Details
The branch-on-user-limits block goes to a specified building block if a measurement meets the criteria set by this
command.
There are two user-defined limits: limit 1 and limit 2. Both include their own high and low values. You set these
limit threshold values as separate settings. Limit 1 and limit 2 are stored in the measurement configuration list.
You can set them to different values in different indices of the measurement configuration list to allow you to step
through different values. The results of these limit tests are recorded in the reading buffer that accompanies each
stored reading.
The type of limit can be:
•
Above: The measurement is above the value set by the limit low value. The high value is not used when
this type is selected.
•
Below: The measurement is below the value set by the limit high value. The low value is not used when
this type is selected.
•
Inside: The measurement is inside the low and high values set for the limit.
•
Outside: The measurement is outside the low and high values set for the limit.
The measurement block must be a measurement building block that occurs in the trigger model before the
branch-on-constant-limits block.
Example
trigger.model.setblock(7, trigger.BLOCK_BRANCH_LIMIT_DYNAMIC,
trigger.LIMIT_OUTSIDE, 2, 10, 5)
Configure block 7 to check if limit 2 is outside its limit values, based on the measurements made in block 5. If
values are outside the measurements, branch to block 10. If the values are not outside the measurements,
trigger model execution continues to block 8.
