“Total”
cyclic transfer of the totaliser value with status to the master
“ Total”
cyclic transfer of the totaliser value with status to the cyclic
control data from master to the device via the parameter SetTot
“M Total”
cyclic transfer of the totaliser value with status to the cyclic
control data from master to the device via the parameter ModeTot
“T
otal”
cyclic transfer of the totaliser value with status to the cyclic
control data from master to the device via the parameters SetTot and
ModeTot (in the given order)
“SetTot”
cyclic control data from master to the device via the parameter SetTot
“ModeTot”
cyclic control data from master to the device via the parameter ModeTot
“ ModeTot”
cyclic control data from master to the device via the parameters SetTot
and ModeTot (in the given order)
Both, the Byte SetTot and ModeTot are being sent cyclically from the Master to the device if
these bytes are inserted as output data via the PLC configurator. The meaning of these control
bytes are 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.
Important Notes:
During network configuration the user has to define which function block outputs of the
“MFC300 PROFIBUS MBP interface” should be transferred cyclically to the master. This is
done by a bus configuration tool (e.g. for PC-S7 from Siemens this will be done with the tool
“HW- Config”). This tool offers the functions described 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 means, that for this block no data is transmitted in the
cyclic data telegram.
2. There is NO “Totalizer (TOT)” function block allowed on block position 1, 2, 3, 7, 8, 9, 10 and
11! An “Analog Input (AI)” function block or an “Empty” block is allowed here only!
Note: All codes supported of “Analog Input (AI)” - and “Totalizer (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! A
“Totalizer (TOT)” function block or an “Empty” block is allowed here only!
4. There is a choice of 7 different totalizer functions, which can be allocated to the blocks 4, 5
and / or 6. The 7 functions are defined as follows:
