The CP 1543SP-1 is used for connecting the ET 200 SP Distributed Controller to Industrial Ethernet networks. With its own processor, it relieves the CPU of communication tasks.

The CP 1543SP-1 offers possible communication with:

• PGs/PCs
• Master computers
• Operator control and monitoring systems
• SIMATIC S7 systems

It can be used to protect the ET 200 SP Distributed Controller automation system from unauthorized access from an Ethernet network. The CP 1543SP-1 allows secure remote access via a LAN and enables the data transfer between devices or network segments to be protected from data manipulation/espionage.
