2.14 STATEBUS_IO (node number 51)
The state bus is a bus system specifically designed for Lenze controllers/PLCs.
This SB can set the state bus to LOW level and thus set all nodes connected to the state bus to a
previously selected status (e.g. TRIP, quick stop (QSP) or controller inhibit (CINH)).
The SB immediately detects when a node sets the state bus to LOW level and the corresponding
control signal can be processed in the PLC program.

·
Every device connected to the state bus can set the state bus to LOW level (multi−master
operation).
·
A maximum of 20 devices (controllers/PLCs) can be networked via the state bus.
