Issue:
Can the  M221 timer preset value be changed when the PLC is running.

Product line:
M221, Ecostruxure Machine Basic, SoMachine Basic

Resolution:
Yes the M221 timer preset can be changed at runtime.
Each timer has a timer preset object %TMi.P
To change the value of the preset object you need to write the value to a memory word(%MWx).
Then you need to move the memory word value to the timer preset object. You do this using an Operation block (%TMi.P:=%MWx)
