One pc supports one USB programming cable onlyĪfter you install the STEP7 or STEP7 Micro/WIN programming software, then please install the Siemens PC_Adapter_USB driver for the USB/MPI+ V4.0 which is included in the CD.Īfter the driver is installed,it will appear “USB” option in the “Local Connection” of “Set PG/PC interface” in the STEP 7 programming software and then choose this USB port.Ĭheck whether the USB/MPI+ V4.0 work normally after the driver is installed: right click “My Computer” -> Properties->Hardware->Device Manager, and insert the USB/MPI+ V4.0 into USB port of computer, it will appear a new device in the device manager as following picture. This shows the hardware and driver work normally. Support long distance communication up to 1000m The RS485 port design with overcurrent protection and lightning The USB port design with surge protection.
High optoelectronic isolation voltage up to 1000VDC Power supply by USB port(100mA). with overcurrent Protection and Surge Protection Support STEP7 V5.2 and higher,STEP7 Micro/Win 4.0 and higher USB/MPI+ V 4.0 is the optoelectronic isolated adapter for industrial design. There is anti-surging& anti-lightning protection circuit for the USB and RS485 interface. It support hot plug. Its suitable for S7-300/400/200 series PLC. In particular, it applies to the strong interfere industrial scene and the safeguard in the circuit guarantees the safely running of the system. The working power supply of this cable USB/MPI+ V 4.0 is directly from the USB port, but not the PLC programming interface. USB/MPI+ V4.0 is the USB to MPI and PPI protocol adapter, support S7-300/400 PLC MPI or S7-200 PLC PPI communication. the same as Siemens PC Adapter USB except that this USB/MPI+ V4.0 does not support profibus communication.
