Status Flags
-
This is a group of flags indicating test status.
11.2.2.4.2.1 Status Flags Bitmask
This is identical to table 11D (page 62).
Bits 0-2 are so that external equipment (for example LASPAC-View or a PLC/MMI) can display, update
and log results intelligently
Bits 3 and 4 can be used to monitor the test progress.
Bits 5-10 are used to generate alarms. Depending on the selected alarm mode, they operate the alarm
relay output(s). But they can also be monitored directly by a PLC/MMI program and used to drive
indicators, for example.
Bit 11 is used internally to detect that the LPM is being controlled by Modbus (from a PLC or by
LASPAC-View).
Finally bits 12-14 reflect the state of the LPM
“start signal” input and alarm output relays.
