Defining communication areas
Communication areas must be defined in the PLC in order that special tasks

Defining the communication area for alarm messages:
• Double click on "Area Pointers" in the project window
• Select the "Alarm Messages" option from "Available Types"
• Click on "OK"
• Select the PLC to be used from the "PLC" options
• Define the other settings for alarm messages.
• Click on "OK"
Setup this data area in the PLC program too.
