  • Create a "Standard project” and select CODESYS Control Win V3 as the device.
  • Define the target system by means of Network scan.




  • Activate the Diagnosis for devices.




  • Insert an EtherCat Master Ethernet adapter and specify the interface to be used.

    If a target system has not been defined yet, then the error message "Gateway not configured" is displayed.





  • Insert a slave below the EtherCat Master or scan the bus.




  • Edit the PLC_PRG POU as follows:

    Declaration

    VAR
    xDisable        : BOOL;
    xEnable         : BOOL;
    xReconfigure    : BOOL;
    itfNodeSlave    : DED.INode;
    fbReconfigure   : DED.Reconfigure;
	eState          : IoDrvEthercatLib.ETC_SLAVE_STATE;
END_VAR

    Implementation

    itfNodeSlave := EK1100;

IF xDisable THEN
    xDisable := FALSE;
    itfNodeSlave.Enable := FALSE;
    xReconfigure := TRUE;
END_IF

IF xEnable THEN
    xEnable := FALSE;
    itfNodeSlave.Enable := TRUE; 
    xReconfigure := TRUE;
END_IF

fbReconfigure(xExecute := xReconfigure, itfNode := EtherCAT_Master);

IF fbReconfigure.xDone THEN
    xReconfigure := FALSE;
END_IF

EK1100(); // Necessary for the status to be updated
eState := EK1100.wState;


  • Start the project and test the functionality by deactivating and activating the slave.
