DIO#.INV

Description

Sets or gets the polarity of a bi-directional I/O when configured as a digital input (see DIO#.DIR).

Value	Description
0 - Active high	The digital input state is 1 when voltage is applied to the IO pin
1 - Active low	The digital input state is 1 when voltage is removed from the IO pin

Examples

Usage

When DIO#.DIR = 0 (input) then the corresponding DIO#.INV can be set to change the polarity of the input signal.

Code

--> DIO1.DIR 0

With 24V on DIO1:

--> DIO1.INV 0 //Active high
--> DIO1.STATE
1
--> DIO1.INV 1 //Active low
--> DIO1.STATE
0

With 0V on DIO1:

--> DIO1.INV 0 //Active high
--> DIO1.STATE
0
--> DIO1.INV 1 //Active low
--> DIO1.STATE
1

Fieldbus Information

EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs CoE and CANopen
