The IM 154-8 PN/DP CPU can be used simultaneously as an IO Controller and as an I-Device on PROFINET via the integral PROFINET interface. The intelligent 154-8 CPU interface module has integrated PLC functionality. The functions included correspond to those of the S7-300 CPU 315-2 PN/DP.

The ET 200pro can use these PLC functions to control autonomous technological functional units, e.g.,

• Conveyor systems, switches
• Lifting stations
• Positioning tasks
• Thanks to its PROFIBUS interface in addition to the PROFINET interface, the IM 154-8 PN/DP also offers the option of operating other distributed I/Os via PROFIBUS. The IM 154-8 PN/DP CPU can be used on PROFIBUS not only as a master but also as a slave. The CPU's potential applications are therefore extended manufacturing cells with preprocessing, whereby stand-alone operation is also an option. Cabinet-free installations are possible due to the high IP67 rating.
