Hello,
Give more information about PLC used, HMI and Software...
If you use WINCCFLEXIBLE 2008 or later or TIA WinCC advanced, you can use Script.
For example :
Before, you have to creat into HIM 7 a "target link" toward PLC3.
In PLC7 and PLC3 you must creat data, then in your HIM 7, you creat 2 tags (Linked to the variables created previously): One for PLC 7 and an other for PLC 3.
You creat a script called "Tranfert" for example:
SmartTags("PLC3")=SmartTags("PLC7")
Into tag properties PLC 7=> Events=>Value modification => you call the script created previously "Transfert"
That means, each time PLC7 value change, the script will be executed, and the value PLC7 tag is copied into PLC3 tag..
Soory for my poor english..
Best regards
