TMT84 Commissioning

6.4.1 Extended formats
There are some GSD files whose modules are transferred using an extended identification (e.g.
0x42, 0x84, 0x08, 0x05). These GSD files are in the "Extended" folder.
6.4.2 Contents of download file
• All Endress+Hauser GSD files
• Endress+Hauser bitmap files
• Useful information on the devices
6.4.3 Working with the GSD files
The GSD files must be integrated in the automation system. Depending on the firmware/software
used, the GSD files can be copied into the specific program directory or read into the database using
an import function within the configuration software.
Example:
The subdirectory is …\ siemens \ step7 \ s7data \ gsd for the Siemens STEP 7 configuration soft-
ware from Siemens PLC S7-300 / 400.
Bitmap files accompany the GSD files. The measuring points are illustrated using these bitmap files.
They must be loaded in the …\ siemens \ step7 \ s7data \ nsbmp directory.
For other configuration software, ask the manufacturer of your PLC for the correct directory.
6.4.4 Compatibility with the TMT184 previous model
When replacing a device, the iTEMP
®
TMT84 head transmitter guarantees compatibility of the
cyclical data with the iTEMP
®
TMT184 previous model with profile version 3.0 (ID number 1523).
Replacement of an iTEMP
®
TMT184 with an iTEMP
®
TMT84 is possible without adjusting the
configuration of the PROFIBUS
®
DP/PA network in the automation system although the names and
identification numbers of the devices are different.
Automatic identification
Once the head transmitter is replaced, the switch from standard operating to compatibility mode
takes place automatically if the PROFIBUS Ident Number Selector parameter is set to 127 (de-
fault factory setting). Compatibility mode can also be activated by setting the PROFIBUS Ident
Number Selector parameter to 128 (Manuf. specific Ident Number 1523 - TMT184). This value
is transmitted and evaluated by the master when cyclical communication is being established. The
iTEMP
®
TMT84 is configured for either standard operating or compatibility mode on the basis of
this number.
A manual switch from operation as iTEMP
®
TMT84 or iTEMP
®
TMT184 is supported.
Notes on diagnosis in compatibility mode
• Access is direct using the block structure or device parameters for acyclical parameterization of
the iTEMP
®
TMT84 using an operating program (class 2 master).
• If parameters were changed in the device to be replaced (iTEMP
®
TMT184), (parameter setting
no longer corresponds to the original default value), these parameters must be adjusted accord-
ingly using an operating program (class 2 master) in the new iTEMP
®
TMT84.
• As the iTEMP
®
TMT84 behaves the same as an iTEMP
®
TMT184 in compatibility mode with
regard to diagnosis and status handling, only the PA profile 3.0 is supported with regard to the
diagnosis bits and status codes during operation in this mode.
