Chapter 7 Exclusive Functions for iS7 Inverter Control/Monitoring
7-15
7.2.3 Monitoring (PLC Option Í Inverter)
(1) Using inverter digital input points as the digital input points of PLC option
Maximum 11 digital input points of inverter (with basic 10 points mounted: 8 points, with 10 extension points:
basic 10 + 3 points) can be used as the digital input points of PLC option. Or, the status (0 or 1) of inverter
digital input points can be used simply for monitoring function.
▶ Common area of inverter
Referring to the parameters (exclusively for monitoring) of inverter common area in the “App. 4-2, page 4,
Appendix,” the addresses of the common area of the inverter digital input status are as follows.
