Totalizer Configuration - ABB SM1000 User Manual

...4 CONFIGURATION

4.6.5 Totalizer Configuration

Notes.
• The Totalizer tab is displayed only if the Totalizer option is fitted.
• Current totalizer values are displayed in the Digital Indicator and Process views – see Sections 2.5 and 2.6 (Operation),
and Sections 4.5.4 and 4.5.5 (Configuration).
• For analog signal sources, the total value of a signal is calculated by counting pulses produced at a rate proportional to
the input. For digital signal 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.).

Select the totalizer action following a power failure and a
digital signal to stop and start the totalizer.
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 1 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.
