Advanced Built-in Functions

CPU Performance	MELSEC iQ-F is powered by a high speed CPU that can execute the LD instruction in 34 ns. Furthermore, MELSEC iQ-F can execute structured programs, execute multiple programs and handle ST language and function blocks.
Built-in Ethernet Port	The Ethernet communication port can handle communication of up to 8 connections on the network, and can support multiple connections with personal computer and other device. In addition, the Ethernet communication port can handle seamless SLMP communication with the upper-level device.
Built-in RS-485 port (MODBUS^® function)	Connect to serial devices up to 50 m away with built-in RS-485 port. Control for up to 16 Mitsubishi inverters is possible with dedicated six inverter communication instructions. MODBUS is also supported and can connect up to 32 MODBUS devices such as PLCs, sensors and temperature controllers.
Built-in Analog Input/Output (with alarm output)	Example of inverter control using analog output FX5U is equipped with 12-bit 2 ch analog input and 1 ch analog output. With parameter setup, no programming is required. Value shifting, scaling and alarm output can also be set easily with parameters. Note: Only FX5U Built-in Analog Input/Output.
Built-in SD Memory Card Slot	Example of mass-production of equipment using SD memory card A built-in SD memory card slot is convenient for updating the program and mass production of equipment. Data can be logged in SD memory card, making it easy to analyze the system status and production state, etc.
Security	MELSEC iQ-F has advanced security functions ( file password, remote password, security key) to prevent data theft and illegal operations by unauthorized persons. Example of security key function
High-speed System Bus Communication	High-speed system bus communication at 1.5 K words/ms (approximately 150 times faster compared with FX3U), together with high speed CPU, allows MELSEC iQ-F to output maximum performance even when heavy data communication intelligent function modules are used.
RUN/STOP/RESET Switch	RUN/STOP/RESET switch is built in. PLC can be rebooted without turning off the main power for efficient debugging.
Battery-less and Maintenance-free	MELSEC iQ-F series holds programs and devices in nonvolatile memory such as flash ROM, and does not require a battery. *: It is possible to increase the capacity of held devices by using an optional battery.
