General information
Diagnosed errors are displayed with regard to the error type via local diag‐
nostic displays and/or transferred as diagnostic messages to the control.
Diagnostic messages are read out via communication objects, also called
PDI objects. Access these objects using the “Mapping procedure“ via Sercos
P-parameters described in the data sheet "Rexroth IndraControl S20 Bus
Coupler for Sercos" (R911342782).
For further information on the communication objects and general
