Details of the IODDT's explicit exchange objects of type T_COUNT

At a Glance

This part shows the IODDT's implicit exchange objects of type T_COUNT_ACQ which applies to the three modules TSX CTY 2A/4A/2C. It brings together word-type objects whose bits have a special meaning. This objects are described in detail below.

Example of declaration of a variable: IODDT_VAR1 of type T_COUNT_ACQ

Notes

Generally speaking, the meaning of the bits is given for state 1 of this bit. In specific cases, each state of the bit is explained.
Not all of the bits are used.

Explicit exchange operation indicators: EXCH_STS

The table below shows the meanings of exchange control bits of the channel EXCH_STS (%MWr.m.c.0).
