Devices on the Network
Introduction This section describes the three CPUs which exchange data over the sample
Modbus Plus network and the strategy used to assign node addresses.
Devices The three CPUs and their functions are described in the following table:
Address
Strategy In this type of architecture, assign the lowest network address (1) to the
supervisory computer. When the network initializes, the supervisor will be the first
device to get the token, and the token rotation table will be built with respect to the
supervising device.
