  1. Serial question

    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  
  2. Hello everyone, I want to use my own computer as plc. I have a molex brand SST-PB3-PCU SST card. I will connect my I/O modules to the profibus adapter, then I will connect the adapter to the SST card. Can Codesys see this SST card and if so how do I make the connection. I can connect this type of connection in the InControl (an old software) program that I used before.  Please Help Me!! The Board I use to connect the I/Os to the computer: SST-PB3-PCU  Profibus Adapter to which I connect I/Os: 1794-APB | Allen Bradley PROFIBUS Adapter Module My I/O Modules: Allen Bradley 1794-IB16 and 1794-OB16 My OS: Win10 64 bit Codesys Version: CODESYS V3.5 SP18 Patch 3
  3. Serial Port issue

    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  
  4. Serial Ports not working

    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  
  5. 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 
  6. 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.
  7. 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.
  8. I would like to get some feedback or alternate suggestions in terms of monitoring a database connection. The attachment here shows the current programming for the DB_Connect function block which requires the Execute input to constantly be ON.  From what I can tell, if the connection is dropped - let's just say the Ethernet cable is unplugged - this input will still be on, and according to the function block, still connected. The Get1minClk is in place to continuously try establish this connection once powered on, but I cannot find any way to periodically check this connection without dropping it and reestablishing it.  My understanding is the _DBC_Status.Run only checks that the PLC service is running properly, but is there a way to monitor a heartbeat of the connection TO the database?  The only way I've found thus far is to drop the connection and reconnect.  But this would be detrimental to the system as it would possibly be reconnecting to the database while trying to write to out to it and hold up the show.  As it stands in the second image, the Ethernet cable is unplugged, but the connection shows no errors. Thanks and happy Friday! -K  
  9. Hi, So I have a problem, that BootP DHCP server doesn't find my 1734 AENTR series B and so I can't assign IP address to it. Been trying many things. Any advice? I'm new to AB and I guess it may be a really easy thing but so far I didn't find a solution. 
  10. G9SP Configurator

    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?
  11. 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...

  12. 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......

  13. Sorry for my bad english speaking. I want to change the baud rate to 19200,38400,.... for send it via Programmer-Serial-Port. The software GX-Developer can do it!.  
  14. We have an SLC 5/05 on our automation network, one of several SLC 5/05 processors on site.  It functions perfectly well and no ethernet messaging issues or SCADA drop outs.  The difficulty I am experiencing with it is when I am required to fault diagnose it takes a very long time to get online to it with our laptop running RSLogix500.  It sometimes takes as long as 10 minutes.  It makes no difference whether I use the Ethernet devices or the EtherNet/IP Driver in RSLinx, it nearly always takes an age which is frustrating in a breakdown situation.  I don't ever experience these long wait times connecting to any other of the SLC 5/05 controllers or any other controllers for that matter.  Once I am connected to the problematic controller I don't experience any issues, it's just the initial time getting online.  I try to leave the laptop permanently connected to it to avoid the long wait time to connect.  When I open RSLogix500, select Comms, Who Active Go Online, Ethernet devices driver, I can see that the problematic 5/05 has Active as its Status whereas the other 5/05 processors have Remote Run as their status.  Please can anyone advise as to any possible program parameters, RSLinx settings or hardware faults I should be looking for?  I have considered it could be a network problem but I'm unsure about this given how the processor performs well in every other regard.

  15. 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?
  16. Serial communication with KINCO PLC

    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.
  17. Memory registers on KINCO PLC

    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.
  18. Hi all, currently I'm using NX1P2 PLC for my project. So I'm just using it to transfer data from PLC to my PC but I faced 1 major problem right now which is the connection. I have few experience working on PLC but this time I faced an issue which I don't know how to solve it. So the problem here is, my NX1P2 can't connect stable to my my PLC, initially I thought it was the cable problem, after I changed several cable it's still the same, so I thought it was my ethernet port problem but I can connect it to the internet and also Delta PLC, at last I thought it was PLC problem so I connected it to my colleague PC, they got a stable connection and able to program it. My ethernet keep on displaying "Enabled > Identifying > Unplugged", I check my Ethernet port, it using Intel(R) Ethernet Connection (6) I219-V. Tried to solve it for few days already, anyone faced this problem before? 
  19. CP1L Unknown IP

    Hello. I have CP1L EM30 with unknown IP. I have tried to use "Direct Ethernet Connection" with "Network Browser" but with no success. I have manually set the ethernet IP4 address to 192.168.20.20 / 255.255.255.0 I've got error: "The OMRON Ethernet Direct Connection Manager service is starting in Safe Mode because Windows APIPA is enabled. (0x82020003)Omron.Cxmw.Modules.SystemLibrary.SysLibException" The PLC does NOT have default ip 192.168.250.1. What Can I do? Please help. Thanks. BR, Andrej.  
  20. 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
  21. Is their any method like virtual port adding to advanced HMI and cx programmer to view input and output from advanced HMI to Cx-programmer.?    
  22. HI All,  I have an issue with my SCU32 communication.  Back ground Two SCU32s  (top and bottom side) connected via a 1100M datacable  using port1 ( 9600bps,  8-2-E, start code FF, end code FE, Tx save to d1000-d1200 , Rx save to d2000-d2200). PORT2 of bottom SCU32 is connected to a compass( 2 wire, 8-1-N, 19200 bps, serial gateway MODBUS ). Refer to photo Issue  Without compass, the receiving data at top is very stable and is didn't see any fluctuation. But if is compass is connected at bottom side port2, there is a fluctuation at the top side RX data(specifically d2000-d2005 ) .  I checked the data a bottom side TX (d1000-d1200) and it is stable. Only after sending the data and Receiving at Top side, then only the starting words fluctuate. I am not sure sure what is wrong, I am using logical ports for the DTXDU/DRXDU and compass.   Appreciate all your feedback and suggestions.  
  23. 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
  24. I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?
  25. 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.
