Scripting in 800xA
How scripting is done in 800xA? My target is to change modes of several PID blocks to Manual and set output to Zero on a single click.

It is not good idea to give commands to PIDs by 800xA HMI script. It is more reliable solution to build this function in the logic of Conrol system CPU (PLC/DCS). For example set all concerned PIDs to Auto in the first step of sequence.
If HMI script is only one solution you can use BatchWrite or SequentialWrite functions in PG2 graphic to set several items by one button click.
