4.1
Rules of System Configuration
The system configuration must meet the following four requirements.
Number of connected extension devices
The number of extension devices that can be connected to a single system of FX5UC CPU modules is limited.
For details, refer to

Page 44 Limitations on the Number of Connected Extension Devices.
Ex.
*1 Extension power supply module and connector conversion module are not included in the number of connected extension devices.
Number of input/output points
With the FX5UC CPU modules, a total of up to 512 points or less including the number of input/output points of extension
devices (max. 256 points) and number of remote I/O points (max. 384 points) can be controlled.
For details on the number of input/output points, refer to

Page 47 Limitation on the Number of Input/Output Points.
Current consumption
The power to the extension devices is supplied from a 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 power supply capacity of the CPU
module or extension power supply module.
For details on the current consumption, refer to

Page 50 Limitation on Current Consumption.
*1 The power to the input circuit of the input module is supplied from the external power supply.
