Response Response monitoring enables you to define how the DP slave reacts to a DP master
monitoring for error or a break in the data traffic on the bus.
slaves
If the DP slave is not addressed within the response monitoring time you define, the
slave goes to safe condition (all outputs are set to "0").
If you set response monitoring to "Yes" (by checking the box), the setting applies to
all DP slaves assigned to the DP master. Note, however, that you can switch off
response monitoring for individual DP slaves, for example during initial operation
(switch in the "Slave parameters" dialog box).

Danger
If you switch off response monitoring, there is a possibility that
the outputs of a particular slave may not be set to "0" if an error
occurs.
Consequently, we strongly recommend that response
monitoring be switched off only for initial operation.
