Introduction

Chemical fiber production involves multiple processes, including polymerization, pumping, filtration, spinning, and stretching, to transform crude oil into chemical fibers. A chemical fiber plant operator wanted to control and monitor a variety of motors used in production lines through variable frequency drives (VFDs). Since they used a PROFIBUS-based PLC, which is different from Modbus RTU-based VFDs, operators needed a compact and easy-to-use protocol conversion solution.

System Requirements

• Integrates different protocol communication between PLCs and VFDs quickly
• A diagnostic tool to identify problems quickly to reduce downtime

Moxa Solution

Our MGate 4101-MB-PBS protocol gateways helped the operator easily integrate numerous VFDs into a PLC, without additional programming efforts. Moxa’s protocol gateways also came with a user-friendly interface to make the device settings efficient at the initial installation. During the daily operation, our MGate 4101-MB-PBS protocol gateways built-in troubleshooting tools, such as fault alarm, protocol diagnostics, and real-time data monitoring, make it easy to find the root cause when a communication error occurs. 

Why Moxa

• Easy-to-install with a user-friendly interface
• Supports fault alarm to inform operators when power is lost
