Profibus profiles
A Profibus profile contains the data to be exchanged
between a UMG and a PLC. It is possible to read out
measurement values and statuses via eight user-defined
and four factory pre-configured Profibus profiles.
A Profibus profile can:
•
Retrieve measurement 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.
•
The 8 user-defined Profibus profiles (profile
numbers 0...7) can be edited with the GridVis
software.
•
Factory pre-configured Profibus profiles (profile
numbers 8...11) cannot be changed.
Device master file
The device master file, or GSD file, describes the Profibus
characteristics of the UMG 96RM-P. The GSD file is
required by the configuration program of the PLC.
The device master file for the UMG 96RM-P has the
filename "96RM0D44.GSD" and is included on the data
carrier as part of the scope of deliverables.
System variables
All system variables 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 floating format.
•
Big or little endian.
Big endian
= High byte before low byte.
Little endian = Low byte before high byte.
