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.
