Note
You install, wire and fuse the PCS7/TM by yourself. We provide the migra-
tion rack (refer to the section below) for easy installation and use of the mo-
dules. Details on PCS7/TM and migration racks, as well as connectable
hardware I/O modules are found in descriptions /2/ and /4/.
The migration rack is a preassembled module rack equipped with an integra-
ted SIMATIC S7/M7-400 backplane bus, and with dimensions according to
the installation system ES 902 used in TELEPERM M cabinet systems. It
holds the configuration described in Figure 5-5 and is equipped with ready-
to-use cables and integrated fusing for L+ 24 V/16 A. I/O bus A and B can be
connected at the rear of the migration rack with the help of the two ribbon
cable connectors.
TPM 478-2 in the migration rack processes I/O bus A and B on which you
can operate up to seven TELEPERM M expansion units EU (3 on A; 4 on B)
or up to eight ES 100 K expansion systems (4 on A, 4 on B). Expansion units
and ES 100 K systems can also be operated on both I/O bus systems in mixed
mode, with max. 4 EU/ES per I/O bus).
Typical configurations are:
• 3 EU and 1 ES 100 K per I/O bus A and B
• at least 1 EE, and thus up to 3 ES 100 K on bus A and B
• 3 EUs of an AS 230-/AS 235 basic cabinet on bus A and 3 EU of an
AS 230-/AS 235 expansion cabinet on bus B (se Figure 5-5).
