Profibus (Menu item 4.1)
This menu only appears in PROFIBUS devices. (7ME 5034-1xxxx).
This menu gives you the following setting options:
● 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.
Note
Each address may only be assigned for one device on the connected bus!
● 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).
Note
The connected PROFIBUS master must be configured with a device database file
(GSD) according to the set ID No.
