6. I/O task program processing
It described the I/O task program processing. (“E” type: P000~P003)
a. Items to be set in Task
i. Set the execution condition and priority to the task being executed. Check the
task no. to manage the task.
b. I/O task processing
i. If the interrupt signal from external signal (I/O) occurs on main unit (“E” type:
P000~P003), the task program is executed by external (I/O) signal.
c. Precaution in using I/O task program
i. If the task program which is executed by interrupt signal is on execution or
standby status, the new task program which is requested by identical I/O is
ignored.
ii. Execution request is only recognized in Run mode, thus the execution request
of task program is ignored when in Stop mode.
