PLC (Communication Units)（Communication Interface (Transmission Standard)：RS-422/485）

PLC Communication Units are indispensable components in the realm of factory automation, functioning as vital connectors that facilitate seamless communication between diverse components. These units serve as adept translators, enabling Programmable Logic Controllers (PLCs) to engage in coherent dialogues with an array of devices such as sensors, motors, and fellow controllers. Their versatility is underscored by compatibility with various communication protocols—RS-232, resembling a reliable telephone line for straightforward one-on-one communication; RS-422/485, operating like a sophisticated conference call accommodating multiple participants concurrently; and Ethernet, representing the high-speed expressway of industrial communication for swift and robust data exchange. In the contemporary landscape, some advanced units even incorporate photonics, harnessing the power of light signals for communication. This evolution mirrors the progressive stride of industrial communication technologies. From sensors relaying critical data to motors executing precise commands, PLC Communication Units stand as the silent conductors orchestrating a harmonious collaboration within the factory ecosystem. Their proficiency not only enhances operational efficiency but also lays the foundation for a synchronized and optimized industrial automation system.

Communication Unit For MELSEC iQ-FX5 Series

MITSUBISHI

A CC-Link V2-compatible network system can be constructed at low cost.
[Features]
・ Since it has both the functions of the master station and intelligent device station, you can use either by switching with parameters
・ When used as an intelligent device station, the transmission speed can be set to follow automatically. Since it automatically follows the transmission speed of the master station, setting mistakes are eliminated
・ It supports the access function of other stations, and with GX Works3 connected to its own station, it is possible to write, read, monitor devices, etc., of other station's sequencer in the same network
・ Since it is not necessary to connect GX Works3 to each MELSEC-iQ-F series for programming, it will reduce the work labor-hours
