This document is the user manual for the Mitsubishi Micro Programmable Controller MELSEC iQ-F FX5, focusing on serial communication. In terms of safety, it emphasizes the importance of installing safety circuits and interlock circuits to ensure the safe operation of the entire system. It also mentions wiring precautions and precautions during startup and maintenance.
This user manual provides detailed instructions for the serial communication features of the Mitsubishi Electric MELSEC iQ-F FX5 series micro programmable controller. It includes essential safety warnings regarding installation, operation, and maintenance to ensure safe system performance.
The document is organized into chapters covering various communication protocols and applications. Key sections include simple PLC link functions, MC protocol functionality, variable frequency drive (VFD) communication, sequential data transfer, and support for specific communication protocols. This manual is written in Chinese.
When controlling a running PLC, you must install an interlock circuit in the sequential program to ensure the system remains safe. Additionally, read the manual and confirm safety before performing other controls like program changes or forced outputs.
Control lines and communication cables should not be bundled with or placed near main circuits, high-voltage wires, load lines, or power lines. In principle, they must be separated by more than 100mm.
Writing data to the 'System Area' or 'Non-writable Area' in the buffer storage area can cause the programmable controller system to malfunction, potentially leading to danger.
