238. witch provides targeted data transfer as it will forward a data packet to a specific port or network segment rather than all ports thus freeing up bandwidth The ability to target a packet to a specific port increases network throughput and helps to eliminate the collisions that historically make Ethernet non deterministic Switches act as intelligent repeaters to increase network distance Switches split networks into separate collision domains at each port Switches provides determinism by reducing collisions Switches increase network bandwidth throughput Switches can provide supplemental error checking With Ethernet any device can try to send a data frame at any time The arbitration protocol for carrier transmission access of the Ethernet network is called Carrier Sense Multiple Access with Collision Detect CSMA CD If two devices happen to send a data frame at the same time then a collision may occur With CSMA CD each device will first sense whether the line is idle and available for use If it is the device will begin to transmit its first frame If another device also tries to send a frame at the same time then a collision occurs and both frames are discarded Each device then waits a random amount of time and retries its transmission until it is successfully sent Unlike other Ethernet devices such as an Ethernet host adapter or Network Interface Card NIC the port of a switch does not require its own MAC address During
239. x model IMPORTANT If you map inputs to local outputs then you will not be able to write to any of those outputs direct writes are blocked If those outputs include watchdog timers this would also prevent you from clearing timeouts except by system reset So be careful in making this selection Outputs on a remote unit can still be written directly even if they are i20 targets of another unit Also if you map to internal outputs the inputs will be immediately and continuously transmitted to the outputs on the same unit without a trigger even if you provide a Span Change and or Update Time value These triggers are only used for remote writes true i20 Case Study Example i20 Operation SPAN UPDATE TIME IP ADDRESS Non Zero Address Non Zero Address Non Zero Address 0 0 0 0 Zero Address Non Zero Address Results CASE 1 The current input value is sent via i20 every 25 seconds 250x100ms CASE 2 An i20 message is sent whenever the input changes by more than 25 of the input range span i e 5V for a 10V range Additionally the module will send a heartbeat message every 60 seconds to keep the receiving socket open and ready for input This heartbeat value is the current SPAN reference value the last value sent if a new SPAN value has not occurred CASE 3 An i20 message is sent whenever the input value changes by more than 25 of the input range span Additionally an i20 message
