Running Hour Counter This function calculates the total active time of the selected digital
input, virtual I/O or output matrix output signal. The resolution is
ten seconds.

Timers The Allen-Bradley protection platform includes four settable timers
that can be used together with the user's programmable logic or to
control setting groups and other applications that require actions
based on calendar time. Each timer has its own settings. The selected
on-time and off-time is set and then the activation of the timer can be
set to be as daily or according the day of week (See the setting
parameters for details). The timer outputs are available for logic
functions and for the block and output matrix.
