Parameters 277
96.55 Checksum control word
Bits 8…9 select which comparison(s) are made:
• Bit 8 = 1 (Approved checksum A):
96.68 Actual
checksum A is compared to 96.71 Approved
checksum A
, and/or
• Bit 9 = 1 (Approved checksum A): if
96.69 Actual
checksum B is compared to 96.72 Approved
checksum B
.
Bits 12…13 select approved (reference) checksum
parameter(s) into which the actual checksum(s) from
parameter(s) are copied:
• Bit 12 = 1 (Set approved checksum A): Value of
96.68 Actual checksum A
is copied into
96.71
Approved checksum A
and/or
• Bit 13 = 1 (Set approved checksum B): Value of
96.69 Actual checksum B
copied into
96.72
Approved checksum B
