Endress+Hauser iTEMP TMT84 - System Integration

Commissioning TMT84
28 Endress+Hauser
6.4 System integration
The device is ready for system integration after commissioning using the class 2 master. To integrate
the field devices in the bus system, the PROFIBUS
®
PA system requires a description of the device
parameters such as output data, input data, data format, data volume and supported transfer rate.
These data are stored in a device master file (GSD file) that is made available to the PROFIBUS
®
PA
master during commissioning of the communication system.
Furthermore, device bitmaps can also be integrated. They appear as symbols in the network struc-
ture. The profile 3.02 device master file (GSD) allows you to exchange field devices from different
manufacturers without reconfiguration.
Generally, two different variants of the GSD are possible using the profile 3.02 (factory setting: man-
ufacturer-specific GSD):
• Manufacturer-specific GSD: This GSD ensures unrestricted functioning of the field device.
Device-specific process parameters and functions are therefore available.
• Profile GSD: varies according to the number of analog input blocks (AI). As long as a plant is
configured with the profile GSD, devices can be replaced with those from other manufacturers.
However, pay attention that the order of the cyclical process values is correct.
!
Note!
The GSD to be used to operate the plant should be decided before configuration. This setting can
be changed with a class 2 master.
The TMT84 head transmitter supports the following GSD files (see table at  Chap. 5.3.3 Current
device description files).
Each device is given an identification number (ID) from the Profibus User Organization. The name
of the GSD file is derived from this. This ID number starts with the manufacturer code 15xx for
Endress+Hauser. For better classification and clarity, Endress+Hauser GSD names are as follows:
