3.18.1.2 Overview, "Automatic mode: Communications"
In the "Automatic mode: Communications", tabular values can be
transferred using the following communication versions:
• S7 via the P bus for SIMATIC FM 458 (it is necessary to additionally
configure the WR_TAB on the control side)
• TCP/IP (tabular values can be transferred from a SIMATIC TDC
module to another one using the CTV and CRV FBs)
• DUST1 (tabular values can only be transferred via a DUST1 interface)
The tabular values are transferred using data telegrams.
The following diagram illustrates the principle procedure in the "Automatic
mode: Communications" for transferring tables from an S7 control to a
SIMATIC FM 458 application module via the P bus:
