Starting up the device - Configuration
8.3.11 UDP
The bar code reader requires from the user the IP address and the port number of the communication part-
ner. In the same way, the host system (PC/PLC) also requires the set IP address of the bar code reader
and the selected port number. By assigning these parameters, a socket is formed via which the data can
be sent and received.
Ä Activate the UDP protocol
Ä Set the following values:
• IP address of the communication partner
• Port number of the communication partner
The corresponding adjustment options can be found in the webConfig tool under Configuration > Com-
munication > Host communication.
All other parameters required for the reading task, such as setting the code type and number of digits, etc.,
are set using the engineering tool of the PLC with the aid of the various available modules (see chapter 8.4
"Commissioning via the PROFINET-IO").

Commissioning via the PROFINET-IO
8.4.1
General information
The BCL 248i is designed as a modular field device. The PROFINET-IO functionality of the device is de-
fined via parameter sets that are combined in modules (slots) and sub-modules (sub-slots). The further ad-
dressing within subslots is then accomplished via an index. The modules are included in a XML-based
GSD file, which is supplied as an integral part of the device. By using a user-specific configuration tool,
such as, e.g. SIMATIC Manager for the Siemens PLC, the required modules are integrated into a project
during commissioning and its settings and parameters are configured accordingly. These modules are pro-
vided by the GSD file.
NOTICE
All input and output modules described in this documentation are described from the viewpoint
of the control (IO controller):
- Input data arrives at the control.
- Output data is sent out by the control.
Detailed information on how to prepare the control and the GSD file see chapter 8.3 "Configuration steps
for a Siemens Simatic S7 control".
For the default settings of the BCL 248i, please refer to the following module descriptions.
NOTICE
Ä Please note that the set data is overwritten by the PLC. Some controls make available a so-
called "universal module". This module must not be activated for the BCL 248i.
From the perspective of the device, a distinction is made between PROFINET‑IO parameters and internal
parameters. PROFINET-IO parameters are all parameters that can be changed via the PROFINET-IO and
are described in the following modules. Internal parameters, on the other hand, can only be changed via a
service interface and retain their value even following a PROFINET-IO configuration.
During the configuration process, the BCL receives parameter telegrams from the IO controller (PLC). Be-
fore this is evaluated and the respective parameter values are set, all PROFINET‑IO parameters are reset
to default values. This ensures that the parameters of modules that are not selected are set to the default
values.
