Remote head module
The following table shows the system configuration of when a remote head module is mounted on a CPU slot of a main base
* 1
unit.

*1 When a remote head module is mounted on a CPU slot, a CPU module cannot be mounted.
*2 Mount modules within the range of the number of I/O points for the remote head module used. ( MELSEC iQ-R CC-Link IE Field
Network Remote Head Module User's Manual (Startup))
The number of I/O points can be checked on the engineering tool. ( GX Works3 Operating Manual)
*3 The number of mountable modules includes the empty slots. Even if the number of I/O points is set to zero for an empty slot, the slot is
counted as one module.
*4 This is the total number of the extension base units, RQ extension base units, and MELSEC-Q series extension base units.
*5 When a MELSEC-Q series module is used in the system, the overall cable distance is 13.2m.
Overall cable distance:
20m
• Shaded areas are for the power supply modules.
• "CPU" is the CPU slot, and the numbers are slot numbers.
• Modules cannot be mounted on the slots marked .
*6 Depending on a module used, mounting of the maximum number of modules may not be possible because of the rated output current of
the power supply module used. Configure the system taking the current consumption of each module into consideration.
