12.11.2 Profibus
Profibus profiles

A Profibus profile contains the data to be ex-
changed between a UMG and a PLC. Four Profib-
us profiles are preconfigured at the factory.

Using a Profibus profile you can:

·Retrieve measured values from the UMG,
·Set the digital outputs in the UMG,
·Query the status of the digital inputs in the UMG.

Each Profibus profile can contain a maximum of
127 bytes of data. If more data has to be trans-
ferred, you may create further Profibus profiles.
Each Profibus profile has a profile number. The
profile number is sent from the PLC to the UMG.

The GridVis® software allows you to directly edit
16 Profibus profiles (profile numbers 0..15).
With Jasic programs you may create additional
Profibus profiles (profile numbers 16..255).

Factory preconfigured Profibus profiles can be
changed later on.

Device master file

The device master file, abbreviated GSD file, de-
scribes the Profibus properties of the UMG. The
GSD file is required by the configuration program
of the PLC.
The device master file for your device has the file
name "U5090F15.GSD" and is available on the
Janitza homepage.

Variable definition

All system variables and global variables

1)

can be

scaled individually and converted to one of the
following formats:

·8, 16, 32-bit signed and unsigned integer.
·32 or 64-bit float format.
·Big endian

= High byte before low byte.

·Little endian = Low byte before high byte.

1)

Global variables are defined by the user in Jasic and are available to any inter-

face in the device
