Addressed Mode (RFC1006)
Figure 15: Addressed Mode
With the addressed mode it is possible to access several CPUs which are
at the same MPI/PROFIBUS. If this mode is used you have to configure
the following in the web interface:
•
»Rack/Slot Mode« has to be off (»OFF«)
•
In the application's RFC1006 driver you have to indicate the bus
address (rack and slot number) of the CPU which should be
accessed.
Example:
If you want to communicate with the PLC number 2:
Rack 0, Slot 2.
If you want to communicate with the PLC number 49:
Rack 1, Slot 17.
A conversion table for the rack and slot numbers is in the chapter
»Appendix«
Parametrization tools without a rack and slot fields mostly have a
parametrization field for the »Remote TSAP«. Normally, this is 2 bytes
long and is shown in hexadecimal. The field where only 1 byte is used
can be parametrized as follows:
ACCON-NetLink-PRO compact
26

Do you have a question about the ACCON-NetLink-PRO and is the answer not in the manual?
