8.5.3 Interbus-S address and baud rate setting
The address of the valve island outputs are determined by the physical position in the Interbus
Network.
The baud rate is fixed at 500 kBit/s.
8.5.4 Interbus-S output addressing
Output addressing of the VS18/VS26 Interbus-S valve island varies with different PLC
manufacturers and due to the increasing number of compatible Interbus-S master controllers, it
would be impractical to create detailed instructions for the Norgren node’s output addressing on
a particular master.
8.5.5 Diagnostics
The VS18/VS26 Interbus-S slave can determine the state of the +24V for the valves and report
any errors to the Interbus-S master. If the valve power is not present the master will show at the
time of configuration that a peripheral fault has occurred.
