Siemens 6ES7155-5BA00-0AB0 ET 200MP IM 155-5 DP ST PROFIBUS Interface Module

The Siemens 6ES7155-5BA00-0AB0 is a SIMATIC ET 200MP PROFIBUS interface module (IM 155-5 DP ST) that connects up to 12 S7-1500 I/O modules to a PROFIBUS DP master through a single RS 485 port at up to 12 Mbit/s. It runs from a 24 V DC supply and ships with the PROFIBUS connection plug 6ES7972-0BB70-0XA0 included.

Technical Specifications

Selection Notes

The ST (Standard) designation means this interface module covers standard-speed PROFIBUS DP connectivity for up to 12 S7-1500 modules without the extended IRT diagnostics of a PROFINET HF variant - choose it when the station only needs cyclic DP data exchange and DPV1 acyclic parameterization on a PROFIBUS, not PROFINET, network. PROFIsafe support lets F-modules run in the same rack for fail-safe I/O over the same DP segment. The RS 485 port tops out at 12 Mbit/s, so segment length and repeater count on the DP trunk should be checked against that rate before scaling toward the 12-module limit.

Applications

Head module for a PROFIBUS DP-based ET 200MP station carrying up to 12 S7-1500 I/O modules, including fail-safe PROFIsafe I/O, on plants standardized on PROFIBUS rather than PROFINET.
