ABB NTCF22 Bailey INFI Net Optical Fiber Communication Terminal Unit

Description

NTCF22 Multi tasking refers to that multiple applications can be run at the same time, and each application is called a task.
ABB robots also support multi tasking, but only if they have the multi tasking option: 623-1 Multitasking.
What’s the use of so many tasks? Usually, multi task is used for continuous communication processing between robot NTCF22 and PC, or as a simple PLC for logic operation. Through multi task, cost can be saved.

The creation steps and precautions can be learned through the following video ↓
There are three types of tasks, NORMAL, STATIC and SEMISTATIC, as shown in the following figure.
The following table describes them ↓↓↓
NORMAL responds to a “start”/”stop” request from the FlexPendant teaching pendant or other sources, and the task takes effect again.
The task will stop when an emergency stop occurs.
When STATIC restarts, the task will restart at the current location.
The task will not be stopped by an emergency stop.
The stop button on the FlexPendant teaching pendant cannot stop the task under normal circumstances. NTCF22 can be configured by the operator on the FlexPendant teaching pendant.
The SEMISTATIC system will restart the task when it is just restarted. If the related files are updated with automatically loaded modules, the modules are reloaded.
The task will not be stopped by an emergency stop.
The stop button on the FlexPendant teaching pendant cannot stop the task under normal circumstances. This can be configured by the operator on the FlexPendant teaching pendant.
To sum up, NORMAL is an ordinary task, like T_ ROB1, the task program can be modified, while STATIC and SEMISTATIC are background tasks, which automatically run with the system startup and are not affected by the control status. The task program can not be modified. If you want to modify, you need to change to the NORMAL type, and then change to the original type after modification.
The difference between STATIC and SEMISTATIC is that after the system restarts, the task will continue to run in its original location or start again. SEMISTATIC will reload the program after restarting the robot, while Static will continue to run at the last running position after restarting.
In addition, the following two points should be noted:
1、 To achieve communication between different tasks, the data type must be variable, and the data names used for communication between tasks must be consistent. There is a case about this in the video, so you can understand it, or contact the editor if you are unclear.
2、 Another thing to note is that the background program cannot have movement instructions, otherwise the system will report an error.
More practical applications still require students to explore more. This article is more about multi task cognition.
