KL6401 LON Bus Terminal
The KL6401 LON Bus Terminal enables the direct connection of LON devices for the binding of LON networks to the PLC.
It supports the transmission standard TP/FT-10 or can be used under FTT-10 and LPT-10 transceivers (TP – Twisted Pair, FT
– Free Topology). Data exchange between the most diverse systems and a LON network is simplified, since the network
variables of the connected devices are available to the Bus Coupler or the higher level bus system. The LON terminal thereby
works independently of the bus system employed and the use of several KL6401 on one Bus Coupler or on one Bus Terminal
Controller is possible. 62 SNVTs are supported per KL6401 LON Bus Terminal. All SNVT types are configurable as input or output
variables using KS2000 software. The KS2000 software generates the required XIF file that is integrated in a LON tool.
Information on the use of the KL6401:
The KL6401 can only be used in conjunction with TwinCAT software and the TwinCAT library. No Bus Couplers from the BK
series are supported if the KL6401 is used under a controller other than TwinCAT. The use of the KL6401 LON Terminal in
combination with an Embedded PC from the CX series is possible only in conjunction with TwinCAT PLC. The TwinCAT PLC
library LON is included (free of charge) in the TwinCAT installation package.

Software
The KL6401 terminal offers the possibility to configure a maximum of 62 SNVTs. These 62 SNVTs can be configured in any
combination and as inputs and/or outputs as well. The SNVTs are configured using the KS2000 configuration software, which,
apart from configuration, is also necessary for the operation of the KL6401 LON Bus Terminal. In addition, a LON tool (e.g.
Echelon ‘LonMaker’) is needed in order to carry out the ‘binding’ of the corresponding SNVTs.
