Siemens has added a new interface module with CPU functionality to the Simatic ET200S product family of distributed I/O devices: the IM151-8 PN/DP CPU handles control tasks and communications functions via Profinet. The module is also available in the fail-safe version IM151-8 PN/DP F-CPU.
With the new IM151-8 PN/DP CPU module that has the performance power of a Simatic S7-300 CPU 314, users can implement distributed structures on Profinet. The Profinet communication interface with three ports for linear bus topologies and programming device functions is onboard and can be expanded with a Profibus DP master module. As a Profinet IO Controller, the new interface module supports the real-time properties RT (Real Time) and IRT (Isochronous Real Time) and can control up to 128 IO Devices. Since it supports other open TCP/IP-based communication methods, the flexible module is also available for other application options.
