Language Objects and Generic IODDT Applicable to Communication Protocols
Original instructions
Introduction
The Modicon X80 modules have an associated IODDT of type T_GEN_MOD.
Observations
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.
Some bits are not used.
