The Siemens 6ES7545-5DA00-0AB0 is the CM PROFIBUS
DP communications module for a SIMATIC ET 200SP CPU. It adds a PROFIBUS DP
interface using RS-485 and can operate as a PROFIBUS DP master or device. As a
DP master, it supports up to 125 DP devices. As a PROFIBUS DP device, the
interface supports transmission rates up to 12 Mbit/s, automatic baud-rate
search and a maximum address area of 120. The module provides 244 bytes of
input and 244 bytes of output transfer memory and supports PG/OP communication,
routing, S7 communication, direct data exchange and DPV1. It operates from 24 V
DC, includes reverse-polarity protection and provides diagnostic functions
through a green/red DIAG LED. The module measures 35 × 117 × 75 mm and weighs
approximately 80 g.

5. Product Highlights
The CM PROFIBUS DP provides a dedicated PROFIBUS interface
for ET 200SP CPU systems. Its ability to function as a DP master or device,
support up to 125 DP devices as master and communicate at up to 12 Mbit/s makes
it suitable for integrating PROFIBUS-based field equipment with modern SIMATIC
ET 200SP architectures.
6. Important Ordering & Installation Information
The exact article number is 6ES7545-5DA00-0AB0. The
module is designed for the ET 200SP CPU platform and uses an RS-485 PROFIBUS DP
interface with a 9-pole D-sub connection. Siemens specifies STEP 7/TIA Portal
configurability from V13 Update 3. Verify the ET 200SP CPU compatibility,
PROFIBUS configuration and required connector/cabling before installation.
Always follow the manufacturer's official installation,
wiring, commissioning and safety instructions.
