3 Safety
3.1 Intended use
The expansion module PNOZ mc3p is used for communication between the configurable
control system PNOZmulti and PROFIBUS-DP.
PROFIBUS-DP is designed for fast data exchange at field level. The expansion module
PNOZ mc3p is a passive subscriber (Slave) of PROFIBUS-DP (DPV0). The basic functions
of communication with PROFIBUS-DP conform to EN 50170. The central controller (Mas-
ter) reads input information from the slaves and writes output information to the slaves as
part of each cycle. As well as the cyclical transfer of usable data, PROFIBUS-DP can also
be used for diagnostics and commissioning functions. Data traffic is monitored on the Mas-
ter/Slave side.
The expansion module may only be connected to a base unit from the PNOZmulti system
(please refer to the document "PNOZmulti System Expansion" for details of the base units
that can be connected).
The configurable small control systems PNOZmulti are used for the safety-related interrup-
tion of safety circuits and are designed for use in:
}E-STOP equipment
}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1
The expansion module may not be used for safety-related functions.
The following is deemed improper use in particular
}Any component, technical or electrical modification to the product,
}Use of the product outside the areas described in this manual,
}Use of the product outside the technical details (see Technical details [ 21]).
NOTICE

4 Function description
4.1 Functions
The virtual inputs and outputs that are to be transferred via PROFIBUS are selected and
configured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mc3p are connected via a jumper. The expansion module PNOZ mc3p is also supplied with
voltage via this jumper.
The station address is set via rotary switches. After the supply voltage is switched on or the
PNOZmulti control system is reset, the expansion module PNOZ mc3p is configured and
started automatically.
LEDs indicate the status of the expansion module on PROFIBUS.
The configuration is described in detail in the PNOZmulti Configurator's online help.
INFORMATION
The GSD file is available on the Internet at www.pilz.de.
4.2 Input and output data
The data is structured as follows:
}Input area
The inputs are defined in the master and transferred to the PNOZmulti. Each input has
a number, e.g. input bit 4 of byte 1 has the number i12.
}Output range
The outputs are defined in the PNOZmulti Configurator. Each output that is used is
given a number there, e.g. o0, o5... The status of output o0 is stored in bit 0 of byte 0;
the status of output o5 is stored in bit 5 of byte 0 etc.
}Output range only: Byte 3
Bits 0 … 4: Status of LEDs on the PNOZmulti
– Bit 0: OFAULT
– Bit 1: IFAULT
– Bit 2: FAULT
– Bit 3: DIAG
– Bit 4: RUN
Bit 5: Data is being exchanged.
Detailed information on data exchange (tables, segments) is available in the document
"Communication Interfaces" in the section entitled "Fieldbus modules".

5 Installation
5.1 General installation guidelines
}The control system should be installed in a control cabinet with a protection type of at
least IP54. Fit the control system to a horizontal mounting rail. The venting slots must
face upward and downward. Other mounting positions could destroy the control system.
}Use the locking elements on the rear of the unit to attach it to a mounting rail. Connect
the control system to the mounting rail in an upright position, so that the earthing
springs on the control system are pressed on to the mounting rail.
}The ambient temperature of the devices in the control cabinet must not exceed the fig-
ure stated in the technical details. Air conditioning may otherwise be required.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.

7 Operation
7.1 Messages
When the supply voltage is switched on, the PNOZmulti safety system copies the configur-
ation from the chip card.
The LEDs “POWER”, “DIAG”, “FAULT”, “IFAULT” and “OFAULT” will light up on the base
unit.
The expansion module PNOZ mc3p is configured and started automatically. The "ONLINE"
and "OFFLINE" LEDs indicate the status of the PNOZ mc3p on PROFIBUS-DP.
If the expansion module PNOZ mc3p does not receive a configuration from the base unit
for a period of 30 s, the expansion module PNOZ mc3p connects to PROFIBUS-DP and
"ONLINE" status is displayed on PROFIBUS-DP. The error message "External Error" is
sent to the Master.
