ETH-MPI/DP Programming Cable Industrial Ethernet to MPI DP for S7-300/400 PLC Profinet Win7

ETH-MPI/DP Cable x1 (Ethernet cable not included
1, the hardware connection:
1) linear way that a PLC (s7-300) and a stage crew (computer), is directly connected with a crossover cable (RJ45 network cable).


2) Star way that a PLC (s7-300) and two PC (computer) or multiple PLC (S7-300) and a stage crew (computer) or multiple PLC (s7-300) and two PC (computer), in the middle need to add an Ethernet switch, connected with a straight-line (RJ45 network cable) switch and each device.
