In this paper, we proposed the software architecture for a data collection unit using a Modbus communication protocol. This architecture consists of three blocks - XML parsing block, database block for storing monitoring data and its meta-data and Modbus communication block. XML parsing block makes meta-data of device's memory map from xml files. After parsing the file, there are two tables for storing meta-data and monitoring data table in the database. When the data collecting unit starts to communicate with devices, Modbus communication block builds the meta-data of the device's memory map from meta-data table. With this meta-data, communication block reads the monitoring data from devices. After that, data converting module converts the data using meta-data then stores the converted data to database. So, an operator wants to add heterogeneous devices in the monitoring system, just inserts the xml files to the data collection unit. By using the proposed system, it is possible to operate and maintain a system through concentrating on the development of the quality of the product itself.
