• The location designated by the FROM/TO
instruction set is not the intelligent function mod-
ule/special function module.
• The module that does not include buffer memory
has been specified by the FROM/TO instruction.
• The intelligent function module/special function
module, Network module being accessed is
2110
faulty.
• Station not loaded was specified using the

[SP. UNIT ERROR]
• The location designated by a link direct device
(J \ ) is not a network module.
• The I/O module (intelligent function module/spe-
cial function module) was nearly removed, com-
2111
pletely removed, or mounted during running.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:Program error location
■Diagnostic Timing
• When instruction executed
[SP. UNIT ERROR]
• The module other than intelligent function mod-
ule/special function module is specified by the
intelligent function module/special function mod-
ule dedicated instruction.
Or, it is not the corresponding intelligent function
module/special function module.
• There is no network No. specified by the network
2112
dedicated instruction.
Or the relay target network does not exit.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:Program error location

bythe network dedicated instruction.
■Collateral information
2113
• Common Information:FFFF
• Individual Information:Program error location
■Diagnostic Timing
• When instruction executed/STOP
*1 CPU operation can be set in the parameters at error occurrence. (LED indication varies.)

• Read the individual information of the error using
the GX Developer, check the FROM/TO instruc-
tion that corresponds to that numerical value
(program error location), and correct when nec-
essary.
• The intelligent function module/special function
module that was accessed is experiencing a
hardware fault. Therefore, change the faulty
module. Alternatively, contact your local Mitsub-
ishi representative.
Read the individual information of the error using a
peripheral device, and check the special function
module /special function module dedicated instruc-
tion (network instruction) that corresponds to the
value (program error part) to make modification.
