4. General Operation
CS7A - Serial Control, is on a separate IOC because it can be processor intensive and affect critical control loops.
CS7C – Serial Control.
CS7B – Analogue and Status (On-Off) Control. This IOC should perform equipment protection functions and sequence control.

5. Recent Work Reducing spurious readouts and “white outs”
Allowing more time for the equipment to respond.
Reducing control system processor load.
Filtering out any obviously incorrect readings.
Incorrect settings
Lakeshore insecure protocol corrected by not asking for the set point which can be corrupted to a set point command.

6. Conclusions
All the recent work done point to the serial problems being with the manufacturers of the equipment being controlled and not with the control system.
The work that has been done is all to reduce the effects of the limitations of the equipment.
We can continue to tweak the controls interface to make the reduce the load on the equipment.
