Device master file
The device master file, abbreviated with GSD
file, describes the Profibus characteristics of the
UMG511. The GSD file is required by the PLC
configuration program.
The device master file for the UMG511 has the file
name „U5110C2B.GSD“ and is contained on the
data carrier supplied with the delivery.
1)Global variables are variables that are defined by
the user in Jasic and are provided to each inter-
face in the UMG511.
Profibus
Profibus profile
A Profibus profile contains data to be exchanged
between a UMG and an SPS. Four Profibus profi-
les are pre-configured in the factory
With a Profibus profile, you can:
• call-up measurement values from the UMG,
• set the digital outputs in the UMG,
• request the status of the digital inputs in the
UMG.
Each Profibus profile can contain a maximum of
127Bytes. You can apply further Profibus profiles
if more data has to be transferred.
• Each Profibus profile has a profile number. The
profile number is sent by the PLC to the UMG.
• You can directly process 16 Profibus profiles
with GridVis (profile numbers 0..15).
• Additional Profibus profiles (profile numbers
16..255) can be applied using Jasic programs.
• Factory pre-configured Profibus profiles can
be subsequently changed.
Variable definition
All system variables and global variables1) can be
scaled individually and converted into one of the
following formats:
• 8, 16, 32Bit integer with and without sign.
• 32 or 64Bit float format.
• Big or Little Endian.
Big-Endian = High Byte before Low Byte.
Little-Endian = Low Byte before High Byte.
