Experimental Physics and Industrial Control System
Sheng,
I visited SNS a few weeks ago and Ernest showed me the Beckhoff
hardware which he said you wrote a modbus driver/device support for.
Was that working well? I am thinking of trying out the Beckhoff stuff.
I will be supporting some modbus tcp/ip devices in the near future and
have the CLS and some upgraded (APS?) source but haven't looked at it
yet. What limitation did that have for you, so that you needed to
write a new version?
Regards,

So far as I know there are at least two of ModbusTCP support.
One is originally from Canada and has been updated couple of time for
different purpose.
Another one I developed in SNS is kinda new.
Since I wrote the new one and read thru all the source code of the
previous one, I hope I can give you more information about which one
might be better for you. I will go back to US tomorrow. Please tell me
what is your application.
Sheng

Subject: modbus over tcp/ip
Hi,
There are a number of sites supporting modbus over tcp/ip. Can the
experts recommend a package for us to use at Fermilab?
Thanks, Geoff
