The 1747 CP3 wiring diagram is a crucial aspect of industrial automation. This wiring system is used to connect the 1747-CP3 cable to the A-B SLC 500 control system. If you are in the manufacturing industry, it is vital to understand how the wiring diagram works to ensure your system runs smoothly. In this article, we will provide a comprehensive guide to the 1747 CP3 wiring diagram.
What is a 1747-CP3 cable?
The 1747-CP3 cable is a communication cable designed to connect the SLC 5/03, SLC 5/04, or SLC 5/05 controllers to programming devices such as a computer or handheld programmer. This cable communicates through the RS-232 port of the programming device and the DH-485 port of the controller.
The 1747 CP3 cable is essential for controlling devices such as motors, valves, and other industrial control systems. This cable is the primary communication link between the programming device and the control system.
Pinout of the 1747-CP3 cable
The 1747-CP3 cable has nine pins. Each pin is assigned a specific function. The following is the pinout of the 1747-CP3 cable:
| Pin Number | Signal Name |
|---|---|
| 1 | Ground |
| 2 | Transmit Data (TD) |
| 3 | Receive Data (RD) |
| 4 | Request to Send (RTS) |
| 5 | Clear to Send (CTS) |
| 6 | Data Set Ready (DSR) |
| 7 | Signal Ground (SG) |
| 8 | Data Terminal Ready (DTR) |
| 9 | Not Connected (NC) |
What is the DH-485 protocol?
The DH-485 protocol is a communication protocol designed for industrial control systems. This protocol is used to connect devices such as PLCs, drives, and other control components. The DH-485 protocol allows devices to communicate with each other over a single communication link.
The DH-485 protocol is designed to be simple and easy to use. This protocol uses a master/slave architecture, where one device acts as the master and the other devices act as slaves. The master device controls the communication link and sends requests to the slave devices.
Understanding the 1747 CP3 wiring diagram
The 1747 CP3 wiring diagram is used to connect the 1747-CP3 cable to the A-B SLC 500 control system. This wiring system is used to establish communication between the programming device and the control system. The following is an overview of the 1747 CP3 wiring diagram:
Pin connections
The 1747-CP3 cable is connected to the RS-232 port of the programming device and the DH-485 port of the control system. The following is the pin connections of the 1747-CP3 cable:
| Programming Device | Control System |
|---|---|
| Pin 1: Ground | Pin 1: Ground |
| Pin 2: Transmit Data (TD) | Pin 2: Receive Data (RD) |
| Pin 3: Receive Data (RD) | Pin 3: Transmit Data (TD) |
| Pin 4: Request to Send (RTS) | Not Connected (NC) |
| Pin 5: Clear to Send (CTS) | Not Connected (NC) |
| Pin 6: Data Set Ready (DSR) | Not Connected (NC) |
| Pin 7: Signal Ground (SG) | Pin 7: Signal Ground (SG) |
| Pin 8: Data Terminal Ready (DTR) | Pin 8: Not Connected (NC) |
| Pin 9: Not Connected (NC) | Pin 9: Not Connected (NC) |
It is essential to connect the pins correctly to ensure the communication link works correctly.
Termination resistor
The 1747 CP3 wiring diagram requires a termination resistor. This resistor is used to terminate the DH-485 communication link. The termination resistor should be placed at the end of the communication link to ensure proper communication.
