Description

The DCS Voltage display in the control room doesn't understand the difference between a zero value and a failure to read back a device.

This happened today when the network cable on the diblock 2 power supply was knocked loose. It appeared in the control room that the power to diblock 2 was off, but the event displayed showed that a subset of the DCMs where still taking data (one of them was still on, two had been turned off for maintenance)

This is bad in that if we aren't able to talk to one of our supplies we should know this, not simply display zeros.

History

#1 Updated by Leon Mualem over 8 years ago

We probably should add the display of diblock 3 and 4(?) at the same time as this is fixed.

#2 Updated by Chad Johnson over 8 years ago

Readout of DB 3 and MC has been added. The vendor supplied functions do not return error messages when communication with the PWS has been disconnected so this issue will take a little longer to resolve.
