Thanks to S7 automation,
To put it in soccer terms; the assist is just as important as the goal.

Kind regards,

Hi samtj,

what S7 Automation means is, Enable memory clock on your cpu (properties of cpu), create a tag in your hmi linked to a memory clock bit that pulses every second (memory bit 5 pulses every second). Then select properties of that tag in your hmi and go to events, now add the script you want executed on value change.

Kind regards,

Jens

 Hello!

it can be a problem if you have 100 tags from the plc, and the acquisition time is 100ms in every tags? The profinet can handle with this amount of data?

Sorry for my english.

Kind regards,
