Node Controllers
Once all Paths and Nodes have been identified on the MagneMover LITE transport system
layout, the Node Controllers and their connections to the motors at the Nodes must be defined.
This typically includes identifying the type of Node Controllers being used (the example in
Figure 3-4 shows Node Controller LITEs being used).
Node Controllers coordinate all motor operations and communicate with the High Level Con-
troller. In all MagneMover LITE transport systems one Node Controller is designated as the
High Level Controller (HLC). The HLC manages the communication between all Node Con-
trollers in the transport system and the user’s Host Controller. The Node Controller types sup-
ported by the MM LITE transport system are:
Node Controller LITE (NC LITE) – Compact Node Controller with four RS-422 ports. This
Node Controller typically supports one Node (e.g., Merge). However, some configurations of
Nodes will allow the Node Controller to support multiple Nodes (e.g., Simple and Relay).
NC-12 Node Controller – Full-size Node Controller with 12 RS-422 ports, two RS-232
ports, 16 Digital Inputs, and 16 Digital Outputs. This Node Controller can support multiple
Nodes (e.g., Merge, Diverge, and Relay) and additional functions (e.g., E-Stop, Interlocks).
Motor Communications – Identifies the communications connections between motors on the
same Path.
NOTE: All motor connections at a Node must be made to the same Node Controller.
