When you select the Dynamic Limit block, the following options are available.
Setting Description
Branch to Block
The block number to execute when the measurement meets the
defined criteria.
Limit Number
The limit that is used for this block, 1 or 2.
Limit Type
How the limits are compared:
 Inside: The measurement is within the limits
 Above: The measurement is above the high limit
 Below: The measurement is below the low limit
 Outside: The measurement is outside the limits
Measure Block
The block number of the block that makes the reading to be
compared; from the front panel, you can set this to Previous to use
the previous measure block.
Delta block
The branch on delta block defines a trigger model block that goes to a specified block if the difference
of two measurements meets preset criteria.
This block calculates the difference between the last two measurements from a measure block. It
subtracts the most recent measurement from the previous measurement.
The difference between the measurements is compared to the target difference. If the difference is
less than the target difference, the trigger model goes to the specified branching block. If the
difference is more than the target difference, the trigger model proceeds to the next block in the
trigger block sequence.
If you do not define the measure block, it will compare measurements of a measure block that
precedes the branch delta block. For example, if you have a measure block, a wait block, another
measure block, another wait block, and then the branch delta block, the delta block compares the
measurements from the second measure block. If a preceding measure block does not exist, an error
occurs.
When you select the Delta block, the following options are available.
Setting Description
Branch to Block
The block number of the trigger model block to execute when the
difference between the measurements is less than or equal to the
Measure Block
The block number of the measure block that makes the
measurements to be compared; if this is 0 or undefined, the trigger
model uses the previous measure block.
Target Delta
The value against which the block compares the difference
between the measurements.
