摘要
A Modbus Master system for TCP/IP communication using multi-drop type data polling between a Master station and multiple slave stations, through a single task, said system comprises: first table defining means adapted to define entries in said first table using said system, said entries being in relation to type of task being selected from Serial task or TCP/IP task; selection means to select TCP/IP task(s) from said first defined table; task creation means adapted to create and define a single task for all of said selected tasks; second table defining means adapted to define number of sockets (logical connections) adapted to be used by said system and further adapted to logically link said single task to said defined sockets; third table defining means adapted to define data points and map a plurality of slave station identities to said defined sockets; thereby allowing dynamic allocation of said sockets in correspondence with said slave stations to be polled by said master station using a single task. A method using said system is also disclosed.
