1.2 System Configuration Specifications
■ C Controller module
The following table shows the restrictions on the number of mountable modules of when a C Controller module is mounted on
a CPU slot of a main base unit.
*1 The total number of mountable CC-Link IE Controller Network-equipped modules (when the CC-Link IE Controller Network function is
used) and MELSECNET/H network modules is eight. The number of mountable CC-Link IE Controller Network-equipped modules
(when the CC-Link IE Controller Network function is used) will decrease when one or more MELSECNET/H network modules are
mounted.
*2 There are the restrictions when the CC-Link IE Controller Network function is used.
*3 The total number of mountable CC-Link IE Controller Network-equipped modules (when the CC-Link IE Controller Network function is
used) and MELSECNET/H network modules is 32. The number of mountable CC-Link IE Controller Network-equipped modules (when
the CC-Link IE Controller Network function is used) will decrease when one or more MELSECNET/H network modules are mounted.
*4 There is no restriction on the number of mountable modules when parameters are set using the dedicated instruction after "Program" in
"Module Parameter" is selected.
*5 There are the restrictions when the CC-Link IE Field Network function is used.
■ Remote head module
The following table shows the restrictions on the number of mountable modules of when a remote head module is mounted on
a CPU slot of a main base unit.
