A high-performance and ease-of-use implementation of the Modbus protocol written in Java. Supports ASCII, RTU, TCP, and UDP transports as slave or master, automatic request partitioning and response data type parsing. - modbus4j/src/com/serotonin/modbus4
To be able to use any technology to its full capacity, it is pertinent to understand how it functions. Modbus makes use of registers in sending the different types of data. Registers are like ‘buckets’ that house data points. Some of the registers used in Modbus include the following; ...
