Description of Functions
9.3.7
Request Application Data (Job No. 18)
Overview
A selection of up to four display data items whose values can be read out
with "read application data" (see Section 9.3.13).
Code table:
The code should be entered in CODE_AP1...AP4.
These values are always updated in the module cycle.
The selection is stored on the FM, i.e. you only need to make the selection
once and read the correponding values cyclically (job no. 105).
