I would like to read and write variables in my CJ2M omron PLC (RJ45 connection) with Delphi 7 , could you help me with an example or point me to a solution please ? Thank you to all.

Hello, You need to write some code that uses one of the Omron protocols. Omron publishes all the protocols in manuals. W342-E1-11 is a good manual. There are many manuals PeakHMI supports Omron. You can use the demo version if you want to snoop the packets or the full version if it fits your needs.

I assume when you say RJ45 connection you mean the Ethernet port. Look into OPC servers as a way to read data from the controller. They already have all the protocols built in. Or as was suggested, read the manual on the protocol and write the code to create the proper packet formats.

Search for the term"FINS" on this forum. You should get quite a lot of examples. Also look in the Omron download section.
