoEu42W6H6LaT4kVsgJQI1qvPUsUF3rFviKpbt0aApLHEALw_wcB&gclsrc=aw.ds). Still, no luck. I've tried 7E1 and every baud rate possible, as well as some other bit/parity configurations (and yes, I've verified that I'm using the right com port, as well as tried moving the converter to different ports and trying those). Nothing seems to go through. I have almost no experience with Mitsubishi beyond a couple of FX5s (which have worked fine, but I connect to those via ethernet). Any help would be greatly appreciated; if I can't make these changes, I'm going to end up rebuilding the whole cabinet with a PLC I can rely on. Thanks in advance.
