Translation ChallengesMaster/Slave vs Peer/Peer CommunicationsTHE SOLUTIONS‣ When the LonWorks interface behaves as a Modbus Masteron the Modbus side,‣ Then LonWorks inputs are treated as Modbus write variables,and LonWorks outputs are treated as Modbus read variables.‣ LonWorks outputs can be set to send when a Modbus readoccurs (using the NVUOIMX/wrbxcombination), or they can beset to send continuously at a predefined interval(NVUOIMC/wrbccombination).‣ To achieve the read/write functionality that Modbus provideswith it’s s writes, it will be necessary to provide an out put foreach input on the LonWorks side so that write values can beread back.
