Modbus RTU to Modbus TCP caching gateway 2 x RS-485, 2 х Ethernet, Wi-Fi

Unlike most gateways, which only re-transmit packets from one network to another, while introducing additional delay, Modbus Proxy works at its pace all along, reading the requested registers into the internal memory and responds to requests with values stored in memory. Thus, the requested registers are read from the gateway’s cache without delay over Modbus TCP, while the gateway cyclically reads them from the Modbus RTU devices and put data into cache.

Applications

1. Projects with a big number of devices and registers. Speeds up data acquisition and control for the devices or systems using slow RS-485 bus and Modbus RTU protocol.
2. Connecting extra devices to your system. Quick connection of serial devices is possible to your TCP/IP network with all the flexibility and advantages of the Ethernet.

It has the following differences:

• 1x serial, 1x Ethernet port
• Port A settings are valid only
• No coupling on RS-485
• PoE powered3
