Overview

The SLB optional board (SIMOLINK Board) acts as the interface between SIMOREG drives and the SIMOLINK system.

The SLB is mounted on the ADB adapter board. An LBA bus adapter is needed for this purpose.

Every SLB optional board is a node in the SIMOLINK system. The maximum number of nodes is restricted to 201.

The SIMOLINK drive interface is used to exchange data rapidly between different drives and to synchronize them with a common system clock cycle. SIMOLINK is a closed circuit into which all nodes are connected.

Data are exchanged between the individual nodes by way of fiber-optic cables. Optical fibers made of glass or plastic can be used as transmission lines.

The SLB optional board has a 24 V voltage input for connecting an external voltage supply. This ensures that data can still be exchanged within the SIMOLINK circuit when the converter is switched off.

The board features three LEDs for displaying the current operational status.

Voltage supply

The optional board can be supplied with the necessary operating voltage, both internally from the SIMOREG converter and from an external source. The external power source has priority.

Switchover between the sources takes place automatically on the board.

Note

The external voltage supply must not be switched over while the bus is operating. When the supply is switched over automatically, a reset signal is generated on the board which would otherwise cause some message frames to be lost.
