Coil description
All the following coils are found at zero address.
Address 00001: Watchdog enable
Default value: OFF (Disabled watchdog)
Set this coil to enable Modbus watchdog.
Warning: this coil is not stored in the permanent memory of the device. If it is set to ON the
next time it is switched on, it will return to OFF (Default value)
Address 00002: Watchdog event
If coil 0 has been activated, a set value indicates that the device has not received commands
within the set watchdog time value (register 40063). This coil can be cleared to reset the
event. If the coil is forced high, a watchdog event is simulated together with its alarm
condition.
1 = Alarm
0 = No event
For example, this coil can be used by the SCADA software to monitor the communication.
Address 00003: Power-UP event
This coil is set after power-on event. It must be manually cleared to monitor a reset event.
1 = Reset
0 = No reset
Address 00004: Transmission and reception LED status[R/W]
Default value: OFF (LED OFF)
Clear this register for these LEDs activation; set this register to deactivate these LEDs. This
value is saved into non-volatile memory.
Address 00005: PWR LED status[R/W]
Default value: OFF (LED OFF)
Clear this register for this LED activation; set this register to deactivate this LED. This value
is saved into non-volatile memory.
Attention: if both coils 4 and 5 are set, it would be possible to save energy. This can be
particularly useful at power on, when several devices are connected and the current supplied
is limited.
