  4. Hello   i have a versamax icu200udr064 and i want to connect it with simatic basic panel ktp 1200 dp  both support modbus rut but the problem is that i cant find GE communication driver on the tia portal by whom i program the HMI.  One more thing is that i found a communication driver for modbus rtu but the tags addresses are in the standard form for modbus, so is there any solution for this?  thanks a lot .  
  5. Hi Everyone! Where are my experts? I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever! I am using the Schneider M258 with SoMachine 4.1 The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now. I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop.   1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser. 2) As a trial can I send him MODBUS commands regarding my AND circuit? 3) How do I create such a command? 4) Is it possible for him to send me Modbus commands to change variables inside my program? 5) Are there web browser "plug-ins" for this idea? Thanks for reading and hopefully all of you can help me answer some of these questions.

  10. Hi all,   currently as part of a project I am trying to communicate between a Schneider M340 plc and an Allen Bradley micrologix processor. I am programming the M340 and the micrologix has been installed by another supplier. they have mapped the Modbus registers on their side and given me a spreadsheet with these.  I am able to read values with no issue but I cannot write values back.   i've included a screenshot or the read_var and write_var instructions I am using. I would really appreciate any help if anyone has any insight on this   Mark

  11. NJ501 MODBUS TCP/IP COMMUNICATION ISSUE

    dipen_95 posted a topic in Omron

    I am trying to get the communication going between EZ3 EZAutomation Panel HMI and Omron NJ501-1300 PLC. I am currently using Modbus TCP/IP as a protocol. Has anybody figured out a way to do that? Or is there a better way to do this communication between HMI and PLC ? Right now I am using MTCP_Client_Connect function block to connect with HMI but it dont seem to be working. The IP address is correct along with Port no. I am still fuzzy about the Station address of NJ and the function code of the NJ for Modbus purposes. If anybody could help me out I would really appreciate it.

  12. Omron MODBus

    downerczx posted a topic in CX-Programmer

    I'm attempting to connect a CJ1W-SCU32 modbus card with 2 ports to several modbus sensors. I am only reading from the senors, not sending any commands. I have been told two different ways to do this: 1. CMND block using Modbus RTU code 2804. 2. Using the Protocol Macro ModbusPM_Master with the PMCR function block. I've additionally found an easy modbus configuration tool that unfortunately seems to take up too many registers that I will be using. Does anyone have any examples of code for setting up MODBUS TCP with either of those 2 methods? I am having a hard time finding any. Thanks.
  13. Hi Everyone, I am trying to connect a Toshiba TRSPUX10A plc to a hitech PWS6600 HMI (Beijer electronics). I am using RS485 connection, and trying to get the communication going between the plc and hmi using Modbus RTU protocol. The PLC is slave and and HMI is Master, and I have a Modbus slave tag table for the plc. HMI Software: ADP3 PLC Software: TRPGMS01 Our supplier of the product cannot assist me as he passed away, and the manufacturers of the systems refer me to each other but with no luck. I have asked numerous system integrators however they only work with the systems they supply. I want to read a Modbus slave tag: Holding register 4500001 in the plc and have it displayed on the hmi. Please advise if anyone could assist. Kind Regards Quintin          
  14. Hi everybody. I have 1 QJ71C24n-R4 with 2 channels CH1 & CH2 and I want to use Modbus RTU for both of channels to read data from electric meter. Now I can do it well with CH2 but cannot with CH1. The reason is echo back setting, my GX work 2 only able to prohibit echo back on CH2, not able on CH1. Does anyone know about this problem? Please give me some advise. Thank you so much.
  15. Hello everyone, I have difficulty to setting up the GSM configuration or the serial RTU configuration so that I allow you with another RTU.

This is the first time I'm working on this kind of project, want to help me, I'm stuck and I need a solution, thank you for your time.  

