Function Codes
An I/O block prevents the use of any I/O channel function
codes it does not support. For example, a DOT-100 block sup-
ports 16 digital output channels, and therefore will only allow
using digital out/channel function codes (FC 225) and addi-
tionally only channels one through 16.

NOTES :
1. In normal mode this is redundant I/O deviation limit. In override mode this is override deviation
limit. In simulation mode this is simulation deviation limit.
2. Readback A/D conversion accuracy for analog outputs.
