Distributed Controller based on SIMATIC ET 200 pro

Control next to the machine in IP65/67

Via interface modules the ET 200 pro is connected to the bus system, either the proven fieldbus PROFIBUS or PROFINET the leading Industrial Ethernet Standard.
ET 200pro Interface Modules are offered with CPU functionality in standard or failsafe variants.

SIMATIC ET200pro CPU 1516pro

The ET 200pro distributed I/O system is being expanded with CPU 1516pro-2 PN and CPU 1516pro F-2 PN. The new CPUs are based on the S7-1500 CPU 1516-3 PN/DP and offer two PROFINET IO communication interfaces.

The CPUs 1516pro-2 PN Standard and Fail-safe have a PROFINET IO interface with three PROFINET ports. The three ports have the same properties. In addition, you can implement a ring redundancy (MRP or MRPD) with ports 1 and 2. Ports 1 and 2 with M12 cable gland, as known from the IM154-8 PN/DP CPUs, are connected to the CPU by means of a connection module. Port 3 is a RJ45 socket that is permanently integrated into the CPU enclosure behind a porthole.

The 1516pro-2 PN and 1516pro F-2 PN CPUs support PROFINET IRT through this PN interface and thus permit short, predictable response times, even faster, deterministic data exchange with IO devices and a high immunity to interference from non-real-time data communication.
