No. Terminal Name Function description
MOD2
Modbus2 communication
indicator
When communication with Internet of Things and MIB/remote
monitoring board is normal, this indicator is on (green).
COP
CAN1 communication
indicator
When communication between the MCB and the CTB is normal,
this indicator is on (green).
HOP
Modbus1 communication
indicator
When communication between the MCB and the HCB is normal,
this indicator is on (green).
CAN2
Group control
communication indicator
This indicator is steady on (green) when communication for
parallel/group control is normal, and blinks when the running in
parallel/group control mode is normal.
232
Serial communication
indicator
This indicator is on (green) when communication with the host
computer or MIB/remote monitoring board is normal.
X1 to X24
Low voltage input signal
indicator
This indicator is on when the external input is active.
X5 to X28
High voltage input signal
indicator
This indicator is on when the external input is active.
Y1 to Y6 Output signal indicator This indicator is on when the system output is active.
