Resetting a device

In the TwinCAT configuration tree each configured fieldbus is allocated to a "device". A "device" may be an actual hardware object such as a PCI_Fieldbus master card (e.g. Lightbus card), or it may be a virtual device, such as an Ethernet or EtherCAT interface.

If errors occur in the subsidiary fieldbus during the configuration phase (errors will be displayed in the logger window of the System Manager, for example), the device may have to be reset after acknowledging the errors. Generally this is achieved through a complete restart of TwinCAT in Run or Config mode, which affects all connected devices.

In some cases a selective reset of an individual device may be desirable. This is achieved by right-clicking on the device in the configuration tree, see Fig. Selective reset of a configured device.

The "logger window" of the System Manager can be displayed for monitoring purposes.

Depending on the cause of the fault the device may have to be reset several times.
