PROFIBUS This menu only appears in PROFIBUS devices.
Menu item 4.1 This menu gives you the following setting options:
S
Bus address, menu item 4.1.1
The address 126 (factory setting) is reserved for newly connected
devices and must be changed to a smaller value at the latest after
commissioning on the bus. A value between 30 and 125 is
recommended because addresses below 30 are only assigned for
bus masters as a rule.
An address < 126 is only addressable when no cyclic
communication is taking place and all acyclic connections are
closed.
With the PROFIBUS variable ”factory_reset = 2712” the address
can be reset to the factory setting 126.
Every address may only be assigned for one device on the
connected bus!
S
Ident No., menu item 4.1.2
The device profile for the cyclic data traffic can be selected here.
You have the following options:
- profile-specific (=Ident No. 0x9740) means:
restricted functions; i.e. only cyclic parameters according to
profile 3.0 (flow and totalizer net).
- manufacturer-specific (= Ident No. 0x80C4) means:
full functions, i.e. cyclic parameters according to profile 3.0 and
additional
manufacturer-specific parameters (e.g. totalizer
forwards, totalizer reverse).
The connected PROFIBUS master must be configured with a device
database file (GSD) according to the set ID No.
