4.5.3.2 Configuring for S7 control and SIMATIC FM 458 application module

The following function blocks must be configured for the coupling
between an S7 control and an SIMATIC FM 458 application module via P
bus:
• SIMATIC FM 458 application module:
• S7 control:
Each table may only contain values associated with one particular data
type. If several tables with different data types are to be managed, then
an TAB or TAB_D must be configured for each table.
WR_TAB is used to transfer the tabular values from SIMATIC DB to
function blocks TAB and TAB_D. The tabular values are transferred using
a data telegram. When the last data telegram has been transferred, the
TAB or TAB_D is automatically signaled that all of the tabular values have
been transferred and that the table should be activated. WR_TAB
receives a checkback signal as to whether activation was successful or
not. After the table was successfully activated, its address is output at the
TAB output of the TAB or TAB_D.
TAB and TAB_D TAB and TAB_D should be configured as follows:
They should be configured in a sampling time greater than or equal to
32ms. The following connection settings are required:
If a communications interface is configured at the CTS connection, it is
