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

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.
