5 Functional Mechanisms of this Application
5.2 Parameter access functionality
Structure
FB "Parameter" consists of two parts:

A step sequence which controls the sequence of the parameter access
(networks 1 to 22).

The calls of the system functions "Write data set" or
"Read data set" (networks 23 to 25).
Step sequence
The individual steps of FB "Parameters" are represented in the following graphic.
The possible transitions between the individual steps are also displayed there.

State

If START is false, all the transmission-related, block-
internal signals and output signals are deleted.

It is waited for a rising edge of the "Start" signal.

If it is detected, "busy" will be set and step 1 activated.
