What to do if memory is lost on Toshiba Controller?
If memory is lost, clear the memory, download the program from the engineering tool, and restart the controller.
What to do if exception interruption is detected on Toshiba V Series?
If an exception interruption is detected, turn the power on again to restart the controller. If the error persists, replace the L3 CPU module.
What to do if code memory DL error occurs on Toshiba V Series?
If a code memory DL error occurs, format the E2PROM to clear the memory, reload the user application, and restart the controller.
What to do if user information DL error occurs on Toshiba Controller?
If a user information DL error occurs, download the program from the engineering tool and restart the controller.
What to do when an error occurs in the L3 CPU module of Toshiba V Series?
When an error occurs in the L3 CPU module, conduct an error reset operation before rebooting the CPU module.
What to do if main task is jammed on Toshiba V Series Controller?
If the main task is jammed, increase the main scan cycle or decrease the program volume for main scan tasks.
What to do if user task stop boundary is over on Toshiba Controller?
If the user task stop boundary is exceeded, clear the memory of the L3 CPU module and download the application program again.
What to do if abnormal temperature is detected in Toshiba V Series?
If an abnormal temperature is detected, first check that the air inlet of the fan unit is not blocked. Next, verify that the operating temperature is within the specified range. If necessary, lower the room temperature by turning on the air conditioner in the room where the controller is installed.
What to do if Toshiba Controller is in RUN execution with tracking cable broken?
To start the controller in RUN mode when the tracking cable is broken, carry out an error reset operation to set the operation mode to HALT. At this time, make sure that the mode switch is set to "RUN".
What to do if all intelligent I/O channels failed on Toshiba Controller?
If all intelligent I/O channels have failed, check the serial bus cable connections.
