Parameterization of the Onboard I/O for PM564¶
The 2 analog onboard inputs can be configured as 2 digital onboard inputs, so the maximal digital inputs number is 8. The input and output channels can be provided as WORD, BYTE and BOOL.
Double-click on I/O (onboard IOs) to open the DI+6DO+2AI+1AO configuration in the editor window:
The 6DI+6DO+2AI+1AO onboard I/Os support the following channel functions:
| Onboard I/O Type | Channel Function | Max. Number | Channel Name |
|---|---|---|---|
| Digital onboard I/O | Digital Input | 8 | Digital input channel 0..5 Analog input channel AI0..AI1 * |
| Fast counter | 2 | Input channel 0, 1 | |
| Interrupt input | 4 | Input channel 0..3 | |
| Digital output | 5 | Output channel 0..5 | |
| PWM output | 2 | Output channel 2..3 | |
| Analog onboard I/O | Analog input | 2 | Input channel AI0..AI1 * |
| Analog output | 1 | Output channel AO0 |
* These 2 analog inputs can be configured as 2 digital inputs
Same as PM554, the Processor Module PM564 has a maximum of 8 digital onboard inputs and 6 digital onboard outputs. The channel parameters for onboard digital I/Os are the same as those of PM554 and can be found in table onboard I/Os for PM554 Parameterization of the Onboard I/Os for PM55x-xP. Analog input channels AI0&AI1 on PM564 are for digital input channels 5&7 on PM554.
| Onboard I/O Type | Parameter | Channel Name | Default Value | Value | Meaning |
|---|---|---|---|---|---|
| Analog inputs | Input delay digital input | Channel AI0&A1 | 8 ms | 0.1 ms | Configure 0.1 ms input delay |
| 1 ms | Configure 1 ms input delay | ||||
| 8 ms | Configure 8 ms input delay | ||||
| 32 ms | Configure 32 ms input delay | ||||
| Channel configuration | Digital input | Digital input | Configure the channel as normal digital input | ||
| Analog input 0..10 V | Configure the channel as 0..10 V analog input | ||||
| Analog outputs | Channel configuration | Channel AO0 | Analog output 0..10 V | Analog output 0..10 V | Configure the channel as 0..10 V analog output |
| Analog output 0..20mA | Configure the channel as 0..20 mA analog output | ||||
| Analog output 4..20 mA | Configure the channel as 4..20 mA analog output |
Note
Default value of channel AI0&AI1 is digital input. The user has to change the configuration parameter to enable the analog input function.
