Definition of totalizer functions
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 "Totalizer (TOT)" function block allowed on block position 1, 5, 6, 7 and 8! 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 "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 2, 3 and 4! On these
positions, only a "Totalizer (TOT)" function block or an "Empty" block is allowed!
4. There is a choice of 7 different totalizer functions, which can be allocated to the blocks 2, 3
and/or 4.
Total cyclic transfer of the totalizer value with status to the master
SetTot + Total cyclic transfer of the totalizer value with status to the master + cyclic
