[EthercatDevice_DmpHID_Generic]
Description
Read the Ratio value of the MPG for the EtherCAT slave device.
Derived Class:
| Class Name | Vendor ID | Product Code | UART | Keypad | LCM | MPG |
| EthercatDevice_QECR11HU1S | 0x00000bc3 | 0x0086d404 | O | O | ||
| EthercatDevice_QECR11HU9S | 0x00000bc3 | 0x0086d402 | O | O | O | O |
| EthercatDevice_QECR00HU9S | 0x00000bc3 | 0x0086d401 | O | O | O | O |
Syntax
int mpgReadRatio();
Parameters
None.
Returns
Return the Ratio value.
- 0: 1x.
- 1: 10x.
- 2: 100x.
If the return value is smaller than 0, it means an error code.
Comment
This function must be called after a successful execution of EthercatMaster::start() and before EthercatMaster::stop(). This function is non-blocking and can be called within the callback functions.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR11HU9S slave;
void CyclicCallback() {
slave.update();
}
void setup() {
Serial.begin(115200);
master.begin();
slave.attach(0, master);
master.attachCyclicCallback(CyclicCallback);
master.start();
}
void loop() {
Serial.print("Ratio: ");
Serial.println(slave.mpgReadRatio());
delay(1000);
