Code
[SP. UNIT LAY ERR.]
• Network module A1SJ71LP21, A1SJ71BR11,
A1SJ71AP21, A1SJ71AR21, or A1SJ71AT21B
dedicated for the A2USCPU has been installed.
• Network module A1SJ71QLP21 or
A1SJ71QBR11 dedicated for the Q2ASCPU has
2108
been installed.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[SP. UNIT ERROR]
• The location designated by the FROM/TO
instruction set is not the intelligent function
module/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
faulty.
• Station not loaded was specified using the
instruction whose target was the CPU share
memory.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: Program error location
2110
■Diagnostic Timing
• When instruction executed
[SP. UNIT ERROR]
• A module other than intelligent function modules
is specified with the FROM/TO instruction.
• The module specified with the FROM/TO
instruction does not have the buffer memory.
• The intelligent function module being accessed
is faulty.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: Program error location
■Diagnostic Timing
• When instruction executed
[SP. UNIT ERROR]
• The location designated by a link direct device
(J \ ) is not a network module.
• The I/O module (intelligent function module/
special function module) was nearly removed,
completely removed, or mounted during
2111
running.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: Program error location
■Diagnostic Timing
• When instruction executed
Corrective Action
Replace the network module for the A2USCPU or
the network module for the Q2ASCPU with the
MELSECNET/H module.
• Read the individual information of the error
using the programming tool to identify the
numeric value (program error location). Correct
the FROM/TO instruction corresponding to the
value as necessary.
• The cause is a hardware fault of the intelligent
function module/special function module in the
access destination. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)
• Read the individual information of the error
using the programming tool to identify the
numeric value (program error location). Correct
the FROM/TO instruction corresponding to the
value as necessary.
• Reset the CPU module and run it again. If the
same error code is displayed again, the cause
is a hardware failure of the CPU module, I/O
module, intelligent function module, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Read the individual information of the error
using the programming tool to identify the
numeric value (program error location). Correct
the FROM/TO instruction corresponding to the
value as necessary.
• The cause is a hardware fault of the intelligent
function module/special function in the access
destination. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)
