Re: EPICS to WAGO PLC using Ethernet MODBUS

[Eric Williams <ECWilliams@lbl.gov>]

John,
Can you please email me with a place where I can get this?

I think the EPICS community should settle on one of these to concentrate 
their efforts on.  I've been doing a survey of PLCs with Ethernet field 
bus capability, and MODBUS over TCP/IP is the most common protocol in 
the market.
