ADS_over_Ethercat¶

Function blocks for AoE (ADS over EtherCAT)

Example:

This example reads the scanning distance parameter from a Sick WTB12C-3P2413 IO-Link Device connected to the second port of a Beckhoff EKL6224 EtherCAT IO-Link gateway.

PROGRAM PLC_PRG
VAR
  iolinkread : ETC_ADS_IoLinkRead;
  xRead : BOOL;
  wScanningDistance: WORD;
END_VAR
EtherCAT_Master();
IF EtherCAT_Master.xConfigFinished THEN
  iolinkread(xExecute := xRead, usiCom := 1, uiDevice := EL6224.PhysSlaveAddr, udiTimeout := 500, usiPort := 1,
          uiIndex := 144, usiSubIndex := 0, pbyData := ADR(wScanningDistance), udiSize := SIZEOF(wScanningDistance));
  // usiPort 1: second port of gateway
  // uiIndex 144: scanning dIstance
  IF iolinkread.xDone THEN
      // Todo: add handling for data
      xRead := FALSE;
  END_IF
  IF iolinkread.xError THEN
      // Todo: add Error handling
      xRead := FALSE;
  END_IF
END_IF
