DESCRIPTION OF MODBUS REGISTERS
40002 / 40003: FIRMWARE
Two read-only registers, containing the firmware version.
40007: NODE ID
Contains the Modbus address of the device; the values allowed are from 1 to 245 decimal.
This value must match the Modbus address of the connected Modbus device (data source).
Default value: 1 Decimal (01 Hex). INIT value: 245 Decimal (F5 Hex).
40011: SYSTEM FLAGS
Contains the enable bits and system event identifiers. The following parameters are configurable:
Watchdog Event Enable: this bit enables the Watchdog Event (0=Watchdog Disabled, 1 =Watchdog Enabled). If the Watchdog
is enabled and the Watchdog Timer (configured in register 40013) expires before this device receives a Modbus command, the
green PWR LED blinks and the Watchdog Event bit is set to 1. This bit must be set in logic on power up.
Watchdog Event: this bit is set to 1 when the Watchdog Timer expires before this device receives a Modbus command. This bit must
be reset manually after a Watchdog event.
Power Up Event: this bit is forced to 1 at each time power is applied to the device to indicate that the device has been switched off
or reset. With the setting of this bit as 0 (by the user) and checking its state, it is possible to know if a reset of the device has occurred
(0 = reset not occurred; 1 = reset occurred). This bit must be reset manually.