  16. datalink - Etehrnet send recieve CJ2M Cpu

    Chickenkiller91 posted a topic in CX-Programmer

    Hi guys. I have 1 cj2m cpu33 reciving 3bits of info from 3 other plcs (all similar type cj2m cpu 34-33) The problem is that 2 bits are ariving the third one is not. See the pictures i uploaded:   I do not know these instructions, in the other cases it was working. However i noticed that the output plc had a different adress with D950. I changed the adress to D804 as you can see on the pictures but still not reciving the data.  I guess i will have to configure somwhere else also. All i found (https://www.myomron.com/index.php?action=kb&article=1416) on internet that i have to open this datalink tool from the integrator. When i actually do that of course i just get an error: FATAL Error. Cannot read the file.   How can i make this work? Is the other way to constantly send this one bit with ethernet? Any sollutions, advices are welcome!

  17. S7-1500 FW v 2 / Profinet issues non-Siemens devices

    PLC_guy_in_Yokohama posted a topic in Siemens

    Hello: Has any body encountered Profinet IO cyclic communication establishment problems between the latest S7-1500 PLC with firmware 2.0 or later and non-Siemens Profinet devices which had previously passed conformance testing campaigns? Thanks for your comments.    
  18. Has anybody tried communicating Allen Bradley 5069 Compact logix PLC with Red Lion HMI ?  I am unable to communicate them in spite of adding AB tags via L5K file which gives me no error. I am able to see all the tags in Crimsion 3.0 software in development mode.  However, PLC & HMI are not communicating with each other. I am able to ping to both, using the same program in PLC of which I generated L5K file.  I think it may have something to do with the driver as 5069 is a new line of PLC Rockwell come out with only in 2016.   

  19. HELP WITH WPLSOFT DELTA PLC

    Omerd posted a topic in Other PLCs

    Hello , I'm using DVP12SE11R Delta PLC . I would like to read data from an external device using RS485 communication. In the WPLSOFT i have informed that i gotta use MODRD command in order to read the data . but i am not sure how to use it properly.  the data is formed as one bit ('1' or '0') i wanna read 10 registers using MODRD although those registers are not ordered one after another and i know MODRD can read 6 registers one after another. Then i would like to use that bit as a Normally Open contact in the WPLSOFT and turn on a coil. i would like to get some help with it. thanks.

  23. Socket communication with Micro820

    Anthony Blanchette-Potvin posted a topic in Allen Bradley / Rockwell Automation

    Hi everyone ! I have a little project wich involves communication between two Micro820 controllers via TCP/IP. To do that, I started to work with TCP/IP socket. Within CCW (Connected Components Workbench), I tried to create a new socket instance using the instruction SOCKET_CREATE and set the socket address to 127.0.0.1:21. Basically, my computer through the FTP port. The problem was that it couldn't create a new socket instance (error variable is set to TRUE and status is set to 4, wich I don't know the meaning) because I didn't have a server-side application that listens to TCP/IP socket requests. That said, I found an open source application called SocketTest that listens for TCP/IP socket requests on a specified IP address and port. So, I started a listener on the following address : 127.0.0.1:21, but the error variable is still set to TRUE and status is still set to 4. So, my questions are : Is my IP address OK ? Is my port number OK ? What means the status code 4 ? Is SocketTest doing what I think it does ? Do I need to do something else before using the SOCKET_CREATE instruction ? Thank you in advance for your help !
  24. hello everyone, I'm trying to connect PC with Micro830 with RS232 cable for transfer serial data. However, the PLC can not receive the character from PC. I used ARD function block to read the characters from PC.  there is no error and the output of ARD function block is 0 when I debug ladder programme. the serial communication state LED illuminated once I send a character from PC to PLC. the channel of input is 2 which is the embedded serial port. I use an adapter from USB to RS232. Email: jeremietang531@gmail.com      

  25. Mitsubishi iQ-R Series

    CementMatt posted a topic in Mitsubishi

    Hi Has anyone got any real life experience with the new Mitsubishi iQ-R series?  I have been assigned a major capital project to replace our old ageing DCS system.  Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest.  However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series.  A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package.  Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales.  Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful.  I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt
