Logging: Eurotherm

[John-Holt-Tessella]

As a support person I don't want the eurotherm to log a message everytime it finds it can't talk with it because it makes the log very big and potentially fills up the disk.

Acceptance Criteria

• When eurotherm can not contact the device a message is logged (possibly one for each opv)
• After this no other messages are logged

Notes

• I thought we already did this has that got broken? in ticket CCD100 IOC: reduce logging when disconnected #2916

Maybe because multiple things are accessing the port it confuses the current check?

Given the difference in behaviour for a 'bank' of Eurotherms as opposed to most devices which are single items this needs a bit more discussion and information to be able to point it
