IM 151-8 PN/DP CPU Siemens

Область применения

The IM 151-8 PN/DP CPU can be used for remote, distributed automation solutions with average programming complexity. It enables remote preprocessing of the process data on site and only transmits required data to the higher-level control unit. This results in the following advantages:

• Relieves the central control unit
• Short response times to critical signals on site
• Low data volume relieves bus system
• Pretested units and parallel commissioning enable faster set-up
• Autonomous machine units increase availability and flexibility
• Clear configuration processes

The IM 151-8 PN/DP CPU operates completely independent of the central control unit. If it fails, the IM 151-8 PN/DP CPU simply continues to run.

The bit-modular design of the ET 200S I/O system together with the IM 151-8 PN/DP CPU enable functionally oriented station design.
