Display Contents Explanation
98 RS-232C abnormality
RS-232C communication is slow, causing an overflow of
output data. Turn the power off then turn it on again. If the
condition does not resolve itself, the communication with
the host computer must be made faster.
97 Setting storage error
There is an error in the EEPROM memory. Press the test
switch to clear the error.
96 Buffer overflow
The N-410 send buffer has overflowed. Press the test
switch, send an "OVCLR" command from the host
computer or use the PLC to specify "Error clear".
95 Network error
This is an error in the network. Confirm that each of the ID
numbers is unique. If the ID numbers are set correctly, the
error may be due to transmission noise. Eliminate the
source of this noise.
94 PLC link error
This is displayed when communication is faulty over a PLC
link. Press the test switch to clear the error.
