3 Safety
3.1 Intended use
The expansion module PNOZ m ES Profibus is used for communication between the con-
figurable control system PNOZmulti 2 and PROFIBUS-DP.
PROFIBUS-DP is designed for fast data exchange at field level. The expansion module
PNOZ m ES Profibus is a passive subscriber (Slave) of PROFIBUS-DP (DPV0). The basic
functions of communication with PROFIBUS-DP conform to EN 50170. The central control-
ler (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, PROFIBUS-DP
can also be used for diagnostics 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 2 (please refer to the document "PNOZmulti System Expansion" for details of
the base units that can be connected).
The configurable system PNOZmulti 2 is used for the safety-related interruption of safety
circuits 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 [ 21]).
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

4 Function description
4.1 Operation
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 modulePNOZ
m ES Profibus are connected via a jumper.
The station address is set via rotary switches. After the supply voltage is switched on or the
control system PNOZmulti2 is reset, the expansion module PNOZ m ES Profibus is con-
figured 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 Data access
The data is structured as follows:
}Virtual data
– Input area PNOZ m ES Profibus
The values for the inputs are set in the Master as an output and transferred to the
PNOZmulti 2.
– Output area PNOZ m ES Profibus
The outputs are configured in the PNOZmulti Configurator and transferred to the
Master.
}Status of LEDs:
Bits 0 … 4: Status of LEDs on the PNOZmulti 2
– Bit 0: OFAULT
– Bit 1: IFAULT
– Bit 2: FAULT
– Bit 3: DIAG
– Bit 4: RUN
}Data exchange is displayed in Bit 5.
}Polling the payload data: 2 Bytes with the table number and segment number are sent
by the Master for access to the payload data table (15 Bytes are returned to the Mas-
ter).
Detailed information on data exchange (tables, segments) is available in the document
"Communication Interfaces" in the section entitled "Fieldbus modules".

4.3 Assigning the inputs/outputs in the PNOZmulti Configurator
to the PROFIBUS-DP inputs/outputs
Virtual inputs and outputs can be requested or set directly via the following objects. Each
element can be selected individually in the master control system, e.g. virtual inputs i0-31.
The data width is also established this way.
Input data
The Master writes to the virtual inputs of the PNOZmulti 2.
Description Input data from PNOZmulti 2
Virtual inputs i0 – i31 4 Input Bytes
Virtual inputs i32 – i63 4 Input Bytes
Virtual inputs i64 – i95 4 Input Bytes
Virtual inputs i96 – i127 4 Input Bytes
Output data
The Master reads the virtual outputs of the PNOZmulti 2.
Description Output data from PNOZmulti 2
Virtual outputs o0 – o31 4 Output Bytes
Virtual outputs o32 – o63 4 Output Bytes
Virtual outputs o64 – o95 4 Output Bytes

5 Installation
5.1 General installation guidelines
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Fit the safety system to a horizontal mounting rail. The venting slots must face upward
and downward. Other mounting positions could damage the safety system.
}Use the locking elements on the rear of the unit to attach it to a mounting rail.
}In environments exposed to heavy vibration, the unit should be secured using a fixing
element (e.g. retaining bracket or end angle).
}Open the locking slide before lifting the unit from the mounting rail.
}To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
}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.
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.

7.1 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 m ES Profibus is configured and started automatically. The
"ONLINE" and "OFFLINE" LEDs indicate the status of the PNOZ m ES Profibus on
PROFIBUS-DP.
If the expansion module PNOZ m ES Profibus does not receive a configuration from the
base unit for a period of 30 s, the expansion module PNOZ m ES Profibus connects to
PROFIBUS-DP and the "ONLINE" status is displayed on the PROFIBUS-DP. The error
message "No Connection with Base Module" is sent to the Master.
