Continue the tutorial: Connect and control PLC by HMI. On the previous post, you are already selecting the connection method and set the connection parameters on software (The example: connect PLC S7-200 and Delta HMI DOP-B (B07S411)). Today, we will show you how to make the communication cable by hand.
Make the PLC to HMI communication cable by hand
– It is simply, you can easy to buy the tools, equipment… at an electronic store
– Easy to make a communication cable with a low price and quickly.
– You can easy to check, replace.
– The cable is suitable for small applications, one PLC – one HMI.
– However, with medium and large applications, it is not suitable.
– Look like not pro (^_^).
– The quality of cable is dependent on by the maker experience.
Tool and equipment must have
- Welding equipment: Pencil soldering iron, Solder wire, Rosin, Soldering Iron Holder Stand, Heat shrink tube …
- Connection equipment:
– RS232 Serial Port DB9 9 Pin (Male or Female): As normal is male connector because communication port of PLC, HMI is the female connector.– Shielded Communication wire: 4 cores (or more), 0.5 – 0.75mm2. Wire length: please check the distance from PLC to HMI on control cabinet by measure tape.
