The diagnostic data of each DP slave is defined by EN 50 170Volume 2, PROFIBUS.Input parameter RECORD determines the target area where the data read from the slaveis saved after it has been transferred without error. The read operation is started wheninput parameter REQ is set to 1.The following table contains information about the principal structure of the slave diag-nosis.For additional information please refer to the manuals for the DP slaves that you areusing.Byte Description0 station status 11 station status 22 station status 33 master-station number4 manufacturer code (high byte)5 manufacturer code (low byte)6 ... additional slave-specific diagnosticsThe SFC 13 is executed as asynchronous SFC, i.e. it can be active for multiple SFC-calls.
