Addressing of language objects associated with discrete in-rack I/O modules
Presentation
Illustration
Addressing of bit and word objects is defined in Shared specific applications (See
Addressing input/output module objects in rack, p. 31).
This page describes the specific features linked to the discrete in-rack I/O modules.

When the rack number (x) is other than 0, the position (y) has a 2 digit code: 00 to 14; however, if the rack number (x) = 0, the non-meaningful zeros are deleted (from the left) from "y" ("x" does not appear and "y" takes 1 digit for values of less than 9).

MOD
MOD: channel reserved for management of the module and the parameters shared by all channels.
0 to 3 or
ERR
ERR: indicates a module or channel fault.

Indexable discrete I/O objects.
Presentation All the discrete module I/O objects are indexable (apart from the TSX DMY 28RFK and TBX DMS 16P22 I/O module objects).
For in-rack TSX and TBX modules, indexing of %I and %Q objects is done independently.
For Momentum modules, indexing for %I objects continues for %Q objects of the same module.
