Conditional Counter. The conditional counter is used
to generate a Maintenance alert based on a register
bit value changing a defined number of times. The
Register is the register number that will be evaluated
for changes. The first Bit setting is the bit number.
The Target is the number of times that a change will
need to take place before the Maintenance alert is
triggered. The second Bit setting defines the change
that will increase the Target count: On, Off, or
Change. “Change” is any change from a previous
state; therefore, a change from On to Off and a
change from Off to On would cause the Target count
to increase.
In the example shown, register location 25009, bit 8 will be evaluated for a state change. After the
state changes to On (second Bit setting) 5 times (Target), the maintenance alert will be triggered.
•
Totalizer. The totalizer works as an accumulator that
adds the value of a register to previously summed
values. The Totalizer will add the register value to the
accumulated value each minute. This feature be
useful for monitoring repeated changes that result in
the need for maintenance or inspection. One example
may be a furnace door opening and closing as loads
are charged and removed from the furnace.
In the example shown, the value of Register 25029
will be monitored and added to previously summed
values of the register every minute. After the
Totalizer reaches 100 (Target), a maintenance alert
“Check furnace door” will be displayed on the main
9205 screen.
The Expression option allows you to program a scaled value that will be applied to the accumulated
value. For example, if * .1 is entered as the Expression, the register value recorded each minute will
be multiplied by 0.1; the scaled value will then be added to the existing sum.
The figures below illustrate how the Totalizer works with and without an Expression applied.
