Connecting the Operator Panels and I/O Devices
Introduction
The operator panels and I/O devices which can be connected to your M7-400
depend on its configuration.
Extensive information on all connection options of the M7-400 can be found in the
appropriate sections of the technical data.
To prepare for operation, you need either a PC/programming device or the M7-400
configuration with monitor, keyboard, expansion module, and mass storage module
as well as interface submodules.
For reasons of noise immunity of the entire system, we recommend that you use
the standard connecting cables available from Siemens for connecting the
I/O devices.
Note
If the monitor cable and connecting cables between the CPU and the keyboard or
printer, etc. are laid parallel to high-voltage lines, screen interference and
interruptions in the M7-400 complete system may occur.
You should not lay the monitor cable and connecting cables between the M7-400
and the keyboard or printer, etc. parallel to high-voltage lines.
If necessary, install a separate cable rack with a minimum clearance of 50 cm from
the power cables.
Connecting the VGA Monitor Locally
To be able to connect a VGA monitor locally to the central rack, you must insert an
interface submodule IF 962-VGA in the submodule slot of the central rack or in one
of the corresponding expansion racks. Connect the monitor to the 15-pin
high-density subminiature D female connector of the IF 962-VGA interface
submodule (up to 2.5 m).
Connecting the Keyboard
Connect the keyboard to the 6-pin mini-round socket of the interface submodule
IF 962-VGA.
