L-Bus – Interface
The L-Bus interface is for coupling the local DIOLINE20 I/O modules. The L-Bus,
(Lütze-Bus) is a special fieldbus invented by company Lütze.
Switch off the power when connecting or disconnecting the I/O modules.
If not observe, the whole system can be damaged. Hot Plugging is not supported
by the system.
Connect max 10 I/O modules over the L-Bus interface.
Mind the current
consumption of the single modules. In the appendix
the according
values are listed. A total current of max 1 A is possible on the L-Bus.
