diagnostics counter in r748.002 counts the CRC errors, and the counter
in r748.003 the timeout errors. From firmware version V1.50 onwards,
these counters can also be connected to the trace memory via
connectors K7082 (CRC) and K7083 (timeout). The diagnostics
counters are reset every time the power is switched (OFF) ON. After
the power has been switched ON and initialization completed, the CRC
error count should stand at zero and the timeout error count at 1, 2 or 3.
The SLB optional board is provided with connection X470 for the
external voltage supply of the optional board. The external voltage
supply is available in addition to the internal voltage supply through the
converter/inverter.
If you wish the converter/inverter in which the SLB optional board is
installed to be disconnected from the supply voltage irrespective of any
other units connected to SIMOLINK, you have to use the external
voltage supply.

Terminal assignment at connection X470
The SIMOLINK bus system can only function if all the nodes are
operating.This requires that all nodes are always connected to a
voltage supply. If one of the nodes on SIMOLINK is not operating,
SIMOLINK is interrupted.
DC supply cables
Operation of unshielded DC supply cables
(e. g. 24 V infeed for external current supply):
• DC supply cables: Length max. 10 m permissible
In the case of longer cables a suitable overvoltage protection device
must be connected by the user, e.g. following type:
