CompactLogix Wiring Diagram Basics
A CompactLogix wiring diagram is a visual representation of the electrical connections between a CompactLogix controller and its input and output devices. It provides a clear and concise way to understand how the controller is wired and how it will interact with the other devices in the system.
CompactLogix wiring diagrams use a variety of symbols to represent the different components and connections in the system. These symbols include:
- Controllers: Controllers are represented by rectangles with rounded corners.
- Input devices: Input devices are represented by circles.
- Output devices: Output devices are represented by triangles.
- Wires: Wires are represented by lines.
- Terminals: Terminals are represented by small squares or circles.
The following are some examples of common wiring configurations for CompactLogix controllers:
- Discrete input wiring:Discrete input wiring is used to connect discrete input devices, such as pushbuttons and switches, to a CompactLogix controller. Discrete input devices provide a binary input, meaning that they can only be in one of two states: on or off.
- Discrete output wiring:Discrete output wiring is used to connect discrete output devices, such as relays and solenoids, to a CompactLogix controller. Discrete output devices provide a binary output, meaning that they can only be in one of two states: on or off.
- Analog input wiring:Analog input wiring is used to connect analog input devices, such as thermocouples and pressure sensors, to a CompactLogix controller. Analog input devices provide a continuous input, meaning that they can provide a range of values.
- Analog output wiring:Analog output wiring is used to connect analog output devices, such as variable frequency drives and proportional valves, to a CompactLogix controller. Analog output devices provide a continuous output, meaning that they can provide a range of values.
CompactLogix wiring diagrams are an essential tool for understanding how a CompactLogix controller is wired and how it will interact with the other devices in the system. By using a wiring diagram, you can ensure that your system is wired correctly and that it will operate as intended.
Input and Output Wiring
Input and output devices are essential components of any automation system, allowing the controller to interact with the physical world. CompactLogix controllers support a wide range of input and output devices, including:
- Digital inputsare used to sense the on/off state of devices such as switches, sensors, and pushbuttons.
- Digital outputsare used to control devices such as solenoids, relays, and indicator lights.
- Analog inputsare used to measure continuous signals such as temperature, pressure, and flow rate.
- Analog outputsare used to generate continuous signals to control devices such as motors, valves, and actuators.
The wiring requirements for each type of device vary depending on the specific device and the controller model. However, some general guidelines can be followed:
- Digital inputstypically require a pull-up or pull-down resistor to ensure a defined state when the input is not connected.
- Digital outputstypically require a current-limiting resistor to protect the output transistor.
- Analog inputstypically require a signal conditioner to convert the input signal to a voltage level that the controller can understand.
- Analog outputstypically require a power amplifier to boost the output signal to a level that can drive the connected device.

Network Wiring: Compact Logix Wiring Diagram
CompactLogix controllers can be used with a variety of networks, including Ethernet, DeviceNet, and ControlNet. The wiring requirements for each type of network vary.
Ethernet Wiring, Compact logix wiring diagram
Ethernet is a high-speed network that can be used to connect a CompactLogix controller to other devices, such as HMIs, PCs, and other controllers. Ethernet cables are typically twisted pair cables, and they must be terminated with RJ-45 connectors.
DeviceNet Wiring
DeviceNet is a low-speed network that can be used to connect a CompactLogix controller to input and output devices, such as sensors and actuators. DeviceNet cables are typically shielded twisted pair cables, and they must be terminated with DeviceNet connectors.
ControlNet Wiring
ControlNet is a high-speed network that can be used to connect a CompactLogix controller to other devices, such as HMIs, PCs, and other controllers. ControlNet cables are typically shielded twisted pair cables, and they must be terminated with ControlNet connectors.
