I am running Codesys ControlWinV3x64 (Patch 4) on my laptop for demonstration purposes but I am unable to get connection to the EtherCAT master and slave device.
This is the process that I have followed:
Installed NPCap.
Added the xml file for the SMC slave device to the Device Repository.
Activated Control Win SysTray x64 and selected Start PLC.
Scanned the network for the local device (my laptop).
Added an EtherCAT master to the project and scanned the EtherCAT master for the Network and then selected the correct network.
Selected "Scan for devices" to identify the connected I/O.
Add the SMC EtherCAT slave manually because I was unable to scan it in.
Selected "Scan for devices".
I have followed the steps described above but I can't scan in the EtherCAT slave or connect to it.
I thought this situation was unique to the EtherCAT slave but I have also tried the same for an EtherNet/IP slave using the Ethernet Adaptor and EtherNet/IP scanner and I am also unable to scan in the device or activate the EtherNet/IP network.
Any assistance will be appreciated.
