Totalizer Block
8-96
Totalizer Block Timing Diagram, Figure 8-55, DIRECTION = DOWN, AUTO WRAP = YES
The totalizer will count down until the count value is equal to or less than the low limit. The low
limit status will be set TRUE. When the count is enough to exceed the low limit it will wrap to
the high limit value minus any carry over less than the low limit. The low limit status will remain
TRUE while the count is at the low limit. When the count wraps to the high limit the low limit
status will remain TRUE until the next time this block executes.
