MDC-700 series
Introduction
MDC-700 provides Ethernet, RS-232 and RS-485 communication interfaces to integrate RS-232/RS-485 Modbus Slave devices into Ethernet. Through the user-defined command table, the MDC-700 will read the data of the devices connected to each COM port sequentially and merge them into a continuous address format, which is convenient for the host computer to read all the data at once.




Key Features
- Great Data Capability
- Supports up to 250 Modbus/RTU definitions (commands)
- Handles up to 9600 data points for each of of AI, AO, DI, DO types
- Efficient Communication Design
- Combines data from multiple sources into a continuous address for efficient bulk reading/writing by the host
- Each COM port communication is performed in parallel to speed up the COM port communication
- Write commands (e.g., write holding registers, write Coils) are queued with first priority to ensure fast data updates.
-
Flexible Host Connectivity
- Connects with up to 8 Modbus/TCP host controllers simultaneously
- Each COM port can have different communication parameters (eg. baudrate, data format, timeout, etc.)
- Each COM port can be used as a Modbus RTU master or slave.
- Simplifies system architecture and reduces Ethernet traffic for improved performance
- Seamless Legacy Device Upgrade
- Easily upgrades Modbus RTU devices to Ethernet-based systems
-
Ideal for SCADA applications, enabling fast deployment of centralized data monitoring solutions
-
Easy Configuration and Maintenance
- Configuration via a CSV file
- Clear structure supports efficient batch command setup
- Web-based interface for quick and easy configuration import/export and system startup
