Auto-Clear

The DPM1 cyclically sends its local status in a configurable time interval to all DP slave devices assigned to it with a multicast command.

Auto-Clear is a system response when an error occurs in the data transfer phase of the DPM1. Such an error can be the failure of a DP slave device, for example. If Auto-Clear mode is enabled, the DPM1 assigns safe values to the outputs of all associated DP slave devices as soon as a DP slave device is no longer ready for user data transfer.

If Auto-Clear mode is not enabled, the DPM1 remains in Operate state even in the event of an error and it is up to the user to determine the system response.
