282 Parameters
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.
0b0000
0b0000...0b1111 Checksum control word. 1 = 1
96.68 Actual checksum A Displays the actual parameter configuration checksum A.
The checksum A is generated and updated whenever an
action is selected in 96.54 Checksum action and 96.55
Checksum control word, bit 8 = 1 (Approved checksum A)
The set of parameters for checksum A calculation does
not include fieldbus settings parameters.
