1. The time information in the CPU Unit is used in the CPU Bus Units.
2. If the time information cannot be read from the CPU Unit, the time stamp
in the error log will be all zeros. This can occur due to CPU Unit startup
error, unit number errors, CPU error, and model number errors. If the time
is read out from a Programming Device, the time will be shown as all zeros
in the year 2000.
3. The battery must be installed in the CS-series CPU Unit, the power turned
ON, and then the time set before the clock in the CPU Unit can be used.
The time will not be set correctly in the error log unless the clock time is set
correctly.
4. An error record is not created in EEPROM when a CPU Bus Unit memory
error occurs.
The following procedures can be used to troubleshoot various problems in
system operation.
Probable cause
or the power supply voltage is too low.
The mounting screws on the FL-net Unit
are loose.
An error occurred in the FL-net Unit.
The same unit number is being used on
another Unit as well.
The FL-net Unit is not registered in an I/O
table.
The node address is set outside the range. Set the node number to between 01 and F9
An error occurred in the FL-net Unit.

Restart the CPU Unit. If the prob-
lem persists, replace the FL-net
(Ver. 2.00) Unit.

Supply power.
Make sure that the correct voltage is being
supplied.
Tighten the screws on the FL-net Unit.
Restart the PLC. If the problem persists,
replace the FL-net Unit.
Correct the unit number setting and restart
the PLC.
Use a CX-Programmer or Programming
Console to create a new I/O table.
Hex and restart the PLC.
Restart the PLC. If the problem persists,
replace the FL-net Unit.
