S7-200 to TP177 Cable

[Alejin]

Hi I need to connect an S7-200 to a TP177micro operator panel peer to peer but the communication cable is not available in my supply company.



I was reading that both ports (PLC & HMI) are RS485 so I think that I can make my own cable but I don’t know the pinout. Anybody can give me this information?



Thanks
