Description

The 855T Control Tower Stack Light line offers DeviceNet Bases for applications where network communication is desired. All of the functionality for the DeviceNet Interface is contained within the mounting base. All light and sound modules for the 855T Control Tow er  Stack Light line are compatible with the standard bases, or with DeviceNet Bases. The entire stack is powered from the DeviceNet Network. A separate power supply is not required.

The 855T Control Tower Stack Light DeviceNet Bases allow up to five light modules, four light modules plus a combination light and sound module, four light modules plus a single-tone sound module, three light modules plus a dual-tone sound module, or three light modules plus a dual-circuit light and sound module.

Typical DeviceNet Configuration

A DeviceNet Network supports multiple Stack Light devices and allows them to communicate with other network devices (up to 64).

The DeviceNet Stack Light operates on the network as a slave device. It does not initiate communications except for a duplicate node address check on power-up. The master writes data to, and receives data back from, the DeviceNet Stack Light.

The following DeviceNet configuration shows a variety of products operating as slaves to a PLC-5 controller with a 1771-SDN DeviceNet Scanner Module.

DeviceNet Components

DeviceNet Cables and components are available from Allen-Bradley as separate cat. nos.

It is your responsibility to install and implement the DeviceNet Network and supported devices according to the DeviceNet guidelines.

Replacement Parts

The DeviceNet Stack Light Bases and pre-assembled stacks come with all the parts required to install and use the product. The installer needs only to supply the mounting hardware.

Replacement parts for 855T components (modules, replacement gaskets, and replacement lamps) are available as separate cat. nos. Refer to the Signal Solutions Selection Guide (Publication 855-SG001*-EN-P) or the Industrial Controls Catalog.

Installing the Modules

The stack light modules are installed to the base by placing a sealing o-ring between the base and the module, lining up the arrow on the bottom of the module with the line on the top of the prior module or base, and twisting the top module clockwise to lock them into place.

IMPORTANT

For more information on different modules, refer to the Signal Solutions Selection Guide (Publication 855-SG001*-EN-P) or the Industrial Controls Catalog.

The DeviceNet Base is compatible with all 24V DC 855T modules.

Connection to the Network

Wire the DeviceNet Stack Light to an operating network. If the device is an 855T-DSxxxx, the wires should be connected to a terminal block. If the device is an 855T-DMxxxx or 855T-DLxxxx, it will be connected with the quick disconnect connector. The device is fully powered by the network, therefore it is important that the device is located near a power supply.

For more information on system installation, refer to the DeviceNet Media Design Installation Guide (Publication DNET-UM072*-EN-P).
