Configure HSP Connection
The safety scanner closes the HSP connection whenever either an HSP
error occurs or the safety scanner diagnostic reports an error.
Individual DeviceNet safety or standard connection errors do not
cause the HSP connection to close. In the case of a faulted DeviceNet
connection, any input data associated with that connection is forced
to zero before being transmitted to the GuardPLC controller over HSP.
Your GuardPLC application logic can control the operation of the HSP
connection, by writing a value to the signal associated with the HSP
Connection Control Word.
To connect a signal to the HSP Connection Control Word, right-click
on your HSP protocol in the RSLogix Guard PLUS! Hardware
Management window and choose Connect Signals>HSP Data.
The following table describes the possible mode settings for the HSP
connection.
