Precautions for System Configuration

This section explains the precautions for configuring the system.
(1) Restrictions on the number of mountable modules
Modules with constraints on the number of installations are listed below.
Restricted modules
Product
CC-Link IE Controller Network
module
MELSECNET/H network
module
CC-Link IE Field Network
master/local module
CC-Link system master/local
module
Interrupt module
High-speed data logger module
GOT
*1 : Only up to 8 modules can be network parameters set and controlled by Setting/monitoring tools for C Controller module.
There is not restrictions on the number of mountable modules on the buffer memory for the network module.
For how to set the parameters by buffer memory, refer to the following.
 MELSEC-Q CC-Link IE Field Network Master/Local Module User's Manual
*2 : The module is available only when the interrupt module is selected by setting the function selector switch (SW2) to OFF.
*3 : With interrupt event settings activated, the number of installations is not restricted.
*4 : For applicable GOT models, refer to the following.
 Connection manuals for GOT2000 series (Mitsubishi Electric Products), (Non-Mitsubishi Electric Products 1),
(Non-Mitsubishi Electric Products 2), (Microcomputer, MODBUS/Fieldbus Products, Peripherals)
 Connection manuals for GOT1000 series (Mitsubishi Electric Products), (Non-Mitsubishi Electric Products 1),
(Non-Mitsubishi Electric Products 2), (Microcomputer, MODBUS Products, Peripherals)
Remark
If the No.1 module is other CPU module than the C Controller module, refer to the manual for the No.1 CPU module used for
modules with restriction on the number of installations.
(2) Time adjustment and time notification of GOT
For multiple CPU system configuration, the No.1 CPU module is the target when performing time adjustment and
time notification by GOT connected to the No.2 to No.4 C Controller modules. Synchronize the clocks of No.2-4
modules with that of the No.1.
