Fast Cooling Furnace support

# Issue Description
As a user/instrument scientist I would like to be able to control the new fast cooling furnaces.

### How & Where?
These will have Omron PLCs and be controlled by OPCUA. In February I was told that the first prototype would be ready in July/August. There will eventually be 12 in total.
