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 to Modbus/TCP, it is an easy way to connect 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 TCP/IP protocols. The most common use of Modbus/TCP is for Ethernet attachment of PLCs and I/O modules to other simple fieldbuses or I/O networks.
The ADAM-4572 works as a network data centre and allows up to eight PCs simultaneous access. For network administration, it can also restrict configuration access to only one host PC, enhancing network security.
