Operating precautions

This section explains the precautions for using I/O modules and intelligent function modules.For details of precautions,
refer to the manual for respective modules.
The instructions dedicated to intelligent function modules cannot be used for C Controller modules.
(1) Precautions for using a CC-Link IE Controller Network module
The following restrictions are applied to the CC-Link IE controller network module controlled by the C Controller
module.
• The module cannot be used as a relay station for the data link transfer function or the routing function.
When using either of these functions, use a CC-Link IE controller network module controlled by a
programmable controller CPU as a relay station.
• The link dedicated instructions for the CC-Link IE controller network cannot be used. However, message
communication function equivalent to SEND instruction/RECV instruction is available (Page 221,
Section 13.3.1).
• Interrupt sequence program start is not applicable.
• When accessing to a redundant CPU on another station, the system of the redundant CPU cannot be
specified.
Only host system access (station-numberspecified access) is available.
• The pairing setting for the redundant system is not applicable.
(2) Precautions for using a MELSECNET/H module
The following restrictions are applied to the MELSECNET/H module controlled by the C Controller module.
• The MELSECNET/H module cannot be used on a remote I/O network.
Use of the module is allowed on a PLC-to-PLC network only.
• The module cannot be used as a relay station for the data link transfer function or the routing function.
When using either of these functions, use a MELSECNET/H module controlled by a programmable
controller CPU as a relay station.
• The link dedicated instructions for MELSECNET/H cannot be used. However, message communication
function equivalent to SEND instruction/RECV instruction is available (Page 221, Section 13.3.1).
• Interrupt sequence program start is not applicable.
• The network diagnostics (test) function is not available.
• The simple dual-structure network function is not applicable.
(The network type cannot be set to "MNET/H standby station")
• When accessing to a redundant CPU on another station, the system of the redundant CPU cannot be
specified.
Only host system access (station-numberspecified access) is available.
• The mode cannot be set to "Debug mode".
