Network communication options

The SLC 500 family offers a variety of communication modules and devices, supporting different networks including EtherNet/IP, ControlNet, DeviceNet, DH+, DH-485, universal remote I/O, and serial networks.

NetLinx Open Network Architecture

Rockwell Automation's NetLinx open network architecture strategy utilizes open network technology to achieve seamless integration from top to bottom. NetLinx based networks - DeviceNet, ControlNet, and EtherNet/IP - all use the Common Industrial Protocol (CIP), share a common language, and a set of common communication services.

Rack and power supply

1. Rack options

The SLC modular rack offers four sizes of slots: 4, 7, 10, and 13, which can be selected according to the requirements of modular hardware components. Each rack requires its own power supply, installed on the left side of the rack. Up to 3 racks can be connected using rack interconnect cables.

Precautions for power selection:

Each rack must have a power supply

Overload may cause power shutdown or premature failure

Consider future system expansion

Calculate the total current demand using a power load worksheet

The power supply can withstand short-term power outages (20ms to 3s, depending on the load)
