!
WARNING
There is a potential danger that connectors X1 and X3 are
interchanged (both connectors are sub-D 9 socket connectors).
An expansion module (EXM438-1 or EXM 448/EXM 448-2) can be
inserted at this 5 x 24-pin socket connector.
Two 5 x 17-pin socket connectors are the connectors on SIMATIC S7
backplane bus. K-bus connection
A 5 x 7-pin socket connector is provided to connect to the
SIMATIC K bus.
The terminals for the binary inputs are available via the interface
modules.
Interface modules Function
SB10, SU12 Electrical 1:1 connection, no signal conversion
SB61 With electrical isolation and signal conversion
Refer to Catalog ST DA for information on the interface modules.
NOTE
The operation of the FM 458-1 DP is only allowed with these interface
modules.
The interface modules are “open type” and therefore only can be
installed in closed switch cabinets or switch rooms.
