Troubleshooting
Symptom Correction
An error message is
displayed on the console.
Refer to the error message list.
Insertion position for a unit to
parallelize Do not place items between the Parallelize item and Parallelize Task item.
Any process units that are placed in that position will not be executed.
Insertion position of a
parallelize processing items Always insert the Parallelize Task processing item between Parallelize and Parallelize End
processing items.
Setting the Parallelize
processing item
Always use Parallelize and Parallelize End processing items in pairs.
Camera Image Input
processing items are not
being processed in parallel
Do not insert Camera Image Input processing items under Parallelize Tasks processing items.
To use a different Camera image for a measurement under a Parallelize Task processing
item, use the Camera Switching processing item under the Parallelize Task processing item.
Getting and setting the
image from more than one
Parallelize Task processing
item
Do not reference an image that is processed under a different Parallelize Task processing
item.
Getting and setting data from
more than one Parallelize
Task processing item
Do not get or set figure data from a processing unit that is inside the range of a different
Parallelize Task processing item.
Do not get or set unit data from a processing unit that is inside the range of a different
Parallelize Task processing item.
Accessing files from under
more than one Parallelize
Task processing item
Do not input or output to the same file from a processing unit that is under a different Parallelize
Task processing item.
Conditional branching under a
Parallelize Task processing
item
If you need to branch the processing items inside the range of a Parallelize Task processing
item, make sure the branch stays within the range of the Parallelize Task processing item.
Processing order of
Parallelize Tasks
The processing order for the Parallelize Task processing units is not defined.
Do not program a measurement flow that relies on a specific processing order of Parallelize
Task processing items.
Improving processing speed
with Parallelize Task
processing item
Parallel processing may not reduce transaction times as much as expected due to the
processing time of each task, and the number of CPU cores.
Before commissioning the system, always check the transaction time with the actual
measurement flow and image.
Getting and setting system
data under Parallelize Task
processing items
Do not get or set user data and system data within the range of a Parallelize Task processing
item.
