Experimental Physics and
Industrial Control System

Here is a module and and ioc build that implements a small set of Eurotherm gets and sets.  The approach to using the modbus is somewhat unusual by EPICS conventions but you may find parts of it useful.  It has run reliably for a year.  Done with EPICS R3.14.9.

I have been searching for temperature controllers which allow for 10 (or more) PID control loops, and have come across the Eurotherm 2704VC controller (this particular controller has extra inputs and outputs for vacuum equipment).

I have found support written originally for the Eurotherm 800 series controllers on the Modules page, and have been told it works for the 2000 series even though it should not.
