2.13 STATEBUS_IO
(Module nummer 51)
The state bus is a bus system which has been designed for Lenze controllers/PLC.
This SB can set the state bus to LOW level and control all devices connected to the state bus as set
earlier (e.g. TRIP, QSP or controller inhibit)
The SB immediately detects when a device sets the state bus to LOW level, i.e. this control signal
can be processed by the PLC program.

• Ever device connected to the state bus can set the state bus to LOW level (multi-master
operation).
• Max. 20 devices (controllers/PLCs) can be networked with the state bus.
