Digital Input States.
Digital signals received from analog input modules fitted at module positions A to D (if
input 'Type' is set to 'Volt free digital input' or 'DC Digital I/P' during configuration) and
digital input module fitted at module position F. Available only if the module is fitted.
Digital Input States.
Digital signals received via Modbus serial link – see Table B.14, page 158.
Alarm States.
Available only if the relevant alarm is enabled during configuration.
Alarm Acknowledge States.
Available only if the relevant alarm is enabled during configuration. Acknowledged
alarm = 0; Unacknowledged alarm = 1. Process, Latch and Annunciator alarms only.
Alarm Groups.
Available only if any alarms are enabled during configuration. Active only if any of the
alarms assigned to a group are active.
Available only if there is at least one alarm enabled during configuration. Active only if
any of the enabled alarms are active.
Available only as a source for e-mail triggers. Causes an e-mail to be generated if any
alarm becomes active.

Totalizer Run States.
Active while totalizer is running. Available only if the relevant totalizer is enabled in the
configuration level.
Totalizer Wrap Pulse.
Available only if the totalizer option is enabled and the relevant totalizer is enabled
during configuration.
If 'Wrap Enable' set to 'On' – active for 1 second when the predetermined count has
been reached.
If 'Wrap Enable' set to 'Off' – active when the predetermined count is been reached
and remains active until the totalizer is reset
Totalizer First Stage Output (Intermediate Count).
Active for 1 second when the intermediate count has been reached. Available only if
the totalizer option is enabled and the relevant totalizer is enabled during
configuration.
Totalizer Count Pulse.
Active for 100ms each time the totalizer updates by one whole count. E.g. if two
decimal places are set, a pulse is generated when the totalizer value increments from
0.99 to 1.00 or 1.99 to 2.00
