Limited selection of function blocks
The following inputs and outputs are only supported by certain Festo motor controllers. All other inputs and
outputs are present in all CoDeSys function blocks ..._PRM_DIAG depending on the type of the motor
controller.
Input/output Type Motor controller
Warning BOOL CMMP_AS
CMMP_AS_CAM
Composition of the field structure of the diagnostic buffer
DiagBuff ARRAY [1..32] OF FHPP_PRM_DIAGMESSAGE;
TYPE FHPP_PRM_DIAGMESSAGE :
STRUCT
DiagEvent : DINT ; (* diagnostic event PNU 200 / PNU 210 *)
DiagMsgNumber : DINT ; (* fault number PNU201 / PNU 211 *)
DiagTimeStamp: : TOD ; (* timestamp of the diagnostic message *)
DiagMsgDescription : STRING; (* description of the diagnostic
message *)
END_STRUCT
ENT_TYPE
Since the structure FHPP_PRM_DIAGMESSAGE is universally valid, entries such as DiagEvent
and DiagTimeStamp are not supported by all drives. The size of the diagnostic buffer is also
dependent on the relevant motor controller.
Function block xxx_PRM_DIRMP
The xxx_PRM_DIRMP block writes or reads the dynamic values for direct mode (position control).
