1.1 Interface module TPM 478-2
TPM 478-2 is an interface module with the M7-400 technological structure
of the SIMATIC M7 product family. It represents an expansion unit for the
central module FM 456-4, and it is used in the PCS7/TM PLC.
The following functions are integrated in the TPM 478-2 interface module:
• TELEPERM M I/O functionality.
A highly efficient processor controls the access functions to TELE-
PERM M I/O modules via a periodically updated process image. This
process image fetches input process data it writes them to the outputs of
the hardware I/O.
Process image data is transferred from the TPM 478-2 to the user pro-
gram via driver blocks.
• two I/O bus interfaces for the TELEPERM M basic and expansion cabinet
• I/O bus logic supply with a +5 V bus.
The TPM 478-2 interface module interconnects existing TELEPERM M I/O
hardware of the basic and expansion cabinet of an AS 220/230/235 system.
Here, the basic central unit is replaced with a preinstalled module rack - na-
mely the migration rack - which contains a system PCS7/TM and the add-on
components TPM 478-2 and FM456-4.
It provides the I/O bus connections A and B for existing expansion units.
Data are exchanged with existing expansion unit via I/O bus A and B of
TPM 478-2. See Figure 1-1.
