3 Safety
3.1 Intended use
The expansion module PNOZ mc4p is used for communication between the configurable
safety system and DeviceNet.
DeviceNet is designed for fast data exchange at field level. The expansion module PNOZ
mc4p is a passive DeviceNet subscriber (Slave). The basic communication functions with
DeviceNet meet the requirements of the DeviceNet specification, Release 2.0. The central
controller (master) 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, the expan-
sion module PNOZ mc4p can also be used for diagnostic and commissioning functions.
Data traffic is monitored on the Master/Slave side.
The expansion module may only be connected to a base unit from the configurable system
PNOZmulti (please refer to the document "PNOZmulti System Expansion" for details of the
base units that can be connected).
The configurable system PNOZmulti is used for the safety-related interruption of safety cir-
cuits and is designed for use in:
}Emergency 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 [ 19]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
3.2 System requirements
Please refer to the "Product Modifications PNOZmulti" document in the "Version overview"
section for details of which versions of the base unit and PNOZmulti Configurator can be
used for this product.

4 Function description
4.1 Operation
The virtual inputs and outputs that are to be transferred via DeviceNet are selected and
configured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mc4p are connected via a jumper. The expansion module PNOZ mc4p is also supplied with
voltage via this jumper.
The station address and the transmission rate are set using DIP switches. After the supply
voltage is switched on or the PNOZmulti control system is reset, the expansion module
PNOZ mc4p is configured and started automatically.
LEDs indicate the status of the expansion module on DeviceNet.
The configuration is described in detail in the PNOZmulti Configurator's online help.
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 notches on the rear of the unit to attach it to a mounting rail. Connect the con-
trol 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 PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details, otherwise air conditioning will be required.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
CAUTION!
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
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 mc4p is configured and started automatically. The LEDs
“MS” and “NS” display the status of the PNOZ mc4p on DeviceNet.
If the expansion module PNOZ mc4p does not receive a configuration from the base unit
for a period of 30 s, the fieldbus module PNOZ mc4p connects to DeviceNet and "Online"
status is displayed on DeviceNet. The "MS" LED flashes red.
