Works module implements two objects one node object and one drive object The node object controls the drive object Objects within a node communicate with other network objects in the same or in other nodes by exchanging network variables Therefore to control and monitor the ATV58 TRX drive controller the LonWorks master must be programmed to read and write the network variables supported by the module Network Variable Types A network variable is an object on one node that can be connected to one or more network variables on one or more additional nodes A node s network variables define its inputs and outputs from a network point of view and allow the sharing of data in a distributed application When a program writes into one of its output network variables the new value of the network variable is propagated across the network to all nodes with input network variables connected to that output network variable For example to turn on a light over a LonWorks network a switch node has its output network variable nvoSwitch connected or bound to the input variable nviSwitch on the lamp node When the switch is activated the network variable is propagated across the network and received by the lamp node which turns on the light The LonWorks to MODBUS module uses two classes of network variable types Standard Network Variable Type SNVT and Standard Configuration PropertiesType SCPT SNVT Standard Network Variable Type T
