Simple Scripting Aspect 800xA/Compact HMI 800
I would like to find a way to use scripting in Compact HMI 800 (800xA).
I can see that there is an aspect named "Simple Scripting Aspect".
Does anyone know if it is possible to use this aspect to:
1 - Read an OPC tag value (integer)
2 - Process the integer value and then output a text to the Graphics Editor (textbox or similar)
3 - The script should be executed continiously
The reason for not using Express variables in this case is that I need to store "last value" of the OPC tag, evaluate if value has changed and then output a string from there.
I'm quite familiar with VBscripting but need help with the interface between
OPC tag-> VBScript -> Graphics Editor.
Thanks in advance!
