About 1756-L71
Allen-Bradley 1756-L71 is a ControlLogix Series A programmable automation controller. It has 2 MB of free storage space for user memory, and 0.98 MB of I / O memory. It also has an on-board 4-character alphanumeric display that allows you to easily monitor its runtime information and controller diagnostic information. It has an open case and a 2.0 full speed USB port. As long as the controller is paired with the same controller and the same ControlNet network, the controller supports controller redundancy. The controller's USB port communication allows only configuration, programming, online editing, and firmware updates. Available communication options include DeviceNet, ControlNet, EtherNet / IP, Remote I / O Data Highway Plus, third-party processes and networks, and SynchLink. It also comes with optional non-volatile memory, but you can upgrade it to 2 GB using 1784-SD2. It is recommended to keep the SD card in the controller.

The 1756-L71 controller comes with three capacitor energy storage modules, two of which are removable. At 1.2 volts DC, the current consumption is 5 mA; at 5.1 volts DC, the current consumption is 800 mA. The 1756-L71 controller also has a continuous isolation voltage of 30 V, a maximum power consumption of 2.5 W, and a heat dissipation of 8.5 BTU / hour. Its maximum analog I / O, digital I / O and total I / O are 4,000, 128,000 and 128,000, respectively. It has an operating temperature range of 0 to 60 degrees Celsius and a storage temperature range of -40 to 85 degrees Celsius. It has an upper ambient air temperature of 60 degrees Celsius and a non-condensing relative humidity of 5% to 95%. The controller has a vibration of 2G at 10 to 500 Hz and an operating shock of 30G. After installing the SD card, the non-operational shock of 50G is reduced to 45G. Other controllers may require the user to first understand PLC registers, especially bytes and bits, in order to begin addressing program elements. With the 1756-L71, the user only needs to insert a program element and select the logical channel to which the I / O is physically connected. This feature allows you to get up and running quickly with the software. In other PLCs, users may find it necessary to move a register to another register to initiate conversion and processing to obtain only analog data. The controller only requires the user to find a logical channel that physically terminates the I / O signal. The user only needs to insert a program element and select the logical channel to which I / O is physically connected. This feature allows you to get up and running quickly with the software.
