CONTROL NETWORK SYSTEM, MASTER DEVICE, CONTROL DATA PROCESSING METHOD, AND CONTROL DATA PROCESSING PROGRAM

摘要

A control computer as a master apparatus (120) in a control network system includes a packet generation unit (133). The packet generation unit (133): selects a control command for writing a data from among packet generation information; references the packet generation information for each of the selected control command; and includes a data for write which is read from an address in a storage section (131) corresponding to the each control command, in a control packet to generate the control packet. A communication unit (135) transmits the generated control packet to a controlled object as a slave device (121).
