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 A,
page 146 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.
Select a 'Reset source' signal (see Appendix A, page 146) – an
edge-triggered signal to reset the totalizer on a rising edge.
Set the 'Preset count' value – the value the totalizer counts from and the
value applied when the totalizer is reset.
Set the 'Predetermined count' value – the value at which the totalizer
stops or wraps.
Note.

A counter configured to count up must have a 'Preset count' value
lower than the 'Predetermined count' value. A counter configured
to count down must have a 'Preset count' value greater than the
'Predetermined count' value.

Set the required number of decimal places on the higher of the
'Preset count' value or 'Predetermined count' value.
Set the 'Intermediate count' value – the value at which a digital source is
activated. This can be used as an alarm threshold to indicate when the
'Predetermined count' value is about to be reached.
