Details of T_DIS_IN_FIP_STD-Type IODDT Explicit Exchange Objects
(Original Document)
At a Glance
This section presents T_DIS_IN_FIP_STD-type IODDT explicit exchange objects applicable to input modules and the inputs of mixed Discrete modules (TBX, IP67). It includes the word type objects whose bits have a specific meaning. These objects are described in detail below.
Example of a declaration of a variable:
IODDT_VAR1 of the T_DIS_IN_FIP_STD type.
NOTE: In general, the meaning of the bits is given for bit status 1. In specific cases an explanation is given for each status of the bit.
NOTE: Not all bits are used.
