10 ONLINE CHANGE IN THE MOTION SFC PROGRAM
POINT
(1) Program writing is executed during the positioning control in the online change.
Be safely careful enough for work.
(2) Programs writing to the SRAM built-in Motion CPU at the mode operated by
ROM in the online change. If the online change is executed at the mode
operated by ROM, it returns to the contents of program written in the FLASH
ROM built-in Motion CPU by the next power ON or reset of the Multiple CPU
system.
(3) If the online change is executed simultaneously to one Motion CPU from the
multiple personal computers, a program writing may not be executed. Please
do not perform.
(4) If the online changes are executed by other personal computer during the
following operation with MT Developer2, injustice of a monitor value and
operation failure may occur. Please do not perform.
• Monitor mode of the Motion SFC program
• Debug mode of the Motion SFC program
• Test mode
(5) If the online change of Motion SFC chart added newly is executed, since the
online change of Motion SFC parameter cannot be executed, it operates as the
normal task (default value).
(6) When using the SV22, the program range of [Mode allocation] of the servo
program editor screen cannot be changed by online change. If the online
change is executed by changing the virtual mode program, or command
generation axis program
are not reflected, and the online change is cancelled.
(7) If the cables between the personal computer and PLC CPU module fall out, or
the power supply of the Multiple CPU system turns OFF or resets, the program
is corrupted.
Write the program again by the data writing of MT Developer2.
(8) The online change only writes when the program being operated by the Motion
CPU and the MT Developer2 project data (before change) match. Before
writing perform a check, and when data does not match, cancel the online
change.
