3.5 Process data assignment
The higher-level controller (PLC) sends 10 process output data words (PO1 ... PO10)
via PROFIBUS. The MOVI-PLC
®
sends 10 process input data words (PI1 ... PI10) to the
higher-level controller . An extension to 32 process data words is possible as an option.
The following figure shows data exchange with 10 process data words:
The position values are specified/returned in [inc.] or in the user-defined units [mm] or
[1/10 mm].

PO3 Axis selection:
•
1 ... 8 for single-axis operation
• 99 for group drive
PO4 Target position with single axis selection in positioning mode "high"
PO5 Target position with single axis selection in positioning mode "low"
PO6 Target position virtual encoder in automatic mode high
PO7 Target position virtual encoder in automatic mode low
