The LEDs display additional operating statuses of the controller besides the functions in the above illustration.
These are shown in detail in the following table:
The following descriptions contain only device-specific functions. Please consult your PLC descrip-
tion for general information for the PROFIBUS and system configuration.
8.2
PROFIBUS communication
The controller can communicate over the PROFIBUS interface if 24 VDC voltage supply is present.
As long as no network voltage is present, the controller remains in an inactive status.
But interruption of the network voltage (e.g. by being switched off when a door is opened) triggers the error mes-
sage 201 (error group no. 7, network voltage/sync signal is missing) and the Alarm relay switches. This is caused
by the lack of network voltage. The error message can be deleted after the network voltage is switched on again
by activating the RS bit (
section 8.5.4 "Reset (RS)" on page 27).
The error message or switching of the Alarm relay – caused by switching off the network voltage – can be pro-
cessed or suppressed in the PLC program without difficulty.
8.3
Device master data file (GSD)
Design tools for the PROFIBUS master to be designed interpret the content of the GSD files of the slaves and
generate from them a master parameter set for the PROFIBUS master which performs the user data traffic. The
file
ROxy0613.GSD
(
xy
: GSD version; e.g. “30” for version “v3.0”) of the RES-5006 contains all information about
the controller necessary for design, e.g. the possible baud rates, parameter descriptions, alarm messages, etc.
