Reading the current configuration of an EAP device

If applicable, the current configuration can be read from the active EAP device (see section Reading an active device configuration). A prerequisite is that the EAP device has already been activated with the aid of TwinCAT 3. Otherwise no instance of the EAP device exists, and the EAP device would not be accessible. In addition, an ADS/AMS route must be entered from the PC, on which the TwinCAT EAP Configurator runs, to the machine, on which the TwinCAT project Measuring or Operating runs.

When the current configuration is read, the previously imported device configuration is discarded and replaced by the read configuration. The imported symbol information remains unchanged.

Avoiding the import of an EDC file Alternatively, the import of an EDC file can be omitted. However, in this case no symbol information is available, and the appropriate Local AoE Net ID of the TwinCAT EAP device must be entered under the properties in the Properties window of the EAP device object, before the configuration of the TwinCAT EAP device can be read.
