Presentation of Language Objects of the Discrete Application Function Associated with IP67 Sealed Modules on a Fipio Bus

General

modules have different associated s.

The IODDTs are predefined by the manufacturer. They contain input/output language objects belonging to a channel of an application-specific module.

NOTE: IODDT variables may be created in two ways:

There are several types of IODDT for remote sealed input/output modules on a bus:

Likewise, there are several IODDT types for the following modules:

Language Object Types

Each IODDT contains a group of language objects that are used to control them and check their operation.

There are two types of language objects:

Implicit exchange objects, which are automatically exchanged on each cycle of the task associated with the module,
Explicit exchange objects, which are exchanged when requested to do so by the project, using explicit exchange instructions.

Implicit exchanges concern the module inputs/outputs: process value results, information and commands.

Explicit exchanges are used for setting module parameters and for diagnostics.
