The LocalBus, the internal power and communications bus running through the connected S-series carriers, can be extended between carriers on separate DIN rails.
Left and Right Extenders and cables are used to extend the LocalBus to S-series carriers on other DIN rails. The Right Extender connects to the right side of the last 8-Wide I/O Carrier or Power / Controller Carrier on one DIN rail and the Left Extender connects to the left side of the first 8-Wide I/O Carrier or Power / Controller Carrier on another DIN rail. The Power / Controller Carrier connected to the Right Extender can contain an S-series controller and power supply or a VIM / VIM 2 card and power supply.
Extender cables connect to the Left and Right Extenders to extend the LocalBus to the carriers on the second DIN rail. Cables are available in the following lengths:
Refer to the DeltaV S-series and CHARMs Hardware Installation manual for a step-by-step explanation of how to extend LocalBus power to other carriers.
