Task integration (call)
The _POSMOA_rwParameter function block must be called cyclically in the
BackgroundTask or in the TimerInterruptTask. Calling in the SystemInterruptTask is not
permitted. Calling the function block in synchronous tasks (e.g. IPOSynchronousTask) is not
recommended for runtime reasons.
Fault messages
The TRUE value at the error output parameter indicates a parameterization error. The
errorID output parameter provides more detailed information on the parameterization error that
has occurred or has been signaled by POSMO A. Parameterization errors do not need to be
acknowledged. Changed parameters (e.g. ramp-up time) can be transferred again.

Function block _POSMOA_rwAllParameter
Task
The _POSMOA_rwAllParameter function block enables reading and writing of the parameter
block of the connected SIMODRIVE POSMO A.
The data to be read or written are saved in a variable created by the user with the
Struct_POSMOA_params data structure when the associated function block instance is
called.
The following parameters are read/written with this function block:
Parameter numbers Read from POSMO A Write to POSMO A
(positioning mode)
Write to POSMO A
(speed-controlled mode)
