Overview

Type:	Function
Available as of:	V1.0.4.0

Task

Function for setting a command within a command table that shall be processed together with the previous command.

Description

The function helps to initialize tables easily.

The function writes the value of iq_udiStepIndex to the iq_iStepIndex variable and adds 1. The step field index of the table is assigned with this variable.

Only iq_diStep is entered again into the iq_iStep variable. With the same step within a table, the FB_ModuleController recognizes that this command should be sent to the related module(s) in the same cycle as the previous command.
