Re: EPICS to WAGO PLC using Ethernet MODBUS

[Rolf Keitel <rolf@triumf.ca>]

At TRIUMF we have been running our EPICS device/driver support  for 
Modbus/TCP for the past 6 years. We are interfacing to MODICON Quantum 
series and Momentum series PLCs.  Driver was written for VxWorks and 
tested on MV162s, an 486 based PC104 board and the GMS Mariner 
(VME/Pentium).

More details at http://isacwserv.triumf.ca/epics/modtcp/TRIUMFmodtcp.html
