4.6.5 Totalizer Configuration

Note. This Tab is displayed only if the Totalizer option is fitted.
Note. Current totalizer values are displayed in the Digital Indicator View and Process View – see Sections 2.5 and 2.6
(Operation), and Sections 4.5.4 and 4.5.5 (Configuration).
Information. 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 transistions are can be scaled to produce a batch total.

Set the Count direction and the Wrap action.
When the count direction is set to 'Up', the totalizer counts
up from the preset value to the predetermined value – see
'Count Range' opposite.
If Wrap Enable is set to 'On', the total is reset automatically to
the Preset value once the Predetermined value is reached.
If 'Wrap' is set to 'Off', the count stops when the pre-
determined value is reached.
Note. A wrap pulse, with a duration of 1s, occurs if the
total reaches the predetermined count and 'Wrap Enable' is
set to 'On'. If 'Wrap Enable' is set to 'Off', the wrap pulse
becomes active when the predetermined count is reached
OK
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).

Set the digital signal used to start and stop the totalizer and
determine its action on 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
Set the digital source used to stop and start the totalizer –
see APPENDIX 1.
OK
Note. This signal is edge-triggered. A rising edge
(inactive to active) starts the totalizer. A falling edge (active to
inactive) stops the totalizer.
