John/Eric,
We are willing to provide you with a copy of our version. At CLS we run
most of our IOC software under either RTEMS or Linux. In this
particular case the driver is written for RTEMS and has primarily been
used to talk to MODICON Momentum PLCs and a few other related
applications, such as power meters from PML. We are also willing to
look at merging in changes you may have made.
If there is wider interest I can have the driver and design note tossed
onto an ftp site.

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.

I have Ethernet-MODBUS support which is based on code obtained from the
Canadian Light Source. The CLS code is written to run on RTEMS and
supports Modicon PLCs.
I modified it to be OS independent, to work with 3.14.2 and to add
support for Siemens power meters.

Hi all,
I have to connect from EPICS to WAGO System PLC using MODBUS protocol
(via Ethernet).
Has anybody any software for such kind of communication?
Any suggestions and advise will be appreciated,
