Our system is build using modules connected via ethernet and RS-485.
We use Modbus/TCP and Modbus/RTU 19200/8e1 as protocol with which it should is possible to use components of other vendors as well.
The RS-485 busses are connected to one or more ethernet devices and made available as Modbus/TCP service.
With your own programms you can define connections between inputs and outputs, as well as other conditions.
Usage examples: access control, time recording, light control, temperatur controlling, remote switching of servers, modell railway control, home automation, ...
we have a wide offer with boards and DIN-rail devices.
Special devices, which are not part of our standard program, can be build on request.
