Fieldbus systems
Various product variants of the BCL 500
i
series are available for connecting to different
fieldbus systems such as PROFIBUS DP, ProfiNet and Ethernet.
4.5.1
PROFIBUS DP
The BCL 504
i
is designed as a PROFIBUS device (PROFIBUS DP-V1 acc. to IEC 61158)
with a baud rate of max. 12MBd. The functionality of the device is defined via parameter sets
which are clustered in modules. These modules are contained in a GSD file.
The BCL 504
i
barcode readers can be operated as network devices on the PROFIBUS. The
BCL 504
i
features multiple M12 connectors / sockets for the electrical connection of the
supply voltage, the interface and the switching inputs and outputs.
The BCL 504
i
supports:
• PROFIBUS-DP slave functionality.
• Modular structure of the IO data
• Automatic baud rate detection up to 12 Mbit/s
• SYNC/FREEZE
• FailSafe Mode
• Device-specific diagnostic data
• I&M
• No changing of the slave address via the PROFIBUS
For further details, see chapter 10!

Heater
For low-temperature applications to min. -35°C (e.g. in cold storage), the barcode readers
of the BCL 504
i
series can optionally be permanently fitted with a built-in heating and these
barcode readers purchased as separate device models.
