i have problem with respect to faults reporting by hblock output group in gmr system(ge-fanuc 90-70)
FAULTS REPORTED BY H BLOCK GROUP:
1.FOR OPEN CIRCUIT FAULT - ALL 4 BLOCKS ARE NOT REPORTING FAULT TO THE CPU(ONE OR TWO OR THREE BLOCKS ARE REPORTING RANDOMLY,IT IS NOT CONSISTENT WITH ANY BLOCK(A/B/C/D)
2.WHEN I/O FAULT RESET IS INITIATED WITH %M12258 ,FAULT STATUS FROM ONE BLOCK IS CHANGING TO ANOTHER BLOCK IN THE GROUP.(THIS IS ALSO NOT CONSISTENT)
pls. let me know the reason/solution)
