Checking
Relay Status
Use the STA serial port command to view the SEL-787 operational status.
Analog channel dc offset and monitored component status are listed in the
status report depicted in Figure 1.2.
If a communications card with the DeviceNet protocol is present, the status
report depicted in Figure 1.3 applies. If a communications card with Modbus
RTU protocol is present, the status report depicted in Figure 1.2 applies.
