5. The Network Manager is defined as SAO Each of the FRnet must have SAO because it issues the Token stream into the network mM 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 t 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 E Device Inter communication A single device can talk to other devices by setting appropriate SA and RA node configurations m No 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 2057A User Manual Ver 1 2 Jan 2008 6 12 Specifications Table 1 1 Specifications for FR 2057TA 2057HTA modules Digital Output Output Channel Output Type Load Voltage Load Current Isolation Voltage Interface 2 wire cabling Transfer distance LED I
6. al 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 2057A User Manual Ver 1 2 Jan 2008 3 network manager SAO Based on this algorithm
