Introduction
This topic describes the explicit exchange objects of the IODDT of type T_COM_ETYX103 that applies to the modules TSX ETY 4103/PORT/5103 and TSX WMY 100. It includes word-type objects whose bits have a special meaning. These objects are described in detail below.
Example of declaring a variable: IODDT_VAR1 of type T_COM_ETYX103
NOTE: Generally speaking, the meaning of bits is given for state 1 of this bit. In specific cases, each state of the bit is explained.
Also note that not all bits are used.
