Wago Enhanced PLCs for serial Modbus
These Modbus-based PLCs offer complete controller functionality and serial Modbus connectivity in one compact module. The 750-815/300 and 750-816/300 series PLCs use the latest version of Wago-I/O-Pro software for programming control applications. Features include decentralized control to optimize support of higher-level PLCs or PCs, local data processing to minimize fieldbus transmissions, 32 KB of program and data memory and 8 KB of nonvolatile memory and support of Modbus RTU and ASCII over RS-485 or RS-232. PLC programming is performed in compliance with IEC 61131-3 and supports all programming languages including ladder, structured text or function block.
