I. RS485 interface circuit diagram inside the S7-200PLC: see the attachment for circuit diagram
In the figure, R1 and R2 are common resistance with a resistance of 10 euro. Their function is to prevent the generation of an over-current burned-out chip when the RS485 signal D + and D-short circuit are used. Z1 and Z2 are the 6 V clamping voltage, zonea diode with a maximum current of 10A. The 24 V power supply and the 5 V power supply are not isolated.
