Using The Totalizer Block
Description
6
High Limit
Typically set at time of configuration. This is the value at which a totalizer counting up will stop
counting at. If the up counting totalizer is set to Wrap, then this is the value that will cause the
wrap to happen. It is also the value at which a totalizer counting down will reset to in the event of
a Reset command.
Low Limit
Typically set at time of configuration. This is the value at which a totalizer counting down will stop
counting at. If the down counting totalizer is set to Wrap, then this is the value that will cause the
wrap to happen. It is also the value at which a totalizer counting up will reset to in the event of a
Reset command.
Total Count
This is the calculated totalized output of the totalizer block. This is the floating point value
typically used for display. The minimum value is 0.0 and the maximum value is 9999999.0.
High Limit Status and Low Limit Status
These outputs provide indication if either a high or low limit within the totalizer has been reached.
When a limit has been reached its respective status output is set true. When the totalized value is
reset the status output will go false.
Predetermined Count 1 & 2 Status
These outputs provide indication if either a Predetermined Count 1 or Predetermined Count 2 has
been reached within the totalizer. When the totalized count equals or exceeds a Predetermined
Count its respective status output is set true. When the totalized value is less than the
Predetermined Count its status output will go false.
Mode
Typically set at time of configuration. Indicates the mode of the totalizer block. Normally it is set
to Run but may be set to Hold.
Figures 2 and 3 show the inside of the Totalizer block. Of particular interest is the Initial Values.
These settings are used by the Totalizer block on its first execution cycle after a configuration
has been downloaded into the instrument.
