Net-S7300 Siemens PPI/MPI/PROFIBUS to S7TCP, MODBUS TCP

Net-S7300 is used for PLCs such as Siemens S7-200/SMART S7-200/S7-300/S7-400/Siemens CNC 840D, 840DSL, etc ethernet communication; its X2 expansion interface can be connected to touchscreens (Siemens brand, PROFACE brand) and communication cables (Siemens original) that support multi-master communication.

Net-S7 300 ethernet communication Features:

Support multi-master communication, the expansion port can be connected to a touch screen or other masters.

Through the WEB server or the configuration diagnostic tool BCDevice, the device can be parameterized and run diagnostics.

The baud rate is 9.6Kbps~6Mbps adaptive.

It can be directly installed on the PPI/MPI/PROFIBUS communication port of the PLC, without an external power supply.

Support Siemens S7 Ethernet communication driver, including MicroWIN, STEP7, Portal, WinCC, etc.

Users can use high-level language programming (such as VB, VC, C#, etc.) according to the BCNetS7 protocol to realize data communication with S7-200/300/400, which is convenient for developing production management systems.

The NetS7 OPC server is provided free of charge, and the SCADA that supports the OPC channel communicates with the PLC in the OPC way.

Integrated ModbusTCP server, Modbus data area can be automatically or edited to map to S7-200/300/400 registers.

It can realize S7TCP connection and Modbus TCP communication at the same time and supports up to 32 connections of the upper computer.

Support firmware updates on the user side through Ethernet, one purchase, and permanent upgrade.

Net Function Application 

1:Programming and debugging

Net-S-300 ethernet module supports programming and debugging of PLC control system (MicroWIN, STEP7, Botu software).

2:SCADA Ethernet communication

Net-S-300 ethernet module supports Ethernet communication with almost all SCADA monitoring and configuration software on the market, such as WINCC, MCGS, INTOUCH, IFIX, LABVIEW, etc.

3: OPC communication

Net-S-300 ethernet module supports Ethernet communication with mainstream OPC servers in the market, such as KEPWARE OPC, PC ACCESS OPC, etc. In addition, based on the BCNetS7 protocol, we have developed a completely free BCNetS7 OPC server, which can connect up to 1023 devices and is suitable for data collection of large-scale equipment networking projects.

4: Touch screen Ethernet communication

Net-S-300 ethernet module supports Ethernet communication with the mainstream touch panels in the market, such as Siemens KTP/TP series, Siemens SmartIE series, and S7300, etc.

5:ModbusTCP communication

Net-S-300 ethernet module integrates ModbusTCP server function, the host software (ModusTCP client) can directly access the internal register address data of the PLC control system according to the address mapping table, the address mapping table can use the default or freely define the mapping relationship, which makes the communication more flexible.

6: High-level language programming

BCNet-S-300 ethernet module provides an open Ethernet protocol (BCNetS7 protocol) for engineers to develop communication program software.

7: PLC Data Exchange

Net-S7 module (only BCNet Plus supports this function, BCNet (basic version) does not) supports Siemens S7-1200, S7-1500, and SMART 200PLC ethernet communication.

8:Modbus communication

Net-S-300 ethernet module (only Net-S7300 Plus bridge type supports this function) supports the Modbus function, which can be used as Modbus master or Modbus slave to realize communication between PLC and other Modbus devices.
