The CPU 1516pro-2 PN is the CPU with a large program and data memory for demanding tasks in applications that also contain distributed automation structures alongside central I/O and require protection level IP 65/67.

It can be used as a PROFINET IO Controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 3-port switch so that a linear topology can be set up in the system.

The additional integrated PROFINET IO RT interface with separate IP address can be used, for example, for network separation to operate additional PROFINET IO devices.

In addition, the CPU offers comprehensive control functionalities as well as the ability to connect drives via standardized PLC-open blocks.

The ET 200pro system with the CPU 1516pro-2 PN can be used for controlling autonomous technological functional units, e.g.:

• Conveyor systems, switches
• Lifting stations
• Positioning tasks
• Workstations in the powertrain segment of the automotive industry

The CPU's potential applications are therefore extended manufacturing cells with preprocessing, where stand-alone operation is also an option. Cabinet-free installations are possible due to the high IP67 degree of protection.
