Information About 1756-L63

The 1756-L63 is a Programmable Automation Controller (PAC) from Allen-Bradley. This controller is part of the earlier Logix controller version which is specifically part of the 5560 product series. This controller comes with an RS232 Serial communication interface as the primary communication port, however, this controller supports other communication protocols such as EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink and other 3rd party communication protols by installing Allen-Bradley communication adapters and encompass partner modules.

The 1756-L63 is a Chassis based controller. It is installed a variety of ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It is also compatible for use with standard and redundant power supplies such as 1756-PA50, 1756-PA72, 1756-PA75, 1756-PB50, 1756-PB72, 1756-PB75 or 1756-PA75R, 1756-PB75R, 1756-PSCA2, respectively. It supports implementation of controller redundancy as well as integrated motion using Serial Real-Time Communication System (SERCOS), Analog options via encoder input, LDT input, SSI input and motion over Ethernet I/P network.

This controller comes with 8 MB user memory and I/O memory of 478 KB. It may be added with non-volatile memory storage via the 1784-CF128 only which has 128 MB memory size. For I/O interfacing, this controller supports up to 128,000 Discrete Input and Output and 4000 Analog Input and Output signals. It uses battery backed-up Random Access Memory (RAM) with battery part numbers of 1756-BA1, 1756-BATM, 1756-BATA for Series A controllers and 1756-BA2 Series B controllers.

The 1756-L63 controller has a built-in RS-132 serial communication port. The communication options available for this controller include the DeviceNet, ControlNet, EtherNet/IP, SynchLink, Remote I/O, Data Highway Plus, and third-party process and device networks. Serial port communications modules that this controller supports are the Modbus via logic, DH-485, DF1 radio modem, ASCII, and the DF1 full/half-duplex modules. The continuous isolation voltage of the 1756-L63 controller is 30 Volts and it has a basic insulation type. It has also been type-tested at 720 Volts DC for 60 seconds. It has a power dissipation of 3.5 W and a thermal dissipation of 11.9 BTU/hour. Its current draw at 5.1 Volts DC is 1200 mA and its current draw at 24 Volts DC is 14 mA. It has a vibration of 2 g at 10 to 500 Hertz. The 1756-L63 controller has an operating shock of 30 g and a non-operating shock of 50 g. It also has an operating temperature range of 0 to 60 degrees Celsius and a non-operating temperature range of -40 to 85 degrees Celsius. It also has a maximum surrounding air temperature of 60 degrees Celsius.

Frequently Asked Questions about 1756-L63
Question: What is the 1756-L63?
Date Update:06/06/2025
Answer:

The 1756-L63 is a ControlLogix processor module (part of the Allen-Bradley ControlLogix family) used in large and complex automation systems.

Key specs include:

  • Memory: 8 MB
  • Communication: Multiple backplane communication channels
  • Redundancy capable for high-availability applications
  • Battery-backed RAM for data retention
Question: How do I wire the 1756-L63 processor?
Date Update:06/06/2025
Answer:
  • The processor itself plugs into a ControlLogix chassis (1756-A4, A7, A10, A13) and does not have field wiring directly.
  • Communication wiring (Ethernet, ControlNet, DeviceNet, etc.) is handled via communication modules (like 1756-ENBT for Ethernet).
  • The battery module (1756-BA2) and energy storage module (1756-ESMCAP) are connected directly to the 1756-L63.
Question: How do I program the 1756-L63?
Date Update:06/06/2025
Answer:
  • Use RSLogix 5000 or Studio 5000 Logix Designer software for programming.
  • Develop your ladder logic, function block, structured text, or SFC applications.
  • Download the program via:
    Ethernet (using 1756-ENBT or EN2T modules)
    Serial (RS-232) via the mini-DIN connector on the processor (requires the 1756-CP3 cable)
Question: How do I set up communication?
Date Update:06/06/2025
Answer:
  • Add communication modules (like 1756-ENBT for Ethernet) to the chassis.
  • In Studio 5000, configure the modules (IP address, drivers).
  • Create controller tags for I/O and communication with other devices.
Question: Can I use the 1756-L63 in a redundant system?
Date Update:06/06/2025
Answer:

Yes. The 1756-L63 supports redundancy for critical applications. Use Rockwell Automation’s redundancy configuration tools and guidelines in the redundancy user manual.
