PLC Omron CJ2M-CPU13

3 posts in this topic

I want to get values from PLC Omron CJ2M-CPU13 with distance about 100m. PLC has RS232 and USB port, RS232 used to connect to HMI and USB port cant connect with distance 100m. I think i will buy Ethernet module, its ok ?

How can i get values from Plc to VBA with Excel ?

You might get more answers if you had placed this in the Omron forum.  But yes, to go that kind of distance to a PC, the recommended solution will be Ethernet.  CJ1W-ETN21 or CJ1W-EIP21 for EtherNet/IP.

As for how to talk to it, that is documented in the manuals for those cards.  You may also find many examples here in the forums.  Many people will use an OPC server to collect the data and then access it in Excel, though there are other options.

Hi,

Yes agree with Crossbow. If you’re cash rich but time poor then purchase Omron’s CX-Server Lite. In 5 minutes you can write macros to read out data, or even link up controls without any coding. For me it’s worth saving my time
