For this to be possible, direct communications only take place
with one single configured station (CP address). This station then
forwards data packets to the desired rack/slot.
If you use this mode, the following settings must be configured
on the web interface configuration page:
• “RFC Multi Computing with TSAP” must be disabled (OFF)
• “RFC Routing over CP with TSAP” must be enabled (ON)
• The numeric values for the rack/slot combination being used
must be entered into the "Rack" and "Slot" fields
In this case, it is necessary to make sure that all CP/CPU combina-
tions are working with the same rack/slot value pairs (stored on
the web interface) (in the example above: Rack 0; Slot 2).
Experience has shown that CP-CPU routing works well with “0/2”
rack/slot combinations when using CPUs from the 300 series.
In addition, the corresponding parameters in the communica-
tions software (SCADA application) need to be configured ac-
cordingly. The "Remote TSAP -> Slot numbers" must match those of
the corresponding CP address (in the example above: 5, 6, and 7).
If the CP modules are not
sending the required bus
parameter
frames, the
“Single Master” function
must be enabled on the
NETLink web interface.
