The subsequent FX2 series have greatly improved the hardware and software functions. The later introduced FXo, FX0s, FX0N and FX2N series have realized miniaturization and diversification to meet the needs of different users.
Mitsubishi Fl series and FX2 series are already obsolete products. Mitsubishi Electric’s current FX series product samples only have 4 sub-series, FX1S, FXlN, FX2N and Fx2NC. Compared with the past products, there is an obvious performance-price ratio. improve. The development classification of Mitsubishi PLC at a specific time is as follows:
1. 1980-1990 Mitsubishi PLC mainly includes F\F1\F2 series of small PLCs, K/A series of medium and large PLCs
2. 1990-2000 Mitsubishi PLC is mainly divided into FX series small PLC, A series (A2S\A2US\Q2A) medium and large PLC.
3. After 2000, Mitsubishi PLC is mainly divided into FX series small PLC, Q series (Qn\QnPH) medium and large PLC
With the acceleration of the process of world economic integration, while technological development, developed countries pay more attention to the protection of the intellectual property rights of programmable controllers, and large international programmable controller manufacturers have joined the programmable controllers one after another. The International Organization for Standardization, they use many technical standards to establish technical protection barriers in line with their economic interests.
