Corrective Action
Use the peripheral
device to read and
correct the error step
in the program. (Check
the setting range of the
device, BCD
conversion value and
so on.)
Use the peripheral
device to read and
correct the error step
in the program.
Reduce the special
instructions for
CC-Link executed in
each scan to within 64.
Define parameters.
(1) Take proper
countermeasures
for noise.
(2) Consult Mitsubishi
