2.3 CPU Numbers
CPU numbers refer to the numbers for identifying the CPU modules on the multiple CPU system or the remote head modules
on the redundant system.
* 1
*1 For details on the redundant system configuration of remote head modules, refer to the following.
MELSEC iQ-R CC-Link IE Field Network Remote Head Module User's Manual (Application)
The CPU module mounted on the CPU slot in the base unit is CPU No.1. CPU No.2, CPU No.3, and CPU No.4 are
sequentially assigned starting from the module on the right side of CPU No.1.
The multiple CPU system configuration requires the specification of mounted CPU modules, so that the I/O numbers are
assigned to the CPU modules as well. The following table lists the start I/O numbers assigned to each CPU module.
CPU number Start I/O number of CPU module
CPU No.1 3E00H
CPU No.2 3E10H
CPU No.3 3E20H
CPU No.4 3E30H
