Code
[SP. UNIT ERROR]
A CPU module that cannot be specified in the
instruction dedicated to the multiple CPU system
was specified.
2117 ■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: Program error location
■Diagnostic Timing
• When instruction executed/STOP→RUN
[SP. UNIT ERROR]
When the online module change setting is set to
be "enabled" in the PLC parameter in a multiple
CPU system, intelligent function module controlled
by other CPU using the FROM instruction/
intelligent function module device (U \G ) is
2118
specified.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: Program error location
■Diagnostic Timing
• When instruction executed
[SP. UNIT LAY ERR.]
The locations of the Q5 B/Q6 B, QA1S6 B/
QA6 B, and QA6ADP+A5 B/A6 B are
improper.
2120 ■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
The CPU module is installed to other than the CPU
slot and slots 0 to 2.
■Collateral information
2121
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT LAY ERR.]
The QA1S6 B/QA6 B and QA6ADP+A5 B/
A6 B are used for the main base unit.
■Collateral information
2122
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
Corrective Action
Read individual information of the error using the
programming tool to identify the numeric value
(program error location). Check the error step
corresponding to the value and correct it as
necessary.
• When performing the online module change in
a multiple CPU system, correct the program so
that access will not be made to the intelligent
function module controlled by the other CPU.
• When accessing the intelligent function module
controlled by the other CPU in a multiple CPU
system, set the online module change setting to
be "disabled" by parameter.
Check the location of the base unit.
Check the loading position of the CPU module
and reinstall it at the correct slot.
Replace the main base unit with a usable one.
