1. channel isolated photo coupler digital output in the FRnet The T denotes the screw terminal connector allowing users to connect to the DO signals on module directly The I O data transmission is controlled by the FRnet control chip which was developed by ICPDAS It was designed to provide for a deterministic high speed network communication The communication mechanism is dominated by the token stream which is generated by the network manager located at a specific node SAO This manager provides for fixed scan time and I O synchronization capability without the need of any special communication protocol Furthermore special anti noise circuitry has also been considered and built into the FRnet control chip to ensure communication reliability This distributive digital output module must be connected to other module or a host controller with a network manger built in However the effectiveness of the FRnet connection depends on and is then ensured when the correct hardware configurations for the sender address SA and receiver address RA on the host controller and the remote module in the network have been installed properly In general the operating principle is structured by the strategy of delivering the 16 bit data from the specified sender address SAn to the corresponding receiver address RAn via_ the broadcasting method controlled by the token stream of the FR 2057 User Manual Ver 1 0 3 network manager SA2.

3. O Based on this algorithm there are some general rules that need to be followed 1 The sender address needs to be unique in order to avoid any communication collisions 2 Each of the FRnet needs at least one network manager 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 modules 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 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 a data delivery from one node 16 bit data to a multi node oss omy E See Time iat Re 3 yy oken f 3 4 5 i me A i a Start Token 1 To ke Data Data Arei Area en 4 Figure 1 1 Token stream controlled by network manager SAO FR 2057 User Manual Ver 1 0 4 An example of the FRnet application structure for delivering data from the specified sender address SAn to the corresponding receiver address RAn by a 4 wire inter module cable including a 2 wire power supply cable is shown in the figure below Host Nodes Remote Nodes Figure 1 2 The example of an FRnet application structure FR 2057 User Manual Ver 1 0 Oct 2004 5 1 1 Featur

5. es m The Token stream is used to activate data transmission from the specified SA node to the corresponding RA nodes m The Network Manager is defined as SAO Each of the FRnet must have SAO because it issues the Token stream into the network m The Token stream is produced cyclically by the hardware system SAO at the fixed time interval see Figure 1 1 Therefore the FRnet system can provide for both Isochronous and Deterministic functionalities E It can provide data transmission from one node 16 bit to one node or from one node to multiple nodes at the same time because FRnet uses the principle of delivering the data from the sender address to the receiver address Therefore the sender address must be unique but the receiver address can be different or the same in the network m The FRnet system can easily be extended by adding new modules to the network according to the FRnet principle m Device Inter communication A single device can talk to other devices by setting appropriate SA and RA node configurations mNo software overhead All data transmissions are performed automatically via the FRnet control chip Therefore there is no need for the CPU or firmware to process transmission protocols E It only needs simple RS 485 wiring m The DIN Rail mounting is provided FR 2057 User Manual Ver 1 0 Oct 2004 6 1 2 Specifications Table 1 1 Specifications for FR 2057 T 2057H T modules me EE DO module DO
