Product details
The gateway serves as a slave on one side of PROFIBUS and has MODBUS/TCP interface protocol (RJ45 interface, based on IEEE802.3, 100M, etc.) on the other side TCP/IP）。 The gateway provides a solution for transmitting PROFIBUS bus data to industrial Ethernet. Devices with MODBUS/TCP protocol interfaces (such as operation screen HMI, PLC, DCS, etc.) can be connected to the PROFIBUS bus and Siemens PLC, meeting the needs of PROFIBUS bus data access to industrial Ethernet or management IT networks.
