A Guideline on Mitsubishi Programmable Controller Systems

Mitsubishi Electric provides a wide spectrum of programmable logic controllers(PLC). Mitsubishi PLCs span from Alpha Simple Application Controller to advanced Q Series Automation Platforms. The company-made controllers are designed with various features such as multi-axis control for servo and variable frequency drives, high-speed counting, built-in and modular analog I/Os, and off-delay, on-delay, and retentive on-delay PLC timers. Mitsubishi programmable logic controllers can be used in a variety of applications like small-scale and stand-alone applications, small-to-medium-scale applications, etc. Mitsubishi Industrial Automation: Variants of Available PLCs Different types of programmable logic controllers are available in the market. Some of them are discussed below,
  1. Modular PLCs
Modular PLCs are made of a base unit that comprises processor modules and communications ports. Smaller modules can be added in modular PLCs to lengthen the functionality of the system. Modular PLCs have different types of I/O modules to increase flexibility.
  1. Fixed PLCs
Fixed PLCs are designed for specific procedure control applications. These PLC types are incapable of modification. The tasks performed by fixed PLCs are repetitive and provide cost-effective solutions.
  1. Mini PLCs
Mini PLCs are low-cost controllers capable of handling simple control applications. They have few input & output modules (I/O). Mini PLCs can be programmed with ladder logic and/or other programming languages. Key Points to Consider Before Choosing Mitsubishi PLCs You can take a few things under consideration while choosing Mitsubishi PLCs. They are as follows,
  • Input/Output Requirements
