S800 I/O is a comprehensive, distributed and modular process I/O system that communicates with parent controllers and PLCs over industry-standard field buses. Thanks to its broad connectivity it fits a wide range of process controllers and PLCs from ABB and others.
Features and benefits
- COMLI can be used on the build in COM3 port and optionally on the CI853 ports. The cable length can be extended considerably (to several km) using a fiber optic converter. RS-232C is the standard communication interface used for serial communication with COMLI. The CI853 supports Hot Swap. COMLI is an ABB protocol for data transmission between controllers. It is designed for asynchronous master/slave communication in half-duplex. COMLI can be used for serial communication (RS-232C) or SattBus on TCP/IP. COMLI protocol supports dial-up modem controlled from the application. AC 800M supports both master and slave functionality.
- Siemens 3964R can be used on the build in COM3 port and optionally on the CI853 ports. A standard RS-232C/485 communication channel is required.
- Self-defined Serial Communication can be used on the built in COM3 port (on an AC 800M Controller) and optionally on the CI853 ports. The CI853 also supports Hot Swap.
