Action to take
• Reset with the reset key.
• If the error reoccurs after resetting,
1) Change the operation cycle into
a large value in the system setting.
2) Reduce the number of command
execution of the event task or NMI
task in the system setting.
• Reset with the reset key.
• If the error reoccurs after resetting, the
relevant module or the relevant slot
(base unit) is probably faulty: replace
the module/base unit.
• Reset with the reset key.
• If the error reoccurs after resetting,
explain the error symptom and get
advice from our sales representaitive.
• Reset with the reset key.
• If the error reoccurs after resetting, the
relevant module or the relevant slot
(base unit) is probably faulty: replace
the module/base unit.
• Reset with the reset key.
• Reset with the reset key.
• Use 8 or more points of CPSTART
instruction to start programs within the
number of simultaneously startable
programs.
• Write the system setting data,
programs and parameters to the
internal FLASH ROM.
