Controller offers Modbus RS-485 multi-drop support
Control Technology Corp. (CTC), a manufacturer of automation controllers that integrate motion control, I/O, user interfaces, and enterprise connectivity, has added Modbus RS-485 multi-drop support as a standard feature to its Model 5300 Automation Controller. The 5300 supports RS-485 in master or slave configurations; the 5300 can also fill master and slave roles concurrently for two or more connected networks (see diagram). Users can run a different protocol off of each port on the Model 5300, with TCP, RS-485, and RS-232 all supported, serving as a bridge between different protocols. "Modbus remains a time-tested and immensely popular standard," said Tom Schermerhorn, CTC President. "The Model 5300 provides maximum flexibility because it supports Modbus on multiple protocols within the same physical network."
The company says this new model is available now as part of CTC’s larger line of advanced programmable automation controllers that combine high performance control with integrated motion, flexible programming options, and quick customization for OEM applications. The Blue Fusion controller family features sophisticated state logic that ensures consistent, high-performance control using QuickBuilder software to provide an expansive set of graphical tools in a powerful programming environment.
