Appendix A Setting Up the DH 485 Network DH 485 Token Rotation DH 485 Network Initialization A node holding the token can send any valid packet onto the network Each node is allowed only one transmission plus two retries each time it receives the token After a node sends one message packet it attempts to give the token to its successor by sending a token pass packet to its successor If no network activity occurs the initiator sends the token pass packet again After two retries a total of three tries the initiator will attempt to find a new Successor Important The maximum address that the initiator will search for before wrapping to zero is the value in the configurable parameter maximum node address The default value for this parameter is 31 for all initiators and responders The allowable range of the node address of an initiator is 0 to 31 The allowable address range for all responders is 1 to 31 There must be at least one initiator on the network Network initialization begins when a period of inactivity exceeding the time of a link dead timeout is detected by an initiator on the network When the time for a link dead timeout is exceeded usually the initiator with the lowest address claims the token When an initiator has the token it will begin to build the network The network requires at least one initiator to initialize it Building a network begins when the initiator that claimed the token tries to

36. you must calculate the power required by the fixed I O chassis and any input circuits and output loads that are connected through this transformer The power requirement of any fixed I O unit is 50 VA The power requirement for the input circuits is determined by the number of inputs the operating voltage and the nominal input current The power requirement for output loads is determined by the number of outputs the load voltage and load current For example if you have a 1747 L30B fixed unit with 18 AC inputs 12mA at 120 VAC and 12 triac outputs 0 5A at 120 VAC the power consumed would be 50 18 120 0 012 12 120 0 5 796 VA Important In this case 0 5 Amp is the maximum rating of the triac output at 30 C If your load draws less than 0 5 Amp this figure may be reduced accordingly The output portion of the VA calculation should reflect the current requirements of your loads In general we recommend that the transformer is oversized to provide some margin for line voltage variations and other factors Typically a transformer that is 25 larger than the calculated VA is sufficient Special Considerations Chapter 1 Selecting Your Hardware Components The recommendations given previously provide favorable operating conditions for most controller installations Your application may involve one or more of the following adverse conditions Additional measures can be taken to minimize the effect of the
