Reference code comparison
The following modules can be used to support reference code comparison.
The reference code function compares the currently decoded read results with one or more stored compari-
son patterns. The function is split into two comparison units which can be configured independently of each
other.
8.14.1 Module 81 – Reference code comparator 1
PROFINET-IO module identifier
Module ID: 1081
