Title: Do-more Ethernet
Post by: azeotrope on October 16, 2014, 05:01:33 PM

Hello all,

I have several Do-More H2 DM1E plc running on and ethernet loop with some c-more's and some VFD's Set up is pretty easy for items from AD.
I want to install a WEBRELAY into the mix. http://www.controlbyweb.com/webrelay/

I can see this on the network, can ping it etc but I can't for the life of me figure out how to get it to communicate with the PLC

Any ideas on how to go?

Thanks.
Tom J.

It looks like the Modbus/TCP Slave capability would be the key to use as a remote input/output point. Section 3.4 in its manual has the details. Use MRX and MWX commands in the Do-more to communicate.
