The programming cables used to interface between a PLC and a programming device can vary depending on the manufacturer and the series/model of the PLC. Here are some examples of commonly used programming cables for various PLC manufacturers:
- Siemens PLC:
- Siemens typically uses cables like the MPI (Multi Point Interface) cable for communication between a programming device and their S7 series PLCs. This cable might be referred to as an MPI cable, PPI cable, or a USB-MPI/USB-PPI converter cable.
- For Ethernet communication, Ethernet cables or Ethernet-to-USB converters might be used, depending on the specific PLC model.
- Mitsubishi PLC:
- Mitsubishi uses various cables based on the series and model of the PLC. For example, SC09 programming cables are commonly used for FX series PLCs.
- Some models might have USB programming cables or Ethernet cables for communication.
- Allen-Bradley (Rockwell Automation) PLC:
- Allen-Bradley PLCs often use programming cables like the USB-to-serial converter cable or Ethernet cables, depending on the series and model.
- The newer CompactLogix and ControlLogix series PLCs might require Ethernet/IP communication cables.
- Omron PLC:
- Omron PLCs may use USB programming cables or Ethernet cables for communication with programming devices.
- Different series and models might require specific cables.
- Schneider Electric PLC (Modicon):
- Schneider Electric PLCs might require USB programming cables or Ethernet communication cables, depending on the model and series.
- ABB PLC:
- ABB PLCs might use programming cables that are specific to their series and models. USB and Ethernet cables are commonly used for communication.
- Delta PLC:
- Delta PLCs might require USB or RS-232 programming cables, depending on the model.
- GE Fanuc PLC:
- GE Fanuc PLCs might use serial communication cables or Ethernet cables for programming and communication.
The specific programming cables used to interface between a PLC and a programming device can vary depending on the manufacturer and the series/model of the PLC. However, in general, there are several commonly used programming cables:
- RS-232 Programming Cable: This is a common type of cable that uses the RS-232 serial communication standard. It’s used to connect a programming device, such as a computer or laptop, to the PLC for programming and communication purposes.
- USB Programming Cable: USB programming cables have become more prevalent due to the widespread use of USB ports on modern computers. These cables allow direct communication between a computer and the PLC via a USB port.
- Ethernet Programming Cable: Ethernet cables are used for network communication with certain PLC models. They allow programming devices to communicate with PLCs over a local area network (LAN) using standard Ethernet protocols.
- Wireless Programming Adapter: In some cases, wireless adapters or modules can be used to establish a wireless communication link between a programming device and a PLC. This eliminates the need for physical cables and can provide more flexibility in terms of device placement.
