[EthercatDevice_DmpAIQ_Generic]

Description

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

Derived Class:

Syntax

int currentWrite(int ch, double current);

Parameters

• [in] int ch
  The specified analog output channel on the EtherCAT slave device.
• [in] double current
  The desired output current, in amperes (A).

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.currentWrite(0, 0.02);
  delay(1000);
  slave.currentWrite(0, 0);
  delay(1000);
  slave.currentWrite(0, 0.01);
  delay(1000);
  slave.currentWrite(0, 0);
  delay(1000);
}
