Totaliser 1, 2 or 3
Allows you to control the three PROFIBUS counters The three menus
are identical so they are grouped together and their functions are
described in one go.

C 4.y.3
Preset Value
(predefines a “threshold” using the High Limit value and the Low Limit
value of the totaliser affected; the “THRESHOLD” bit will be set in the
long status information bytes of the PROFIBUS interface if the actual
value of the totaliser is outside these limits. This can be also used as a
status output choosing the function "preset counter X”
C 4.y.4
Reset Totaliser
(The current value of the totaliser can be set to zero)
Step 1: reset totaliser?
no:
exits the function without reset
yes:
resets the totaliser to zero and exits the function; totaliser
will restart counting at once
C 4.y.5
Error behaviour
(defines the behaviour of this function block in case of errors)
hold meas. value
totalization is continued based on the
last incoming value with good status
before the first occurrence of bad sta-
tus
ignore error:
totalization is continued using the input
values despite the bad status. The sta-
tus is ignored
stop totaliser
totalization is stopped during occur-
rence of bad status of incoming values
C 4.y.6
information
(The KROHNE Ident. No. of the circuit board, the software version
number and the production date of the circuit board will be displayed)
Note:
If you choose “y” = 1 all settings will effect FB 4 (Totaliser 1)
if you choose “y” = 2 all settings will effect FB 5 (Totaliser 2)
if you choose “y” = 3 all settings will effect FB 6 (Totaliser 3)
