4.6.5 Totalizer Configuration
Note.
Current totalizer values are displayed in the Digital Indicator and Process Views – see Sections 2.5 and 2.6 (Operation),
and Sections 4.5.5 and 4.5.4 (Configuration) respectively.
For analog sources, the total value of a signal is calculated by counting pulses produced at a rate proportional to the input.
For digital sources, off/on transitions are counted to produce a batch total.
Select the totalizer Count direction and Wrap action.
When the count direction is set to 'Up', the totalizer counts up
from the 'Preset count' value to the 'Predetermined count' value
– see next page.
If 'Wrap enable' is set to 'On', the total is reset automatically to
the 'Preset count' value once the 'Predetermined count' value is
reached.
If 'Wrap enable' is set to 'Off', the count stops when the
'Predetermined count' value is reached.
Note.
A wrap pulse, with a duration of 2s, occurs if the total
reaches the 'Predetermined count' value and 'Wrap enable' is
set to 'On'. If 'Wrap enable' is set to 'Off', the wrap pulse
becomes active when the 'Predetermined count' value is
reached and remains active until the totalizer is reset. The pulse
can be assigned to a relay, digital output or digital counter.
Enter the totalizer tag to be displayed in the Process view and
the Totalizer log (20 characters max).
Enter the totalizer units to be displayed in Operator views.
Select the totalizer action following a power failure:
Stop/Go recovery
Last – On power recovery, the totalizer continues in the
same state as before the failure, i.e. stopped or
running.
Stop – Totalizer stops counting.
Go
– Totalizer starts counting from the last recorded value.
Stop/Go source
Select a signal source to stop and start the totalizer. Refer to
Appendix A, page 108 for a description of the available sources.
Note.
This signal is edge-triggered. A rising edge (inactive to
active) starts the totalizer. A falling edge (active to inactive) stops
the totalizer.
