1. 1 The sender address needs to be unique in order to avoid any communication collisions 2 Each of FRnet bus needs one and only one network manger defined as SAO It plays the important role of producing the token stream in the network 3 The baud rates of the controller and the remote module need to be the same as on the FRnet 4 The communication method is controlled by delivering the data of the specified sender address SA to the corresponding receiver address RA in the sequence of token 0 to N 1 cyclically as depicted below 5 Due to the broadcasting algorithm adopted the receiver address is not required to be unique Therefore it is easy to build in data delivery from one node 16 bit data to a multi node I 8172 71 User s Manual Ver 1 1 Jan 2006 4 Fixed Time Period Start Token 1 Token 4 Data Data Area Area Figure 1 1 Token stream controlled by network manger SAO Each port of 1 8172 71 host module contains nodes from SA0 7 RA8 15 That means each port on 1 8172 71 can connect to devices which have node addresses set between RA0 7 and SA8 15 The RA node on device can receive the command data from host module Therefore remote FRnet DO modules must have RA nodes In a similar way the remote FRnet DI modules must have SA nodes The registers of SA and RA nodes on the host are mapped to a region of host s memory Users can easily control the FRnet I O module through reading an2.
