  2. I am trying to POST API to a meter in Maximo using a socket in a 5069-L320 controller. I am able to successfully create and open the socket. The write and read instructions get the DN bit but I do not see the meter updating in Maximo. I was able POST successfully using Postman, so I know I am sending the correct information. Do I need to be formatting the POST differently? I'm not getting errors so don't have a direction to go from here. (I will fix the obvious username and password vulnerability, one step at a time) Thanks
  3. 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 
  4. 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.
  5. 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.

  7. 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?

  9. HOSTLink read multiple DMs

      Hello,    I am using Hostlink protocol to read data from PLC units. for example @00RD22220001..., will return DM2222's value. But I want to know, if I could read multiple DM values at the same time. for example: DM2222, DM3000, DM4000, reading these DMs with one communication. Please note that these are not continuous DM areas. I know a sequence of DMs can be read by specifying starting address and count.   Many thanks in advance.   Ting              
  10. 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...

  11. 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......

  14. Good Morning,   My name is Joseph Rhodes, I work as an electronic technician for the City of Tuscaloosa at the wastewater treatment plant. I work to keep the plant up and running as well as 64 lift stations spread out around Tuscaloosa, Alabama. A majority of our lift stations utilize Verizon Cell Modems, RV50s to be exact. It's rather easy connecting remotely to these lift stations as I can configure a driver as an ethernet / ip driver then associate an IP of that lift station (ex. 10.181.3.104 is lift station 104, 10.181.3.105 is lift station 105, etc). However, for the lift stations that do not utilize cell modems. We use GE MDS 9710 and 9810 radios. It is these lift stations that I have yet to figure out a way to connect remotely to the LS RTU PLC. All of our lift stations use Allen Bradley MicroLogix 1200s or 1400s. These lift stations that use the MDS radios communicate information to water tanks then that information is sent back through other channels. I was wondering is there a way to associate these lift stations on RSLinx that use GE MDS radios ?   
  15. Hi all, I am trying to communicate KEPServerEX with FX3GE vis UDP protocol. I have tried but unable to get data on Kepserver. While configuring communication properties in PLC we have configured PLC IP, PLC Port, Destination IP, but unable to find correct Destination Port. Although we tried various port nos like 49320, 57412, 57512, 56233, 1025, 32402, 57212, 57012, 57612, 57812 but there was bad quality data using UDP For same PLC using TCP/IP we were able to read all tags properly. This change in communication protocol is required as there are some PLCs whose communication port drops after few days of connection establishment (no error logged; can be re established with just restart). Someone from Mitsubishi said to try communication via UDP as it continuously fetch data regardless of kind of response received. If anybody has tried or have any solution, please do share.   Thanks
  16. 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?
  17. Hi, I managed to communicate a Kinco HMI with a Xinje PLC (XC3-48R) using RS-232. Also, I've established connections between the both equipment and my personal PC, for programming purposes. Currently the uploading and downloading, PLC bits reading and writing happens normally. But, when I disconnect any of the equipment from the PC, (HMI or PLC), the communication is lost between the PLC and HMI.  How can I solve this and, remove my PC from the network by making the HMI master and PLC slave ?    The software I use for programming is, (XCP Pro, Kinco HMIware)  
  18. FX3GE Communication issue

    Hi all, There's an issue I am facing for multiple FX3GE PLCs in a plant. Communication breaks between a PLC and OPC server. PLCs after few days (4-10) does not respond over ethernet. No ping response is received over network as well as when checked one to one direct connection. If I restart the PLC the connection is resumed and again after some days it goes down. Error LED on ethernet port does not glow red (no indication for error). If anybody has faced similar issue and has resolved, please share.
  19. 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.
  20. 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.

  25. Monitouch HMI slow screen

    Hi there! I'm having some issues with a FUJI MONITOUCH V9100iSD HMI that communicates with a CJ2 PLC via Ethernet. This HMI is a migration from a previous V810iSD model. The thing is that the previous model worked correctly, but when using the new one, the HMI seems to be pretty slow when switching screens, for example. All parameters are the same, and after reading Fuji's FAQ, I've run out of ideas. Have you faced the same problem? Thanks in advance!
