Siemens SIMATIC DP Series PLC CPU for Use with ET 200SP, 24 V Supply, 20-Input

Use this efficient entry-level CPU (central processing unit) from Siemens for production technology applications with medium processing and response-speed requirements. It's suitable to use as a PROFINET I/O (input/output) controller or as a distributed intelligence device with the ability to pre-process data locally and deliver relevant data to a higher-level PLC (programmable logic controller). This allows for faster setup, quicker response times to critical signals and a reduced load on the central PLC. The CPU offers comprehensive control functions via easy-to-configure blocks, as well as the ability to connect drives using standardised PLC open blocks.

• Less load on the bus system due to smaller data volumes
• Operates independently of a PLC and will continue to run if a PLC fails for enhanced system control
• Powerful processor that offers command execution times as low as 72ns per binary instruction
• Flexible bit-modular design allows for maximum flexibility and a functionally orientated station setup

The unit is designed as a 3-port switch to allow for a linear topology set-up via port one and two. A programming device, such as a personal computer, can be conveniently connected to the third port.
