Hi Linda,
some time ago I also had an Eurotherm on the desk and after some testing
with the provided "driver", I decided to write my own code. I can send it to
you if you want. It does not cover all the device functions but it does the
most important (read/write setpoint and process variable) and is probably a
good starting point.
Please note: The driver uses the EI-BISYNCH protocol! This must be selected
in the Eurotherm!
If you are interested, send a mail to tl@kayser-threde.de
