Industrial Control System

Hi Bill,
 
I think you should try the new Modbus module I wrote.  It may need a small enhancement for Wago support, because I think the address to read from is offset from the address to write to.  I gathered that from the NSLS source code, but I don't have the documentation to verify it.  I had anticipated that, and there is a device string in the configuration command that can be used to identify what kind of PLC it is.

Subject: Current State of Wago support ? 



Is the device support for wago controllers from the NSLS detector dev
group still  most current ?

Does any one have a different small controller that they like better ?
I need only basic BO/I and AI support at the moment.

Thanks,
--Bill
