I am working on project where we integrate Omron Microscan Barcode reader to Schneider M218 PLC to read Barcode text. In Microscan we enabled TCP/IP and Port number. From scanner Data coming properly. But coming to PLC I am using Read_var function to Read Data from scanner. I am not getting Scanned text in PLC. Is there any alternative function to read TCP/IP with Port Number Data to read using PLC?

OMRON NJ Modbus TCP Slave ID
AGroves111 posted a topic in NJ Series / Sysmac StudioI'm looking at project with an OMRON NJ-101. I was planning on using Modbus TCP/IP from the PLC to talk to a MOXA gateway (MB3170) which would then talk to about 7 different slaves over RS-485. Looking at detail at the blocks that are supplied by OMRON (MTCP_NJ V1.3, available from https://www.myomron.com/index.php?action=kb&article=1245), I noticed that it doesn't send the slave ID, which will mean that it won't be able to talk to different slave ids through the one IP Address. I had a look through the actual code and it sends "FF" in place of the slave id. In particular I was looking at the "MTCP_Client_Fn03" block. Is there another way to get the NJ101 to talk the full MODBUS TCP/IP protocol? Is it possible to edit the blocks provided by OMRON? It seems to me that they are locked down. If I could edit it I could just add the functionality Thanks for your help in advance.
Modbus TCP/IP communication with controllogix redundancy
Rasu posted a topic in Allen Bradley / Rockwell AutomationI'm using Controllogix L61 redundancy system as a slave with DCS using ethernet tcp/ip socket programming. The communication between master and slave will fail after a switchover. Kindly give solution for this. Thanks and regards, Rasu
