Sylk bus FBoxes
An FBox family is available for integrating the
Sylk bus wall devices type
PCD7.LR-TR40-xxx (sensor only) and
PCD7.LR-TR42-xxx (with display and keys).
PCD7LR-TR42-xxx
The application FBox view contains the “Programmable
IRM” group with a subgroup “SYLK bus”, which contains
the required FBoxes:
Changes are always made to FBoxes. For this reason, the PG5 help pages
are always the most up-to-date, provided updates are done. It is a good idea to
consult these pages when in doubt.
7.2.1
Initialising the Sylk bus interface
The Sylk bus interface must first be initialised. The “Ini
-
tialization” FBox is used for this purpose. Since there is
only one Sylk bus interface on a PCD7.LRxx-P5, config
-
uration is extremely simple, as neither the port number
nor the transfer speed needs to be set.
The “En” input initialises the interface, and the “Err” output indicates an initialisa
-
tion that has failed. This can only happen if the firmware used is obsolete (prior to
1.09.00).
Only the number of connected
PCD7.LR-TRxx devices needs
to be defined in the adjustment
parameters. This is necessary
because the FBox also configures
the PCD7.LR-TRxx devices as
soon as they are detected on the
Sylk bus.
Up to four PCD7.LR-TRxx devices can be connected, and any variant of the
PCD7.LR-TRxx can be used.
The Sylk bus supports device addresses 1–15, whereas the PCD7.LRxx-P5 al-
ways uses device address 15. Addresses 1–4 can be set in the FBoxes to suit the
PCD7.LR-TRxx.
