The module can be integrated if the gateway firmware is at least Version 1.51.
3.1
Data mapping under PROFIBUS-DP
3.1.1
Process input
The field input data is transferred from the connected SWIRE bus to the XNE-
1SWIRE. The process input data is the data that is transferred by the XNE-1SWIRE
module via a gateway to the PLC. The transfer is carried out in 8-byte format. 4 bits
are reserved for each SWIRE slave.
Tab. 5 Data structure
The data of SWIRE slave 1 is the data of the first physical slave on the SWIRE bus.
The remaining slaves are assigned in consecutive order accordingly. The meaning of
the data of an SWIRE slave depends on the product concerned.
