The present invention facilitates application of an IP-based communications protocol to inter-node communication in an existing control system. A network address determining unit (105) determines a network address in an IP network (103) between a parent node (102) and a plurality of child nodes from the IP address of the parent node (102) on the basis of a received subnet mask value assigned to the parent node (102). A host address determining unit (106) determines the host address of a child node in the IP network (103) from a logical address assigned to the child node (101). An IP address configuring unit (107) combines the determined host address with the determined network address to configure an IP address of the child node (101) in the IP network (103). |
