8.7.3 Interlock Data
This page provides details of the operation of interlocks within the Pakscan IIS master station. Particular
outputs can be interlocked with status bits from other field units, or with items from the sequence data base
such as flags. Interlocks can only be set externally using the SCT programme and then down loaded to the
master station.
The first line shows whether any interlocks are active.
The remaining three lines show details of the most recent (if any) interlock failure to occur. If there has been
no failure they will be blank. It is necessary to refer to the interlock set up information from SCT to make full
use of the presented data.
Line 2 shows which interlock failed last.
Line 3 shows which output was affected.
Line 4 shows the first interlock condition which caused the failure.
On lines 3 and 4 inputs and outputs are shown as a 2 letter identifier, plus field unit number, plus input or
output identity.
Commands available:
- Toggle interlocks between On and Off. Note that interlocks can only be turned on
provided that some interlocks have been defined.
