Function Block FB 156 (PER:WPA)
9.2.1 Function Description
The function block “parameterize position decoder” supplies the module with the initial and final
track
setpoints for both channels including the zero shift. If necessary the interrupt identifier bits
are set.
The data to be transferred is stored in a user data block. The required data must be entered there
by the user prior to calling the function block.
Prior to parameter assignment, the data on the module is deleted. The firmware contents are read
and entered into the data block.
In the S5–115U, the function block is usually called by organization block OB20 (or OB21 pro-
grammable controller S5–115U) if there is a cold restart.
Function
Transfer of the specified setpoints from the user data block to the digital position decoder module
1P 241.
