MELSEC iQ-F Series FX5S PLC
Offering outstanding cost performance with abundant performance features
Mitsubishi Electric Automation Inc. has expanded its MELSEC iQ-F series compact controllers to now offer a basic model providing OEMs with an all-in-one controller for small machines up to 60 I/O with integrated Ethernet connectivity. The FX5S PLC is a solution for simple automation applications at a more affordable price than the original FX5U high-performance model and FX5UJ mid-range model.
The Mitsubishi MELSEC-F Series has been reborn as the MELSEC iQ-F Series, offering enhanced high-speed bus, expanded built-in functions, advanced SSCNETIII/H support and improved engineering environment. Program and parameters are set with the GXWorks3 engineering software. From stand-alone use to networked system application, MELSEC iQ-F brings your business to the next level of industry.
Unique features of the FX5S PLC include a built-in Webserver for connection to customized webpages and CC-Link IE network capability for reliable communication to HMI, VFD, servo, and remote I/O. The MELSEC iQ-F series compact controllers have faster speeds and increased memory for programming, bringing superior performance and reliability to customers.

“The iQ-F series FX5S PLC is the perfect product for customers that need to modernize from serial to Ethernet required for modern IoT connectivity, while simultaneously keeping costs down,” said Lee Cheung product manager at Mitsubishi Electric Automation. “This basic model is programmed in the same GX Works3 software environment as other iQ-F series compact PLCs, making it a great fit for simple automation applications in packaging, material handling, food & beverage, water, and printing industries.”

Small-scale IoT with a simple model
The strength of FX5S is the CPU module has a built-in maintenance function and communication connectivity with various devices necessary for IoT of types of equipment and machines. Further expansion of IoT functions (data collection, remote monitoring, etc.) is also possible. Programless communication can be performed not only with Mitsubishi Electric PLCs, but also with other companies’ PLCs. Since device data can be obtained by just setting parameters, it is easy to build a retrofit system.
