Configuration steps for a Siemens Simatic S7 control
The following steps are necessary for commissioning with a Siemens S7 control:
1. Preparation of the control system S7 PLC
2. Installation of the GSD file
3. Hardware configuration of the S7 PLC
4. Transmission of the PROFINET-IO configuration to the IO controller (S7 PLC)
5. Device naming
• Configuration of the device name
• Device naming
• Assigning the device names to the configured IO devices
• Assignment of MAC address – IP address – individual device names
6. Check device name
8.3.1
Step 1 – Prepare the control
The first step involves the assignment of an IP address to the IO controller (S7 PLC) and the preparation of
the control for consistent data transmission.
NOTICE
Ä With the S7 control, make sure that at least Simatic Manager Version 5.4 + Service Pack 5
(V5.4+SP5) is used.
8.3.2
Step 2 – Installing GSD file
For the subsequent configuration of the IO devices, e.g., BCL 248i, the corresponding GSD file must be
loaded first. In this file, all data necessary for operating the BCL 248i is described in modules. These are in-
put and output data and device parameters for the functioning of the BCL 248i and the definition of the con-
trol and status bits.
GSD files
The term GSD stands for the textual description of a PROFINET-IO device model. For this purpose, the
XML-based GSDML (Generic Station Description Markup Language) was introduced. In the following, the
terms "GSD" or "GSD file" always refer to the GSDML-based format.
The GSDML file can support an arbitrary number of languages in one file. Every GSDML file contains a
version of the BCL 248i device model. This is also reflected in the file name.
File name structure
The file name of the GSD file is constructed according to the following rule:
GSDML-[GSDML-schema version]-Leuze-BCL248i-[Date].xml
Explanation:
• GSDML schema version:
Version identifier of the GSDML schema version used, e.g., V2.2
• Date:
Release date of the GSD file in the format yyyymmdd.
This date also stands for the release date of the file.
Example:
GSDML-V2.2-Leuze-BCL248i-20090503.xml
The GSD file is located directly in the product area under Downloads, i.e., for the BCL 248i:
www.leuze.com > Products > Identification > Bar code identification > Stationary bar code readers >
BCL 200i > BCL 248i... > Downloads > Software/Driver
If parameters are changed in the project tool, for example, these changes are stored by the PLC in the
project, not in the GSD file. The GSD file is a certified and integral part of the device and must not be
changed. The file is not changed by the system either.
