  1. OMRON CJ1W-ETN21 Node Number

    Hello. I'm having CJ1M unit with ETN21 card on remote site. I can't drive to the site and look at the rotary switches to determine what is the units NODE NUMBER. I can connect to the PLC remotely using CX-Programmer. Is it possible to read the setting of NODE NUMBER remotely? Is this NODE NUMBER settings saved somewhere in CIO or DM area? Thanks. BR, Andrej.
  2. Hi, I have a CP1L and CP1E Omron PLC, and I try to make communication between my PLCs and my system (raspberry pi with Linux OS) using Node-red and specifically using the OMRON-FINS node ( https://flows.nodered.org/node/node-red-contrib-omron-fins) and more detail ( https://github.com/ptrks/node-omron-fins ). So I’m looking for a module to create an Ethernet port for my PLCs. ( both PLCs have RS232 port) . Can you please guide me to find a compatible RS232 to Ethernet module for my PLCs?  Thank you
  3. Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems.   Best Regards, BR  
  4. Good Morning, I connect using a TCPSocket a remote node with my NJ501-1300. In order to test communication with the remote node I use a telnet communication and send from it messages to the remote node: it work correctly opening the connection and then sending all messages I want; the connection will close only at the end of the communication session. WHAT HAPPEN ON NJ? On NJ Open connection whit remote node; Connection is open; Send first message to remote node; Receive correct answer from remote node; Send another ore the same message to remote node; Receive an unknown command answer from remote node. WHY??? To solve previous problem I need to: Close the open connection; Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; Close connection Wait the time to reopen it; Reopen connection; send the message; receive the correct answer from the remote node; close connection and so on... Could someone help me to solve this problem opening the connection only once and then close it at the end of the end of communication session?!   THANK YOU
  5. Net.Node.Unit on EtherNet/IP

    Hi, I am connecting several computers and NS12 HMIs with a CJ2 PLC using EtherNet/IP protocol. And I would like to know the FINS Address (Net.Node.Unit) of the HMI and the computers. I suppose I need to fix their addresses using an IP Address Table. Right?? Anyway, I only know to do that with UDP or TCP, but I don't know how to do that under Ethernet/IP. Thank you.
  6. I recently had an issue where a system shipped to a customer's site with a mismatch between the IP address loaded into the CJ1W-ETN21 card and the node dials on the card itself.  We had been testing the settings of the card by pinging the address and had assumed if the node dials were wrong we would not be able to ping the card.  As we just found out that is not the case! Both our quality department and our customer's end user were able to ping the Ethernet card, but the end user could not establish FINS communications because the node dials were not correctly set. Is there a way to test that the dials are correctly set?    Thank you!!!
