• During operation, Intelligent function
module are not installed properly or
installed on the base unit.
• In the parameter I/O allocation
settings, an Inteli (intelligent function
module) was allocated to a location
reserved for an I/O module.
• In the I/O assignment setting of the
2100
PLC parameter dialog box, the
number of points assigned to the
intelligent function module is less
than the number of points of the
mounted module.
• More than three CC-Link Safety
master modules are mounted.
• More than two CC-Link IE controller
network modules are mounted.
• More than two MELSECNET/H
2106
modules are mounted.
• More than two Ethernet modules are
mounted.
• A module that the Safety CPU
module cannot recognize has been
mounted.
The start X/Y set in the PLC
parameter's I/O assignment settings is
2107
overlapped with the one for another
module.
Corrective Action
Read the common information of the
error using the GX Developer, and
check and/or change the module that
corresponds to the numerical values
(module number) there.
Alternatively, monitor the special
registers SD 150 to SD 153 at a GX
Developer, and change the fuse at the
output module whose bit has a value of
"1".
Reset the parameter I/O allocation
setting to conform to the actual status of
the intelligent function module.
• Mount two or less CC-Link Safety
master modules.
• Mount either only one CC-Link IE
controller network module or
MESECNET/H module.
• Mount only one Ethernet module.
• Mount a module supported in the
Safety CPU module.
Make the PLC parameter's I/O
assignment setting again so it is
consistent with the actual status of the
intelligent function module.
