DIO#.INV
Description
Sets or gets the polarity of a bi-directional IO 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
Context

Fieldbus Information
FieldbusA Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design | Parameter | Index | Sub-Index | Data Type | Float Scale | Units | Access | PDOPDO is a type of protocol frame used in some fieldbuses.

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 | DIO1.INV | 0x368A | 0x2 | USINT | - | - | RW | False |
