Product Features
Allen Bradley 1747 L511 processor has 1K words of user memory that can be expanded to 4K words with 1747-M1(1K) or 1747-M2(4K) EEPROM memory modules for program and data.
Allen Bradley 1747-L511 has a built-in supercapacitor or an optional battery (1747-BA) built inside, and that supercapacitor or battery does memory backup to maintain data in case there was a lose in power.
Allen Bradley 1747-L511 has a built-in DH-485 port, but can only act as a slave to an SLC 5/03 or higher processor, so it cannot be an active message originator.
Allen Bradley 1747-L511 can connect to a DeviceNet network via an expansion module or use the 1747-SN for remote I/O communication. It supports comprehensive I/O diagnostics, capable of detecting system faults and field device abnormalities.
Allen Bradley 1747-L511 is equipped with LED indicator lights that display real-time operational status (RUN), CPU fault (FLT), low battery (BAT), and I/O force (FORC), among others.
Allen Bradley 1747-L511 uses RSLogix 500 software for ladder logic programming, supporting offline editing, online monitoring, and runtime modifications. It is compatible with the 1747-CP3 programming cable, connecting to a computer via an RS-232 interface.
Product Working Principle
Allen Bradley 1747-L511 employs a cyclic scanning mechanism, sequentially executing three stages, input sampling, program execution, and output refresh.
Input sampling: Reads the status of all input modules and stores them in the image table.
Program execution: Parses instructions line by line according to ladder logic, updates internal registers, and updates the output image table.
Output refresh: Writes the results of the output image table to the physical output modules.
Allen Bradley 1747-L511 also supports ladder diagram programming, where users can write logic instructions (such as relays, timers, and counters) using RSLogix 500. The program is stored in EEPROM, and the processor executes it cyclically according to the scan period.
