S800 I/O Station Data Scanning

Analog modules will be scanned every fourth I/O scan cycle time except for
AI830/AI830A, AI835, AI843 and AI893 modules which will be scanned every
tenth time.
DI and DO modules will be scanned each I/O scan cycle time.
For example, a non-redundant station with a CI810A, two AO810/AO810V2,
three DI810, two AI810, three DO810, two AI830/AI830A and one DP820 will
give the following I/O scan cycle time:
1 CI810A =>
1*1.40 ms =
1.40
2 AO810/AO810V2 => 2*1.20 ms =
2.40
3 DI810 =>
3*0.43 ms =
1.29
2 AI810 =>
2*3.00 ms =
6.00
3 DO810 =>
2*0.43 ms =
1.29
2 AI830/AI830A =>
2*0.40 ms =
0.80
1 DP820 =>
1*1.72 ms =
1.72
-------------------------------------------------------------
14.9 ms
14.9 ms is not a multiple of 2, so an increase of the value to the nearest multiple of 2
gives 16 ms.
CI810A/CI810B compensation 1.25*16 ms=20 ms.
