Design of the modular safety sys-
tem
The modular safety system consists of
the base unit and expansion modules.
The base unit itself has
20 inputs
2 relay outputs
4 semiconductor outputs
1 auxiliary output, which is required
for deleting the configuration data
in the base unit
1 cascading input
1 cascading output
The number of inputs and outputs can
be increased at any time using the ex-
pansion modules. The modules are
linked via a jumper. The system is con-
figured using the PNOZmulti Configu-
rator. Special expansion modules
enable data to be exchanged via a
fieldbus (non-safety-related) or safe
speed monitoring, for example.
Operation of the units
The PNOZmulti Configurator gener-
ates a project file which is downloaded
to the base unit; there it defines:
Which safety functions the inputs
are to carry out, e.g. E-STOP moni-
toring, safety gate monitoring
How the inputs are connected to
the outputs via logic functions
Which output is configured (semi-
conductor, relay)
The units react the same, irrespective
of these functions:
If the start-up condition of the specific
safety function is met, there will be a
high signal at the output "Out1". The
output signal can be linked via a logic
function and is then present as the
"Out2" signal at the output on the
PNOZmulti unit.

Fieldbus modules
The fieldbus modules are used to
Read the diagnostic data
Set virtual inputs for standard func-
tions
Read virtual outputs for standard
functions
RS 232 interface
The base unit has an RS 232 interface
to
Download the project
Read the diagnostic data
Set virtual inputs for standard func-
tions
Read virtual outputs for standard
functions
Safety functions
The safety system has inputs and out-
puts, which can be used for safety
functions. The PNOZmulti safety sys-
tem can be configured to monitor
E-STOP pushbuttons
Operating mode selector switches
Enable switches
Two-hand buttons
Safety gates
Light curtains
Light beam devices
Speeds
Analogue input signals
Safety mats
Muting
Mechanical presses
Standstill
Various switch types are available for
the required safety-related applica-
tions. With some switch types it is
possible to monitor for simultaneity
(see chapter on "Configuration and
Wiring").
Standard functions
Expansion modules are available with
inputs and outputs for standard func-
tions.
Press applications
The PNOZ m2p base unit is designed
for applications on mechanical press-
es.
