This script is called via a buttonon the screen ("Click") and now I am needing to call this scriptfrom a PLC.I have created an IO tag and that taghas the script called via the event"Change Value" , so the PLC will request the stamp by setting the tag to "1" and the tag will be set back to "0" at the end of the script. This works but I get dual stamp due to the "Change Value" function of the tag. The tag calls the script when itgoes true and when it goesfalse. Is there a way to scedule a Job or any other means to call a script from the PLC without using the "Change Value" function? Thanks in advance! -thefro
