Siemens AG 6SE7087-6NX84-0FF5
SIMOVERT MASTERDRIVES
The SLB optional board (SIMOLINK board) is used for connecting up
drives to SIMOLINK.
Each SLB optional board is a node on SIMOLINK. The maximum
number of nodes is restricted to 201.
The SIMOLINK drive link is used for the fast transfer of data between
various drives and for the synchronization of these drives to a common
system clock. It is based on a closed ring in which all nodes are
interlinked.

Data is transferred between the individual nodes via fiber-optic cables.
Plastic or glass-fiber cables can be used as a transfer medium.
The SLB optional board has a 24 V voltage input for the external
voltage supply of the board. This ensures that data transfer in
SIMOLINK is maintained even with powered-down converter/inverter.
