After the program number to be started up, is set in
the input port 023 (LSB) to 030 (MSB) with BCD,
turning ON the input port 016 starts up the program.
Turning ON the input port 016 for 0.1 sec or more.

(No.44=“2” )
Input ports 023 to 030 are set as start program
number specification ports.

(No.44=
“2” )
Caution: The maximum number of programs is 255. However, the programs able to
start up with the BCD Code indication are from No. 1 to No.99. To start up No.
100 to No. 255 when using BCD Code, start them up with using the automatic
start program startup or the program startup command “EXPG”.
2) Input the program No. 0.01sec or more after the MSEL controller is started up (after
normal start-up = RDY signal ON).
3) Set in the input ports set by I/O parameter No. 30, the program number of the program
you want to start.
4) Set the program No. and 0.05 sec. or more later, turn ON the input port 016 (program
start).
5) Turn ON input port 016 (program start) and keep it ON for 0.1 sec.
6) The specified program starts.
