user. If it is set to be “never”, the backlight will keep on. Also, the screen can be set to jump
to a screensaver screen when no key is pressed in configurable time.
Note: If the screen has jumped to a screen saver screen, the pressing of any key will not carry
out any function. Any operation will awake the screen saver to return to the original screen.
„ OP10 serial Status Control
Usually the screen changing is executed by pressing the keys. Besides, the PLC can
change screen by changing the data in register. If this property is selected, the number ‘n’ will
be written into the D300 (for example) controlling register at the beginning of running, then
OP10 will jump to screen No.n. OP10 write the current screen no. into D301, so PLC can
know the status of the status of OP10. (Users can choose the function to clear the register in
the screen. After jumping to that screen, the data in controlling register will be cleared.)
Note: The user can define the address of the interactive controlling register.
„ Encrypt the project
Users can upload the project from OP10 to Pc and edit it. If the users hope the
configuration screens in the production can’t be uploaded illegally, they can choose this
option. After choosing the option, although someone has the highest level password in the
project, he can’t upload the data.
„ Communication time
Communication time is the interval between OP10 sends two communication commands.
Its value can be set between 10ms-100ms. If the corresponding controller answers fast, the
communication time can be reduced. On the contrary, increase the time. Under the default
condition, OP10 sends communication data every 20ms.
„ Overtime
The time decides when OP10 demanding data overflows. Some controllers read data fast,
but take a long time to write data. At this condition, users can set the longest write time as
overtime to avoid data setting errors when increase data of register by degrees.
