  1. Hello, I'm trying to connect a CJ1M-ETN21 as slave Modbus TCP with a Modbus/Dali Gateway. I download from Omron website some FB with ones should be possible.   https://www.myomron.com/index.php?action=kb&article=1245 The FB only can be used with the direction unit 0, but we can change some directions inside the FB and can be adjusted to other units. In the download I found this FB: MTCP_ETN_Connect, MTCP_ETN_Fn01, MTCP_ETN_Fn02, MTCP_ETN_Fn03 .... Supposed with connect we can establish the connection with the master, but the FB never make nothing. Should I make some special configurations to use this FB? I appreciate any help. Thanks

  5. I'm trying to communicate with INVT PLC and DGM8002(grain moisture analyzer) via mobus RTU.   Can anyone explain about these Modbus address ? Please kindly see in picture . example working mode address K0 (0-stop ,1-manual,  2-Auto) Actual Moisture Address K6 What is meaning of K0,K1,K3,K6.  https://drive.google.com/file/d/1-mGzpEvw4UlewWhR9k3wOd1mO-uhsklL/view?usp=drivesdk Is that K0= 0000 K2 = 2000. K3=3000 ? Any suggestion please. I'm really appreciated your comments.❤️

  7. Create TCP/UDP Socket

    I'm trying to send an int over TCP using a MSG Socket,  Compactlogix ==> Arduino Ethernet Shield I have set up TCP communication between two Arduino Uno's using Ethernet shield. I've set up the one as a server, the other as a client. server IP: 192.168.1.21 port 23. If the client is connected it reads incoming data as a byte or an array of bytes. The data between the two has been verified to work. I'm now trying to transition the communications between a compact logix-L32E. I'm looking to send a byte (or int being as there's no byte data type) from the Compactlogix to the Arduino using TCP. To my understanding I need to use a socket create, open, read/write, close. The manual to do this is vague as a step by step procedure. Does anyone have an example code for socket programming? I can open rs500, rs5000, and studio 5000 programs. If I can open a file to use as a reference I can translate it on my own. Any help/advice would be greatly appreciated. 
  8. Q03UDVCPU Modbus Setup

    Hi Guys, I need help to set up modbus tcp/ip parameter for Q03UDVCPU, i want to use the predifined protocol and built in ethernet port. do you guys have some usefull references how to setup modbus tcp/ip, or is there any example program from mitsubishi? Thanks
  9. Dear Engineerds,   My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584   Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0)   I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx
  10. CP1L-EM Socket Communication

    Good afternoon. I am trying to carry out the communication of a CP1L-EM by TCP socket with a scale module, however I still haven't been successful. I have the Open_socket, Send_Socket and Close_Socket blocks. I tried to make a Receive_socket block but I don't know if something is wrong. Does anyone have the Receive_Socket block tested with CP1L-EM available to supply me? I am very grateful!
  11. From DM:   Hi; my name is Metin , I live in turkey. unfortunately I have a problem that I could not reach a conclusion here. I hope you can help. I need to communicate with CJ1W-ETN21 with a device via modbus tcp and read information. I downloaded ready-made protocols on omron site, connection is established but I cannot read. I tried the attached protocols. the device I am trying to communicate with :  https://www.gmweighing.com/products/weighing-indicator-m02  I will get the weight information from the weighing device. Thank you in advance for your help. MTCP_ETN_Client.zip
  12. Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use   My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI   I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling   Tom

  15. hello expert i want ask some help So i tried to communicate my Omron PLC (cj2m cpu31) with SCADA from Schneider (power logic) on my omron side the comunnication on PLC already take to communication to NB so i add communication module CJ1W-SCU41-v1 I want asking how to open the communication if i want the scada become a master and my plc become slave i got this from omron website is that program compete for my case? i need configuration for scu41 module also to communicate or if you have suggestion i really open i just need to open port RS232c from scu41 so scada can read the data from my plc  tahnkyou for your help MRTU_CPU_Slave.zip
  16. Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8  = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR    this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000   any help will be greatly appreciated.

  19. Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help!

  24. i am trying to communication my weintek HMI with Siemens Energy Meter PAC3200. I am using MODBUS TCP/IP Protocol but i am unable to read the data register of my energy meter. Somehow i got to read the 32bit data register but still unable to read the 64bit data register of my total KWHr Energy consumption. I have also attached the manual of my energy meter. Please guide how to read all the data registers of that energy meter. Please see the page 40 onwards for reference. The manual the about 7MB so i cannot attach the file. https://support.industry.siemens.com/cs/attachments/26504150/A5E01168664B-04_EN-US_122016_201612221316360495.pdf
