The central coordinator is responsible for initiating communication network formation, site address allocation, site authority assignment and Management function.

The multi-line communication system has the function of dynamically switching the node role, and the external machine, the internal machine or the line controller can be switched from the site role to the central coordinator role according to actual needs. The central coordinator role setting is implemented by specifying a data frame. When the target station receives the data frame, it automatically switches the role to the central coordinator role and sends a broadcast command to control other nodes to switch to the site role.
