With older Delta DVP-Series PLCs, there are no USB / Enthernet ports built in, so you need a cable to connect via RS232 port.
In many cases where it is necessary to connect a PLC urgently but cannot wait to buy a cable, we can make our own programmable cable using things available in the factory. plc247.com will guide you
1. Jack port COM-DB9 Female (Connect to a computer)
2. MiniDIN-8P Male jack ( Plugs into the DELTA PLC )
Please use a torch and solder the cable according to the following diagram, paying attention to the correct pins
plc247.com tried to make a cable and connected to the PLC for a fairly stable speed, hope you will also succeed.
Thanks and best regards!
