AB 1756-CN2RXT ControlLogix-XT ControlNet Interface Module

AB 1756-CN2RXT ControlLogix-XT ControlNet Interface Module

Product Overview

Module Features: Can be configured and used like a traditional 1756 - CN2R/B module, with hardware features such as module status displays, status indicators, USB ports, BNC connectors, and more.

System Applications: ControlLogix - XT products can be used in conjunction with FLEX I/O - XT products for specific temperature range environments. Limitations on use with legacy ControlLogix components are noted, and system components are designed to meet higher environmental requirements.

Controls: Independent and redundant controls are supported. Standalone control uses one control chassis; redundant control requires two controller chassis and hardware configuration requirements such as module pairing, firmware version, network address, etc.

Pre-installation: Prepare the 1756-A5XT or 1756-A7LXT chassis, 1756-PBXT power supply, and other components. Use a small screwdriver to set the network address of the module (it needs to be unique in the standalone chassis, 00 is an invalid address), you can follow the steps to reset the module to the factory settings. The chassis and power supply need to be installed before installation. Modules can be installed in any open slot in the chassis, the number of which is limited by the rated number of power supplies.

Module Installation and Connection: Slide the module circuit board into the chassis after aligning it with the chassis rails when installing, make sure the backplane connector is properly connected and avoid forcing it in. When connecting to the network, use the specified taps, recommended direct connection taps, remove the dust cap before connecting, pay attention to the correct connection, redundancy control pairs of modules connected to the same network segment, check the status of the module after connection.

Software Setup: Installation EDS file can be uploaded from the module or downloaded from the official website. Configure RSLinx software to use USB port, need to install version 2.55 and above, pay attention to safety when connecting the USB cable, use the specified cable, after installing the USB driver, you can browse the module through the software.

Status Indication and Troubleshooting: The module status indicator and display show different information to determine the module's working status and the cause of faults, such as power failure, address error, etc. The ControlNet channel status indicator has different statuses, which can be used to determine the network faults, and according to the indication, the corresponding troubleshooting and processing.
