Sorry I don't have that. All I got on the mail functionality is what we have on our support sitet and what is in the manual. www.myomron.com/index.php?action=kb&article=1256

Hi CJ1W-ETN21 is not an Ethernet/IP unit. What you can do is using the FB SEND and READ

OMRONTompa so how can i know that eNod4 already connected to plc ? And where i can use the memory address ?

Hi Were are you located? I think it is easier for you to contact your local Omron representative.

OMRONTompa www.myomron.com/index.php?article=1514&action=kb u mean this ? It said that FB only work for EIP, and will not work for ETN.. i’m from indonesia, and i’m already ask them about how to connect it but they only told me that it can’t and recommend me to use EIP module, but it’s so expensive... so I’m just trying to use what i have now..

Try to update CX-One to the latest version, if the problem persists contact your local OMRON support
