5-14-1 Simple Program Function
Program Pattern
Either of two program patterns can be selected. The simple program operation will not be performed
if the Program Pattern parameter is set to OFF.
(1) Pattern 1 (STOP)
Control will stop and the STOP mode will be entered when the program has ended.
(2) Pattern 2 (CONT)
Control will continue in RUN mode when the program has ended.
Starting Method
Any of the following three methods can be used to start the simple program.
• Setting the Program Start parameter to STRT.
• Turning ON an event input. (The program start must be assigned to an event input.*)
• Starting with an Operation Command using communications. (When the program start is not
assigned to an event input.)
* When the simple program is started and reset, writing is performed to non-volatile memory. Be sure to consider
the write life (1 million writes) of the non-volatile memory in the system design. When the program start is
assigned to an event input, the Program Start parameter will function as a monitor display, and the
RSET/STRT displays can be used to check when the event input has started or reset the simple program.
When this is done, the Program Start parameter functions as a monitor display only and cannot be changed
using key operations. If the Program Pattern parameter is set to OFF, the event input assignment setting will be
initialized to "None."
