SCALANCE XF-200BA DNA (Y-Switch)
PROFINET for process automation
The industrial Ethernet switch SCALANCE XF204-2BA DNA (Dual Network Access) enables integration of S2 devices in a high-availability PROFINET system (R1 system) via what is termed as Y-Switch functionality.
Two ports of the Y-Switch enable the connection of S2 devices using the media redundancy method, MRP. This can be implemented selectively via copper or fiber optic in a ring structure.
The two other ports establish the network connection from the Y-Switch to a high-availability R1 system.
Y-switch functionality additionally increases the availability of a process plant and helps avoid plant standstills.
The BA 2xRJ45VD HA BusAdapter is capable of both standard Ethernet communication via 4-wire cables (twisted pair) and data transfer via 2-wire cables (single twisted pair). This means existing PROFIBUS DP infrastructures can continue to be used, thereby avoiding costly retrofitting at the field level in particular.
High availability of process plants
NAMUR NE 21-compliant
High level of flexibility due to use of bus adapters
Can be used in process automation thanks to conformal coating, extended temperature range (-40 °C to +70 °C) and extended installation altitude of 4000 m
Space savings due to slim design based on SIMATIC ET 200SP
