PROBLEM TO BE SOLVED: To provide a remote monitoring controller capable of reducing amount of transmission data by reducing a size of an initialization response packet while reducing the transmission time.SOLUTION: When performing a response processing from a slave station 2 to an initialization request from the master station 1, when making an initialization request from the master station 1 to the slave station 2, the master station 1 adds a counter to an initialization request packet. The slave station 2 extracts a piece of information as a difference from a point when a previous initialization processing is made, and the counter is stored in an initialization response packet together with the difference and returns the same to the master station 1.SELECTED DRAWING: Figure 2 |
