(4) DEVICE CONTROL PARAMETER
The method used for controlling each device is defined as described
below:
[MDI KEY]
0 : When there is no key input, a return code indicating that there is
no key input is sent to the user program. The user program needs
to check for key input.
1 : The PMC management software waits for key input.
NOTE
Key input is data input with alphanumeric keys and
command keys or just with command keys.
[GRAPHIC]
0 : The PMC management software waits until WRITE is completed.
While the software is waiting for WRITE to be completed, the task
does not enter the wait state and lower priority tasks are not
executed. A return code indicating normal termination or an error
is sent to the user program.
1 : The PMC management software waits until WRITE is completed.
While the software is waiting for WRITE to be completed, the task
enters the wait state and lower priority tasks are executed. A return
code indicating normal termination or an error is sent to the user
program.
[RS232C]
0 : The PMC management software waits until READ or WRITE is
completed. While the software is waiting for WRITE to be
completed, the task does not enter the wait state and lower priority
tasks are not executed. A return code indicating normal
termination or an error is sent to the user program.
1 : The PMC management software waits until READ or WRITE is
completed. While the software is waiting for WRITE to be
completed, the task enters the wait state and lower priority tasks
are executed. A return code indicating normal termination or an
error is sent to the user program.
[NC EDIT]
0 : The PMC management software waits until READ or WRITE is
completed. While the software is waiting for WRITE to be
completed, the task does not enter the wait state and lower priority
tasks are not executed. A return code indicating normal
termination or an error is sent to the user program.
1 : The PMC management software waits until READ or WRITE is

completed, the task enters the wait state and lower priority tasks
are executed. A return code indicating normal termination or an
error is sent to the user program.
(5) TASK LEVEL (LADDER LEVEL 3)
The priority level of Ladder Level 3 is set. Levels range from 10 to
99. Level 10 has the highest priority and level 99 has the lowest
priority. When Ladder Level 3 is not used or activated, it should be
set to 0.
When –1 is specified, only tasks with a higher priority than PMC
screen display will be executed. Only one task can be specified from
the C program and tasks (multiple specification not allowed).
