Section: Overview
Here you can set the parameters, which will be displayed in the bus overview.
Up to 20 parameters can be set. The available parameters are shown right.
Section: Bus
The protocol displayed here is automatically determined when the WIB scans
the bus for units. Only change it in exceptional cases according to the control-
ler type and upon consultation of the Stulz support:
C7000: SCP BMS
C6000: SDC
C5000: SDC
C1002: SDC
C1010/C2020: SCP BMS or SDC (depending on the C1010/C2020 soft-
ware version and the parameters adjusted there)
The adjustable predelay is a delay which is inserted before a command is sent
to an A/C unit and serves to eliminate interference in bus communication when
different controller types participate (e.g. C5000 and C7000, in this case the
predelay must be set for the unit with the C7000). However, a predelay decel-
erates bus communication.
The adjustable postdelay is a pause after the response of the unit/controller
has been received. During this time the bus is not used. This parameter serves
as the predelay to eliminate interference in bus communication. For the individ-
ual case it must be tested which setting is more effective.
In another box you can determine the maximum number of datapoints which is
transmitted in a command. The value which is displayed here has been adjust-
ed by the WIB due to the detected controller type according to the buffer size
of the controller. In case of hardware modifications of existing controllers you
have the possibility to manually adapt the value.
Meaning of the possibles settings "use addressed request":
No:
only data package requests are raised. This is appropriate for C7000 IOCs with software version
IOC-V3.xx and older.
Yes:
data package requests or addressed requests are raised (automatic selection of the best procedure
at each request). Only for C7000 IOCs with software version IOC-V4.00 and newer.
Always: only addressed requests are raised. this is necessary for C1010/C2020 controllers with SCP BMS
protocol.
This parameter is not relevant for the protocol "SDC" (C6000 and older controllers or C1010 with older
software).
The other menu items (zone, overload start etc.) have already been explained in the context with the zone
configuration.
