S7-300 PROFIBUS DP communication processor for master, slave and S7 services

The CP 342-5 adds a PROFIBUS DP interface to an S7-300 station and supports transmission rates from 9.6 kbit/s to 12 Mbit/s through a 9-pin Sub-D connector. Reliable replacement requires the CP configuration, DP address map and the program calls that exchange process data.

Exact-match checkConfirm the exact CP revision, rack and slot, external 24 V supply, PROFIBUS address and baud rate, DP master or slave role, configured slaves, address areas and the DP_SEND and DP_RECV block status before removal.

DP Guide

6GK7342-5DA03-0XE0 is a SIMATIC NET CP 342-5 for connecting an S7-300 station to PROFIBUS DP. It can operate as a DP master or DP slave and also supports S7 communication services, depending on the STEP 7 hardware configuration and user program.

A module exchange must preserve more than the bus connector. Keep the STEP 7 project, CP configuration data and the program version that calls DP_SEND and DP_RECV. Record the diagnostic buffer, normal LEDs and the external 24 V wiring.

Compatibility, installation and diagnostic checkpoints for the exact installed system.

Hardware project

Preserve the CP slot, operating role, station address, baud rate, bus profile and configured DP slave list.

Program interface

Record the DP_SEND and DP_RECV calls, logical addresses, data areas and status-word handling used by the CPU program.

Physical segment

Photograph the Sub-D connector, termination switch, shield bonding and the cable route to the next active station.

LED evidence

Record the RUN, STOP and BUSF pattern before shutdown and after the reviewed configuration is downloaded.

Status words

Evaluate DP_SEND and DP_RECV return values and the CP diagnostic buffer before treating missing data as a bus fault.

Controlled test

Commission one documented DP segment at a time and prove input, output and diagnostic behavior before enabling the machine.

FAQ

How can I verify that 6GK7342-5DA03-0XE0 is compatible with the installed S7-300 station?

Match the complete order number and hardware revision, then compare the CP slot, STEP 7 hardware configuration, external 24 V supply and PROFIBUS master or slave role. Confirm that the engineering system contains the required hardware support package.

What should be preserved before replacing 6GK7342-5DA03-0XE0?

Keep the complete STEP 7 project, CP configuration, PROFIBUS address and baud rate, slave list, input and output areas and the program blocks that call DP_SEND and DP_RECV. Record connector termination, normal LEDs and the diagnostic buffer.

Why can 6GK7342-5DA03-0XE0 show BUSF immediately after installation?

Check that the downloaded CP configuration matches the physical station address, baud rate, bus profile and expected DP slaves. Inspect Sub-D connector seating, shield bonding and termination, then use STEP 7 diagnostics to identify the first missing station.

What should I check when 6GK7342-5DA03-0XE0 is online but the CPU receives no DP process data?

Verify the configured logical addresses and the DP_SEND and DP_RECV calls, including enable conditions, data lengths and status words. Confirm that the CP is in RUN and the user data areas agree with the hardware configuration.

Can an older CP 342-5 be replaced by 6GK7342-5DA03-0XE0 without project changes?

Do not assume compatibility from the CP name alone. Compare the predecessor order number, module revision, supported functions and STEP 7 configuration, then compile and test every affected DP slave and communication connection.

How should bus parameters be changed safely when commissioning 6GK7342-5DA03-0XE0?

Use a communication path that will not be lost by the parameter change. Preserve the current project, update every affected station consistently and verify the DP segment before restoring outputs.
