MODULAR BUS SYSTEM

One solution for many systems

The modular bus system (MBS) of SCHLEGEL is a proprietary bus system that can be easily integrated into different communication systems. An integration into the following fieldbus systems is possible: Profibus DP, AS-Interface or CANopen, as well as Industrial Ethernet Networks like Profinet, Ethernet/IP, EtherCAT or Powerlink, and from now on IO-Link as well.

The SCHLEGEL MBS consists of the bus-specific basic module and a bus-independent extension module. The MBS is connected via the bus node of the basic module to the specific communication system. The internal communication between the basic module and the extension modules is conducted via a system-independent, proprietary data bus.

By using the extension modules up to 128 control devices like pushbuttons, selector/key switches, pilot lights etc. can be connected and controlled via one cable. The higher flexibility and reliability, as well as the minor wiring effort are the main advantages of an advanced network technology, compared to the conventional parallel wiring. The introduction of IO-Link and IIOT to the market, opened new possibilities to design and to use industrial networks even more purposely and effectively.

The modular bus system provides the flexibility to use standardised modules in a fixed grid spacing, but also the possibility to respond individually to customer-specific designs. Thanks to this dynamic system it is possible to integrate contemporary design and state-of-the-art technology in modern machine concepts and panel layouts.

Each module type has 8 inputs and 8 outputs and is designed in a 25x25mm, 27x27mm or 30x30mm mounting grid for installation into front panels. The technology of the modular bus system, however, is as flexible and adaptable as the customer's requirements. The design can also be adapted individually.

If your design plans cannot be implemented with the standardised modules, we can respond to your special design requirements anyway. For customised designs we resort to sub-modules of the modular concept by adapting only the carrier board with the command points (PCB with individual contact blocks) according to your design proposal, consequently, the cost-optimised solution also taking effect here.

TECHNICAL DESCRIPTION

Plant engineering
In the plant engineering we consider the complete plant, which usually has a main control panel and several sub-control panels. In this case, the main control panel is equipped with the basic module and according to your operating concept, with additional expansion modules. The bus node with the typical bus connection is arranged in the main control panel. It is then possible to equip more sub-control panels with expansion modules and to operate them via the main control panels using the bus data. In this application you can operate up to 128 command points with LED illumination at the maximum, and this at a cable length of 5 m between the command points and a total length of 30 m within the plant.

Mounting of standard modules
We offer the standardised modules in fixed grid spacings of 25 x 25mm / 27 x 27 mm / 30 x 30mm. The modules are attached to the pushbuttons and switches of the front panel and the contact blocks are fixed to the pushbuttons and switches by means of a locking bolt. Therefore, no additional stud bolts are needed on the front panel to mount the modules Electrically, the basic module is supplied with a supply voltage of +24V/DC and the bus signal. The extension modules are connected to each other by means of a connecting cable, thus, there is no need for an additional wiring. So the wiring effort is reduced enormously. The individual modules can be attached in the same grid spacing.
