Point-to-point communication structure
Point-to-point communication can be achieved in communication channels
such as RS232, RS485, Ethernet, and wireless radio stations.
Point-to-multipoint communication structure
Point-to-multipoint communication can be realized when using RS485 and
Ethernet as communication channels. If the slave station is allowed to upload
data without being commanded by the master station to do so, the RS485
communication modes will be in conflict.
Multipoint-to-multipoint communication structure
This communication structure is supported when using the DataSite controller
on the Ethernet network.
