Problem
Solution
Unit number set does not match setting in
the PLC I/O table configuration.
Set unit number according to the I/O table
configuration downloaded in the PLC
CPU.
Duplicate unit numbers in the PLC system Set the unit number using the rotary
switch on the front of the case so there
are no duplicated unit numbers in the
PLC system
Problem
Solution
Unit types, unit numbers, their order on the
PLC backplane or the total number of units
does not match setting in the PLC I/O table
configuration.
Set the whole PLC system configuration,
including unit types, unit numbers, total
number of units and their order in the PLC
system so the configuration matches I/O
table configuration in the PLC CPU.
Define and set your PLC configuration
and then create I/O table configuration
that match actual configuration and
download it in the PLC CPU using CX-
Programmer software.
Problem
Solution
The unit's battery level is low, or the battery
is empty (bit 1 of the
SYSTEM_ERROR
system parameter is high, see section
4-2-232 for more details on this
parameter).
Replace the battery.
Additional actions to take:
A user can always check whether the battery is low or empty using the
BATTERY_LOW
system parameter or bit 1 of the
SYSTEM_ERROR
system
parameter (for more information on
BATTERY_LOW
BASIC command see section
4-2-41). The battery status can also be checked from the PLC ladder program by
checking "Battery Low" status bit in the allocated CIO memory area (see section 3-3-1
for more details).
Problem
Solution
A fatal error (FALS) generated by the PLC
CPU, either by the system or
programmatically (from a PLC ladder
program).
Remove the cause of the problem in the
PLC, if it wasn't generated
programmatically on purpose.
