PROFINET
10.1
Overview
The DCR 248i code reader is designed as a modular field device and is a PROFINET-IO device that com-
municates cyclically with the assigned PROFINET-IO controller during operation.
The device can be operated as a single device (standalone) with individual device name in a PROFINET-
IO star or tree topology. The control must communicate this device name to the participant during the de-
vice naming (see chapter 10.3 "Configuring for the Siemens SIMATIC-S7 control").
Performance characteristics
The device has the following performance characteristics:
• A GSDML file is available for the device description
• The device family is certified as a PROFINET-IO device according to V2.32
• PROFINET-IO with real-time (RT) communication
• Standard Fast Ethernet (100 Mbit/s) connection (M12 technology)
• Auto-crossover and auto-negotiation
• Cyclical data exchange
• 4-pin, M12 connectors with D-coding are used for the electrical connection
• Identification & maintenance functions (I&M) IM0 – IM4
• The IP address – or name assignment – is set using, e.g., the Siemens STEP7 or TIA development en-
vironment or comparable tools
• Cycle time: maximum 4 ms (
MinDeviceInterval
=128)
• Function range acc. to Conformance Class B
• Network load class I
Communication
Basic communication and integration takes place via the GSDML file (see chapter 10.2 "GSDML file"). The
modules of the GSDML file do not support any configuration of the device functionality. Configuration is
performed via other mechanisms, e.g., the webConfig tool or online/XML commands (see chapter 9 "Com-
missioning – Leuze electronic webConfig tool"; see chapter 11 "Interfaces – Communication").
Each device has a unique MAC address (Media Access Control) that is specified on the name plate. The
MAC address (MAC-ID) is linked to an IP address during the course of configuration. The MAC address
can be found on the name plate and on an easily removable "Address Link Label” (MAC address) that is
also attached to the device.
On delivery, the device is assigned the following network address:
• IP address: 192.168.60.101
• Subnet mask: 255.255.255.0
Electrical connection
The device features multiple M 12 connectors / sockets for the electrical connection of the supply voltage,
the interface and the switching inputs and outputs (see chapter 7 "Electrical connection").

GSDML file
The functionality of the DCR 248i via the PROFINET interface is defined with input/output data that is de-
fined in the modules of the GSDML file (see chapter 10.4 "PROFINET project modules").
A user-specific configuration tool is used during PLC program creation to integrate the required modules
and configure them appropriately for their respective use.
When operating the device on the PROFINET, all input/output data is occupied with default values. If this
input/output data is not changed by the user, the device operates with the default settings set by Leuze
electronic on delivery. The default settings of the device can be found in the module descriptions.
