Upgrading Node Controllers
This procedure provides the steps necessary to upgrade from an NC-12 node controller to
NC-S node controllers. The NC-12 supports twelve RS-422 connections while the NC-S sup-
ports eight RS-422 connections. If more that eight of the RS-422 connections on the NC-12
are being used, two NC-S node controllers are required and must be configured as described
in this procedure.
Installation Preparation
1. Backup the transport system.
A. Run the web interface and connect to the HLC.
B. Select Configuration Files on the Main Menu (see the Node Controller Inter-
face User Manual).
C. Select Download for each file in use (for example, Node Controller Configura-
tion File, MICS file, Motor Type files, and Magnet Array Type files) and save
the file.
D. Select Upgrade Software on the Main Menu.
E. Select Download for each file in use (for example, Node Controller Software
Image file and Motor ERF Image files) and save the file.
2. Shutdown the transport system.
A. Complete all material transfers (move all material to appropriate locations).
B. Command all vehicles to known safe positions.
C. Issue a reset command to all paths.
D. Once the reset has completed, turn off the main power disconnect for the trans-
port system.
3. Unplug the power cable to the old node controller.
4. Make sure all communication and signal wiring that is connected to the old node con-
troller are labeled.
5. Disconnect all communication and signal wiring that is connected to the old node con-
troller.
6. Remove the old node controller from the transport system.
NC-S Installation
There are several mounting options for the NC-S node controllers. See Mounting NC-S Node
Controllers on page 87. Use the appropriate mounting method to install the NC-S node con-
trollers. Once the node controllers are mounted, they must be connected and configured for
operation as described in Configure and Connect the New Node Controllers.
