The Allen-Bradley 1756-L71 is a ControlLogix Series A programmable automation controller. It has an available storage of 2 MB for user memory and an I/O memory of 0.98 MB. It also has an onboard 4-character alphanumeric display for you to easily monitor its run-time information and controller diagnostics. It has an open-style enclosure and 1 2.0 full-speed USB port available.
The controller supports controller redundancy as long as it is paired up with the same controller and in the same ControlNet network. The USB port communication of this controller allows configuration, programming, on-line edits, and firmware flash only. Communication options available include DeviceNet, ControlNet, EtherNet/IP, Remote I/O Data Highway Plus, Third-party process and networks, and SynchLink.
This controller can be installed in the following ControlLogix chassis: 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, and 1756-A17K. The 1756-L71 controller also ships with an optional nonvolatile memory, a 1 GB 1784-SD1 SD card in particular, but you can upgrade it to 2 GB with the 1784-SD2. It is recommended that the SD card be left installed in the controller since this is where diagnostic data will be saved, which Rockwell Automation will use for troubleshooting the issue.
It is better to use Rockwell Automation SD cards, as other SD cards have not been tested to work with the controller and using other SD cards may cause data corruption. The 1756-L71 controller also ships with three capacitor energy storage modules, two of which are removable, the 1756-ESMCAP/1756-ESMCAPK and the 1756-ESMNSE/1756-ESMNSEK with no residual WallClockTime power backup, and the nonremovable 1756-ESMNRM/1756-ESMNRMK that secures the controller by preventing USB connection and SD card use.
