As per drawing there are two SAS IED 61850 port should be available in the relay. One is main port and other one is redundant port.
But the relay dose n't have the redundant port.
The new card was ordered with PRP redundant port.
The new card was changed but both port was not communicated with SAS and relay shows following error.
Relay was not communicate with SAS .
Manufacturer send a firmware for the new card. The firm ware is a " . bat" each relay have individual firmware.
Initially this firm ware not up load in to relay and its need to switch off fire wall and Auti vireos.
Then firmware was updated in the relay and Redundant PRP status shows " OK".
Then SAS engineer check the IP address in the relay and it was not mach.
Finally he correct IP address and every think get normal and relay communicated with SAS.
