To ensure BP monitoring of the MCP(s), the addresses must be specified as set in SDB 210 on the
1)
810D. The start address is set via SDB 210 on the 810D. In the supplied SDB 210, the start address
is specified as IB 0 for input signals and QB 0 for output signals. If a different start address is
required, this must be specified using the STEP 7 Communication Configuration package.
To ensure BP monitoring of the HHU(s), the addresses must be specified as set in SDB 210 on the
