10.1.2 Process data mapping
n = offset of input data; depending on extension of station and the corresponding fieldbus.
m = Offset of process output data; depending on extension of station and the corresponding fieldbus.

NOTE
With PROFIBUS, PROFINET and CANopen, the I/O data of this module is localized within the
proce
ss data of the whole station via the hardware configuration tool of the fieldbus master.
For DeviceNet, EtherNet/IP and Modbus TCP a detailed mapping table can be created with
the TURCK configuration tool I/O-ASSISTANT V3 (PACTware + BL67-DTM).
