4.1
Rules of System Configuration
The system configuration must meet the following four requirements.
Number of connected extension device
The number of extension devices that can be connected to a single system of FX5U CPU module is limited.
For details, refer to

Page 51 Limitations on the Number of Connected Extension Devices.
Ex.
*1 Extension power supply modules and connector conversion module are not included in the number of connected devices.
*2 When connecting the expansion board to the CPU module, only one expansion adapter can be connected.
*3 There is a limitation on the number of modules depending on the intelligent function module. For details, refer to
 Page 50
Limitations on intelligent function modules.
Number of input/output points
With the FX5UJ CPU module, a total of 256 points or less including the number of input/output points of extension devices
(max. 256 points) and number of remote I/O points can be controlled.
For details on the number of input/output points, refer to
 Page 53 Limitation on the Number of Input/Output Points.
Current consumption
Power of extension devices is supplied from the CPU module, powered input/output module or extension power supply
module.
The number of extension devices that can be connected must be determined from the capacity of the power supply.
For details on the current consumption, refer to

Page 56 Limitation on Current Consumption.
*1 Power is supplied to input circuit of input modules by 24 V DC service power supply or external power supply.
