If a PCD7.LR-TRxx device is detected on the Sylk bus and its address is used
by a PCD7.LR-TRxx FBox, the “SYLK bus” FBox sends the configuration to the
wall device. With a PCD7.LR-TR40-xxx, this process is invisible, whereas with a
PCD7.LR-TR42-xxx, “FILE TRANSFER” can be read on the display during config
-
uration.
7.2.2
PCD7.LR-TR40-xxx wall device without LC display
An FBox is available for the PCD7.LR-TR40 device
family. Referencing via name/ref on the “SYLK bus”
FBox is not necessary because there is only one Sylk
bus interface per PCD7.LRxx-P5.
PCD7LR-TR40-xxx
The FBox indicates whether the PCD7.LR-TR40 is
being used for communication via the LED and the
“Offline” output.
If no data is being received by the PCD7.LR-TR40,
the LED turns red and the “Offline” output switches to
high.
As soon as the PCD7.LR-TR40 is detected and
configured (by the “SYLK bus” FBox) and values are
sent, the LED turns green and the “Offline” output
switches to low.
The PCD7.LR-TR40-xxx is available in different variants, e.g.
●
Temperature only
●
Tempe CO2
●
Tempe rel. humidity
●
TempeCO2 + rel. humidity
The FBox automatically detects which values are sent from the connected
PCD7.LR-TR40-xxx. Unavailable measured values are always displayed as
0.0 at the output.
The Sylk bus address for the PCD7.LR-TR40-xxx must be configured in the ad
-
justment parameters. The default address is 1. If only one PCD7.LR-TRxx module
is connected to the Sylk bus, the default values are correctly preset in the FBoxes.
If multiple PCD7.LR-TR40-xxx devices (max. four) are used, the Sylk bus address
in the FBox and on the associated device must be set to the same value using the
DIP switch. Permissible Sylk bus addresses are 1 to 4.
