As shown in the figure.Ģ) The transformation protocol should be selected as Modbus TCP, and the working mode is the TCP Server, and the port is 502.
Confirm that the left hook of Modbus TCP to RTU in the device support function has been selected, indicating that the device supports Modbus TCP to RTU. Use ZLVircom software to search and find the device to edit the device. Press the F1 key at any time and on-line. MODBUS Gateway software has a simple, menu-driven step by step set-up. At the same time, the program can process up to 256 connections via COM port. Modbus TCP software can then access the Modbus RTU device by accessing the IP address of 2040 (common port 502).ġ)ğirst confirm that the device is a 2040 product that supports Modbus TCP. Using MODBUS Gateway on an intermediate server or embedded computer gives you a more flexible and scalable solution with multiple settings.
#MODBUS SERVER AS APPLICATION SERVER SERIAL#
When using 2040 product the hardware connection is:Ĭonnect the serial port of 2040 with the Modbus RTU device and connect the Ethernet port to the network. NETCOM2040 and ZLSN2040 can realize the Modbus TCP to Modbus RTU, both functions are similar, but one is a finished product the other is a small embedded core modules embedded into the user circuit, embedded module can reduce the user product volume also effectively reduce the cost.
