Modbus server interfaces using TCP/IP

12 September 2001 Computer/Embedded Technology

Advantech's ADAM-4572 is an Ethernet to RS232/485/422 MODBus Server which acts as an interface between serial ModBus devices and computer hosts running ModBus/TCP on Ethernet. Fully conforming with ModBus/TCP, it is ideal for those looking for an easy way to connect their existing devices or controllers running MODBus serial protocols to an Ethernet network. It functions as a bridge between MODBus serial devices or controllers over TCP/IP Ethernet.

MODBus/TCP enables the use of MODBus messaging in an 'intranet' or 'Internet' environment using the TCP/IP protocols. The most common use of MODBus/TCP is for Ethernet attachment of PLCs and I/O modules to other simple field buses or I/O networks.

The ADAM-4572 provides automatic RS485 data flow control and offers surge protection on the RS485 line. The module is easily mounted onto a DIN rail or panel and it can be piggyback mounted.
