You can map the internal points of LN Series Free Programmable Controllers. Once you expose these points, you can monitor and control them from the network engine. The points include internal variables, constants, inputs, outputs, controllers, timers, and optimal start objects. Keep in mind that each mapped object contributes to the maximum object count allowed for the network engine. Table 1 shows a list of available mapping points.

Note: The target reference is the type and number of the mapped field point or network variable, which must correspond to the point or NV index in the host LonWorks enabled device. When defining the object, replace the x by the index of the object being referenced. For valid network engine object types, AI stands for analog input, AO stands for analog output, BI stands for binary input, BO stands for binary output, MI stands for multiple input, and MO stands for multiple output.
