For the value declared for the customs,we usually declare undervalue and send as the sample in order to save the customer's duty.If you need to declare real value,please remark it in the comments.We will do according to your idea.


PC Adapter CN:support RS232 to PROFIBUS/MPI communication

$286.00

This adapter is compatible with Siemens PC Adapter and HMI adapter,fully support  RS232 port of PC and HMI to PROFIBUS/MPI communication, use the Siemens special protocol processing chip,it can be used for Siemens S7-300/400 series PLC and other equipments with PROFIBUS/MPI interface. RS232-RS485-power supply are all optical isolated, especially suitable for the strong interference and communication interface easily damaged industrial scene.
PC Adapter CN is a high-tech adapter compatible with Siemens PC Adapter and HMI Adapter,fully support RS232 serial port of PC and HMI to PROFIBUS/MPI communication, adopt the Siemens protocol processor chip,no functional defects. PC Adapter CN is the opto-isolated adapter for industrial design.It has the surge protection and anti-lightning protection circuit on the RS232 interface and RS485 interface, support hot plug, is suitable for Siemens S7-300/400 series PLC and other equipments with PROFIBUS/MPI interface. In particular, it applies to the strong interfere industrial situations and the safeguard in the circuit guarantees the safely running of the system.
PC Adapter CN can communicate between S7-300/400PLC and RS232 interface of third party HMI,can replace the Siemens HMI Adapter.

The low version PC/MPI+ didn’t adopt the Siemens protocol processor chip,but adopt the MCU and use the software to achieve the profibus protocol,the protocol is not perfect and has the defect,only support MPI communication,not support profibus communication,can only connect few HMI and have the defect. When there are many nodes or third-party device in the network,it can’t identify every node. At the same time, it may have the risk that PC/MPI+ can’t be used after the PLC internal program is upgraded in the future.
Main Technical Specifications:
