The Interface module IM154- 8 PN/DP CPU with CPU functionality is based on the S7-300 CPU 315-2 PN/DP and offers the same quantity structures and functions.
The fail-safe interface module IM154-8FX PN/DP F-CPU is available for safety-related applications.
The IM154-8 PN/DP CPU as well as the fail-safe variant has two communication interfaces,
The IM 154-8 PN/DP CPU supports both PROFINET IO (up to 128 IO devices can be connected) and PROFINET CBA, as well as PROFIBUS DP (as master for up to 124 slaves).
Furthermore, a web server functionality for information, status, diagnostics, clock synchronization via the Ethernet (NTP) is available. The open Ethernet communication (TCP/IP, UDP, ISO-on-TCP) permits reliable and high-speed data exchange.
Isochronous mode is possible on the PROFIBUS. There is less loading on the central controller because individual plant sections can be configured, commissioned, diagnosed and operated individually.
