Command: Scan for Devices

Introduction

Function: The command establishes a temporary connection to the hardware and detects the devices in the network. Then you can apply the scanned devices into the device tree of your project.

Call: “Project” menu; context menu of a device object in the device tree

Requirement: The communication settings to the controller are correct. The gateway and the PLC are started. The device supports the scan function.

The following devices provide the scan function: EtherCAT Master, EtherNet/IP Scanner (IEC), Sercos Master, CANopen Manager, CANopen Manager SIL2, Profinet Controller, and Profibus DP Master.

You can perform the device scan immediately if the scan function is permanently implemented in the PLC. When the scan function is implemented in a library, you have to log in only one time to download the library to the controller.

The command applies to the master controller selected in the device tree. For example, an already inserted PROFINET Controller can be selected and the command used to determine the I/O devices and I/O modules assigned to it.

After performing the scan operation, the “Scan Devices” dialog opens and displays the scanned devices.
