Table 14:
16 bit SSR1 register
3.3.7.2
SSR2
The bit values in SSR2 are common for all Modbus clients. The bits give an overview of
the IED's mode. For example, bit 6 is activated if the IED's configured time
synchronization source is lost.
Table 15:
16 bit SSR2 register
3.3.7.3
SSR3
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.
