The data available 1 SSR3 register is located by default at address 40130. The bit values in the SSR3 register are Modbus client dependent.
Bits 0 and 1 are set to "1" as long as the client in question has not read out the available Modbus event or fault records.
Bit 4 is set to "1" if any momentary bit has been updated in the Modbus memory map. The bit is reset when the client reads the register.
Bit 5 is set to "1" if any MCD bit has been set in the Modbus memory map. The bit is reset when the client reads the register.
Bit 6 is set to "1" to indicate the device restart. The bit is reset when the client reads this register.
Bit 8 is set to "1" when an event record has been loaded into registers 49252...49262. The bit is reset when the client writes the reset code 4 to the event record selection register 49251.
Bit 9 is set to "1" when a fault record has been loaded into registers starting from 49402. The bit is reset when the client writes the reset code 4 to the fault record selection register 49401.
