actual output relay.
In PCM600, only the result of these operations can be checked by right-clicking the
product and selecting Signal Monitoring tool and then navigating to the actual I/O-
board and the binary input in question. The activated output signal is indicated with
a yellow-lit diode. Each BOn_PO is represented by two signals. The first signal in
LHMI is the actual value 1 or 0 of the output, and in PCM600 a lit or dimmed diode.
The second signal is the status Normal or Forced. Forced status is only achieved
when the BO is set to Forced or operated on the LHMI.
