DIO#.FILTER
Description
Gets or sets the digital input filter when specified channel is configured as a digital input (see DIO#.DIR). The digital filter blocks input changes (rising or falling edges) until the minimum pulse width is exceeded. The +/- tolerance listed is the sample period (uncertainty) of the filter.
Value | Description | Min PulseWhen the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated Width | Typical Use |
---|---|---|---|

Usage
When DIO#.DIR = 0 (input) then the corresponding DIO#.FILTER can be set to adjust the filter of the input value.
Code
--> DI01.DIR 0 --> DIO1.FILTER 0 --> DIO1.FILTER 1

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. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. Mappable |

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.FILTER | 0x368A | 0x3 | USINT | - | - | RW | False |
