EthercatDevice_DmpAIQ.voltageWrite()

[EthercatDevice_DmpAIQ_Generic]

Description

Write a voltage value to the specified analog output channel on the EtherCAT slave device. This function is used to specify that the channel is configured for Voltage Mode.

Derived Class:

Syntax

int voltageWrite(int ch, double voltage);

Parameters

• [in] int ch
  The specified analog output channel on the EtherCAT slave device.
• [in] double voltage
  The desired output voltage, in volts (V).

Return Value

Return an error code. If the returned value is zero, it indicates a successful execution of this function.

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_QECR11A44S slave;

void setup() {
  master.begin();
  slave.attach(0, master);
  master.start();
}

void loop() {
  slave.voltageWrite(0, 10.0);
  delay(1000);
  slave.voltageWrite(0, 0);
  delay(1000);
  slave.voltageWrite(0, -10.0);
  delay(1000);
  slave.voltageWrite(0, 0);
  delay(1000);
}
