2.5.4 Manufacturer specific GSD files: KR014510.GSD
The manufacturer delivers the GSD files with the entire device functionality, which is listed as
follows:
• AI: Analog Input Function Block
• FB: Function Block
There are separate settings to select the units for local display and PROFIBUS. Modifications of
the units of the display will have no effect on the data transferred via PROFIBUS.
A master class 2 tool is required to modify the units for PROFIBUS transfer.

INFORMATION!
During network configuration the user has to define which function block outputs of the signal
converter should be transferred cyclically to the master. This is performed by a bus
configuration tool (e.g. "HW- Config" for PC-S7 from Siemens). This tool offers specific functions
as follows:
1. It is possible to configure an "Empty" block (the code of an "Empty" block is defined as 0x00) on
each block number. This implies: no data are transmitted in the cyclic data telegram for this
block.
2. There is NO "Totaliser (TOT)" function block allowed on block position 1, 2, 3, 7, 8, 9, 10 and 11!
On these positions, only an "Analog Input (AI)" function block or an "Empty" block is allowed!
(Note: All codes supported by "Analog Input (AI)" - and "Totaliser (TOT)"
–
function blocks will
be found in the corresponding GSD files.)
3. There is NO "Analog Input (AI)" function block allowed on block position 4, 5 and 6! On these
positions, only a "Totaliser (TOT)" function block or an "Empty" block is allowed!
4. There is a choice of 7 different totaliser functions, which can be allocated to the blocks 4, 5
and/or 6.
