5.2 Fields of application
The brief overview below describes the solutions required of the TPM 478-2
module. The module is optional to the PCS7/TM PLC
and offers the following solutions:
• Connection of TELEPERM M I/O hardware
(via TPM 478-2 and migration rack).
To operate your PLC with TELEPERM M I/O, you require the TPM 478-2
module. The PLC and the TPM 478-2 are installed in a so-called migration
rack.
TPM 478-2 delivers the process image of your configured I/O modules to the
TELEPERM M I/O bus. The module is equipped with two I/O bus interfaces
for interconnecting TELEPERM M basic/expansion cabinets, as well as with
a +5 V bus.
The migration rack is designed for optimal arrangement of the module inter-
faces in the cabinet, according to TELEPERM M regulations. The rack di-
rectly replaces the previous PLC basic unit in the cabinet.
Special advantage is the complete mechanical preassembly for installation in
the cabinet.
Caution
A PCS7/TM in the migration rack cannot be used to replace redundant
AS 220H or AS 235H systems.
Compact systems AS 220K, AS 230K, AS 235K cannot be replaced by a
PCS7/TM in their existing cubicles. In this case the assembly is carried out
as in a migration from AS 220/230.
Details on the migration rack are found in the description /32/.
The TPM 478-2 interface module offers:
• an interface to the TELEPERM M I/O bus
• I/O functions compatible to the TELEPERM M I/O interface
• ISA bus interface of FM456-4
• Diagnostic display for TELEPERM M I/O modules
• process image controlling
• implementation of two TELEPERM M I/O busses A and B
• interface connection via bus connector to TELEPERM M I/O bus sy-
stems of the basic/expansion cabinet
• ”+5 V bus” interface for the supply of TELEPERM M expansion modules
(cabinet connections)
