Fieldbus systems
Various product variants of the BCL 500
i
series are available for connecting to different
fieldbus systems such as PROFIBUS DP, PROFINET-IO and Ethernet.
4.5.1
PROFINET-IO
The BCL 548
i
is designed as a PROFINET-IO device (acc. to IEEE 802.3). It supports a trans-
mission rate of up to 100 Mbit/s (100Base TX/FX), full duplex, as well as auto-negotiation
and auto-crossover.
The functionality of the device is defined via parameter sets which are clustered in modules.
These modules are contained in a GSDML file.
Each BCL 548
i
is sealed with a unique MAC-ID. This information is used to assign a unique,
plant-specific device name ("NameOfStation") to the device via the "Discovery and Config-
uration Protocol (DCP)". When configuring a PROFINET-IO system, the assignment of the
device names to the configured IO devices creates a name-based relationship for the partic-
ipating IO devices ("device naming"). Further information can be found in section "Commis-
sioning and configuration" on page 116.
The BCL 548
i
features multiple M12 connectors / sockets for the electrical connection of
the supply voltage, the interface and the switching inputs and outputs. Additional informa-
tion on the electrical connection can be found in chapter 7.
The BCL 548
i
supports:
• PROFIBUS-IO device functionality based on the PROFIBUS profile for identification
systems
• Modular structure of the IO data
• PROFINET-IO RT (

• Standard Fast Ethernet (100 Mbit/s) connections (M12 technology)
• Integrated Ethernet switch/ 2 Ethernet ports
• PROFINET-IO Conformance Class B (CC-B)
• I&M support: I&M 0-4
• Diagnostics/alarms
