At a Glance
This section describes T_DIS_IN_STD type IODDT Explicit Object Exchange that applies to discrete input and reflex input modules. It regroups word type objects, which bits have a particular meaning. These objects are explained in detail below.
Example of declaring a variable:
IODDT_VAR1 of type T_DIS_INT_STD.
NOTE: Generally, bit meaning is provided for state 1 of that bit. In specific cases each bit state is explained.
NOTE: Not all bits are used.
