4.7 Profibus Operation

Caution

Caution: data transmission errors

The attempt to operate the gauge with the RS232C

interface causes data transmission errors.

This gauge must not be operated with the RS232C

interface.

For operating the gauge via Profibus, prior installation of the

device specific GSD file is required on the bus master side. This

file can be downloaded from our website.

Node Address Setting (default 01

hex

)

For unambiguous identification of the gauge in a Profibus en-

vironment, a node address is required.

LSDMSD

ADDRESS

Node address 0 … 125

dec

The node address is set in hexadecimal form

(00 … 7D

hex

) via the <MSD> and <LSD>

switches. It can not be defined via Profibus.

Example: Node address = 7D

hex

MSD

LSD

Node address >7D

hex

(>125

dec

)

The gauge starts with the node address 126

dec

. The address can

now be set via Profibus ("Set slave address", →  [5]). Addi-

tionally, via the attribute "NO_ADD_CHG" can be defined, if fur-

ther changes of the node address are permissible.
