  • Page 7: The Wago I/O System

    The WAGO I/O System The WAGO I/O SYSTEM consists of various components which are capable of providing modular and application specific fieldbus nodes for various fieldbusses. I11.1 Setting up a fieldbus node with the WAGO I/O SYSTEM General remark: A fieldbus node consists in principle of a fieldbus coupler at the front end, a number of special function modules and a termination module which is placed at the other end.
  • Page 8 Assembly of the WAGO I/O System All components of the system can be snapped directly on a carrier rail according to EN 50022 (DIN 35). When snapping the analog or digital components onto the rail, no special sequence must be observed. The secure positioning and connection of the individual function modules and the coupler is provided by a snap-in system.
  • Page 9 The clamping force adjusts automatically to the conductor cross section. The flat clamping face of the CAGE CLAMP spring presses the conductor against the current bar without damage. Any deformation or movement of the conductor is compensated, thus eliminating the risk of a loose connection. The contact point between conductor and CAGE CLAMP is well protected against corrosive deterioration.

  • Page 19 INTERBUS S The Interbus S system (DIN 19245 part 1.2) is set up as a data ring with a central master slave access procedure. All modules are understood as one logical module. Each partner receives data at its input and sends it to the next partner at its output. There is no addressing with a data frame because each partner knows by special control signals (CLOCK, RESET, SELECT, CONTROL) where it is placed in the ring.
