Corrective action
• Correct the interrupt pointer setting in the
PLC System tab of "PLC Parameter".
• Take measures not to issue an interruption
from the modules where the interrupt
pointer setting is not configured in the PLC
System tab of "PLC Parameter".
• Correct the interrupt setting of the network
parameter.
• Correct the interrupt setting of the
intelligent function module buffer memory.
• Correct the basic program of the QD51.
• Correct the interrupt pointer setting in the
PLC System tab of "PLC Parameter".
• Take measures not to issue an interruption
from the modules where the interrupt
pointer setting is not configured in the PLC
System tab of "PLC Parameter".
• Correct the Interrupt Setting of the network
parameter.
• Correct the interrupt setting of the
intelligent function module buffer memory.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the CPU
module, I/O module, intelligent function
module, END cover, branch module, or
extension module. Please consult your
local Mitsubishi representative.
