Product Overview
The EXM 448 expands an FM 458-1 DP application with a configurable PROFIBUS-DP interface and a slot for an approved MASTERDRIVES option module.
The integrated interface can be configured as a DP master or DP slave and supports Shared Input, SYNC and FREEZE functions. The LE bus provides fast data transfer between the FM 458-1 DP and its expansion modules, while the P bus supplies the module. A dedicated RS232 parameterization interface and two communication-status LEDs support setup and diagnostics.

Frequently Asked Questions
Which controller platform accepts 6DD1607-0EA0?
Install it as an expansion module for the FM 458-1 DP and preserve the rack and project configuration used by the existing application.
Can 6DD1607-0EA0 operate as either a PROFIBUS master or slave?
Yes; the interface is configurable for either operating mode, so the replacement must use the same role and bus parameters as the installed unit.
What network capacity should be considered for 6DD1607-0EA0?
The interface supports rates from 9.6 kbit/s to 12 Mbit/s and up to 127 slaves, subject to the engineered configuration.
Where should 6DD1607-0EA0 be installed?
Use it only inside a closed switch cabinet and keep the ambient temperature within the specified limit.
How can communication be checked on 6DD1607-0EA0?
Use the two front indicators to confirm the communication-interface state and bus activity, then compare the configured DP role and rate.
What limit applies to the external 5 V output on 6DD1607-0EA0?
The external load must not exceed 90 mA, and the output is not short-circuit proof.
What should be preserved before replacing 6DD1607-0EA0?
Back up the FM 458 configuration, PROFIBUS parameters, master or slave assignment, address data and any installed option-module settings.
Compatibility & Ordering Notes
Compatibility Checklist
- Use the module with the matching FM 458-1 DP hardware configuration and documented expansion-bus arrangement.
- Retain the PROFIBUS operating role, station address, transfer rate and telegram configuration during replacement.
- Verify the installed MASTERDRIVES option module and restore its application parameters from the approved project backup.
