ERROR.

When instruction 
executed

The FROM/TO instruction is executed to 
any module other than the special func-
tion module.

(1)  Review the sequence program.
(2)  Replace the faulty module with a 

new one.

QCPU

2111

The location designated by link direct 

device (J

/

) is not a network module.

2112

When instruction 
executed/

STOP

RUN

(1)  The location designated by a 

special function module dedicated 
instruction is not a special function 
module.

(2)  Alternatively, it is not the relevant 

special function module.

Review the sequence program.

2113

No special function module data for simu-
lation purposes has been set in the simu-
lation data.

Read error individual information, then 
check and edit the special function mod-
ule simulation data that corresponds to 
the numerical value there (program 
error location).

SP. UNIT 
LAY ERR.

At CPU power ON/
At reset

The location of Q

B and QA1S

B is 

improper.

Check the location of the base unit.

QCPU

2122

QA1S

B is installed to the basic base 

unit.

Install Q

B as the basic base unit.

2124

(1) A module is installed at 65th or later 

slot.

(2) A module is installed at the slot later 

than the number of slots specified 
with base allocation setting.

(3) A module is installed at the I/O 

points later than the 4,096th point.

(4) A module installed at the 4,096th 

point occupies later points.

(1)  Remove the module installed at 

65th or later slot.

(2)  Remove the module installed at 

the slot later than the number of 
slots specified with base 
allocation setting.

(3)  Remove the module installed at 

the I/O points later than the 
4,096th point.

(4)  Change the last module to a 

module which does not exceed 
the 4,096th point.

2125

(1) A module which the QCPU cannot 

recognize has been installed.

(2) There was no response form the 

intelligent function module.

(1)  Install a module which can be 

used with the QCPU.

(2)  Replace the faulty module with a 

new one.
