13.5 Networking accessories
The modules listed in the following are for controller networking.
13.5.1 Connection elements for optical fibres
For networking with optical fibres, Lenze offer various connection elements
(optical fibre system components 212X IB), which are especially adapted to the
controllers. Connection elements are adapters with optical sender and receiver,
distributor and power supply. Optical fibres ensure very noise-resistant data
transmission.
For further information, please see the Operating Instructions LECOM-LI.
13.5.2 Level converter
With the 2101 level converter serial transmission signals of standard RS232 can
be changed to standard RS485 or RS422. Furthermore, the converter ensures
electrical isolation. It is thus possible to install the drive system with large
distances between the components (cable length < 1200m). The components
can be connected via a multi-point connection to RS485 or a point-to-point
connection to RS422.
For further information, please see the Manual 2101 (register H).
