First Claim
1. A control system comprising a plurality of field devices distributed in equipment and controlling input/output means, and a host controller connected to said plurality of field devices via a transmission line and controlling said field devices, said field devices and said host controller constituting a network in said equipment for control of said equipment, said control system further comprising:
- a plurality of connectors for connecting said plurality of field devices to said transmission line, said connectors having network IDs representing respective connected positions to said network; and
node address creating means for generating node addresses based on the network IDs;
wherein said connector includes a switch group corresponding with the network ID; and
said node address creating means reads on/off status of said switch group and creates the node address;
wherein said field device has a device ID representing the type of said field device; and
