Inverter Interface
SECTION 5
5-1
Inverter interface
The communication between the PLC and the Inverter is performed by:
•
Inverter functionality mapped in IR (section 5-2)
•
Inverter functionality mapped in DM (section 5-3)
•
Through the Transfer command (section 5-4)
5-2
I/O Allocation IR
The contents of the IR area is refreshed and updated with each scan.
