6.2 Program Example for Reading the Inverter Status
Write a program as explained below to read the inverter status from the master station buffer memory:
The following program reads the inverter status of station 1 to M0-M7:
FROM 0000

Reads the remote input data of buffer
memory to D0.
Stores b0-b7 (status) in D0 to M0-M7.
