S700 I/O can be used as direct I/O for AC 700F. S700 can be used as Profibus remote I/O at AC 700F, AC 800F or other Profibus Masters.
One of the S700 I/O benefits is the small footprint - the modules are featured with a high packing density, several modules are available with inputs and outputs mixed in one module. Currently, 14 different module types are available covering a wide variety of applications. Digital and analog S700 I/O modules are available. Also configurable channels are available for maximum flexibility. The I/O modules can be simply plugged onto the terminal units – for local expansion of the CPU or as Profibus Remote I/O. Currently max. eight local I/O modules can be connected to one CPU.
