The Modbus to Profinet gateway (XD-MDPN100 200) enables communication between different devices through the conversion between the Modbus protocol and the Profinet protocol. Modbus is a commonly used serial communication protocol, while Profinet is an Ethernet-based industrial communication protocol. With the continuous development of industrial automation, the application of Modbus to Profinet gateway (XD-MDPN100 200) in industrial control systems will become more and more extensive.
Modbus to Profinet gateway (XD-MDPN100 200) can be used as Profinet slave, Modbus master, Modbus slave.
The Modbus to Profinet gateway (XD-MDPN100 200) is on the Profinet side, acting as a slave. Suppose the user-configured input data is L1 and the output data is L2. PN - RS232 RS485 will send data in the [0x000,L1] address range to the PROFINET network, and when data is received from the PROFINET network, PN - RS232 RS485 will write data to the [0x5dc,0x5dc+L2] address range.
The Modbus to PROFINET gateway (XD-MDPN100 200) acts as a master or slave on the Modbus side. When a serial port runs the MODBUS master protocol, all write registers and write coil commands supported by the XD-MDPN100 200 can retrieve data from the 0x000-0x5db and 0x5dc-0xbb7 address ranges and send them to the MODBUS slave. For all read register, read coil commands supported by the XD-MDPN100 200, the XD-MDPN100 200 writes the data returned from the modbus slave to the 0x000-0x5db range.
Note: The number of commands that can be configured per modbus master is 32, and each command can read a contiguous set of modbus registers.
When a serial port runs the Modbus slave protocol, the Modbus to Profinet gateway (XD-MDPN100 200) takes data from the 0x000-0x5db and 0x5dc-0xbb7 address ranges and sends it to the Modbus master without configuring any commands.
The Modbus to PROFINET solution can be used in a wide range of applications. Devices with the Modbus RTU protocol can be connected to the Profinet networkDevices with Modbus TCP IP protocol can be connected to the Ethernet networkBidirectional communication between the Modbus protocol and the PROFINET protocol can also be implemented. By using the MODBUS to PROFINET gateway (XD-MDPN100 200), the interconnection between different communication protocols can be realized, improving the overall efficiency and stability of the industrial system.
