UMG 509
Device master file
The device master file, abbreviated as GSD file,
describes the Profibus characteristics of the UMG 509.
The GSD file is required by the configuration program
of the PLC.
The device master file for the UMG 509 has the file name
"U5090F15.GSD" and is included on the data carrier
as part of the scope of the delivery.
Variable definition
All system variables and global variables
1)
can
be individually scaled and converted into one
of the following formats:
• 8, 16, 32 bit integer with and without sign prefix.
• 32 or 64 bit float format.
• Big or little endian.
•
Big endian = High byte before low byte.
• Little endian = Low byte before high byte.
1)
Global variables are variables that are defined by the
user in Jasic and are available to each interface in the
UMG 509.
Profibus
Profibus profiles
A Profibus profile contains the data to be exchanged
between a UMG and a PLC. Four Profibus profiles are
preconfigured at the factory.
A Profibus profile 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 hold a maximum of 127 bytes
of data. If more data has to be transferred, simply create
additional Profibus profiles.
• Every Profibus profile has a profile number.
The profile number is sent by the PLC to the UMG.
• Using GridVis, 16 Profibus profiles (profile numbers
0..15) can be edited.
• Additional Profibus profiles (profile numbers
16..255) can be created using Jasic programs.
• Factory pre-configured Profibus profiles cannot
be subsequently changed.
