Running MOVITOOLS via PROFIBUS ®  MotionStudio

7.1 Hardware and software requirements

Hardware: Siemens CP5512 (PCMCIA) or CP5611 (PCI) PROFIBUS master card.

software

STEP7 V5.3 SP3 or higher (optional)

SIMATIC NET Softnet DP Driver (V6.0+)

MOVITOOLS ®  MotionStudio V5.20+

7.2 Configuration steps

Install drivers and software.

Select the CP card in "Set PG/PC Interface" and set the parameters (baud rate, station address, uncheck "Unique Master Station").

Diagnostic test: Click "Test" to confirm OK, and click "Read" to list all devices on the bus.

Start MOVITOOLS ®  MotionStudio， Open the SEW communication server.

Add PROFIBUS communication channel by drag and drop, configure as C2 master station.

Perform unit scan (F5), locate online devices, switch to online mode to perform parameter reading and writing, oscilloscope monitoring, etc.

7.3 Common Problems

The bus terminal resistance is not set correctly.

The PC address conflicts with an existing master station.

Checking 'PG/PC is the only master on the bus' prevents coexistence with C1 master station.

The baud rate does not match the actual bus rate.

Fault diagnosis

8.1 Diagnostic Process

Problem 1: The frequency converter is not working on PROFIBUS (BUS FAULT is on)

Check cable connections and terminal resistance.

Is the checkpoint address within the range of 1-125.

Check if the GSD file is correct and if the configuration has been downloaded.

Check if the main station is running.

Problem 2: The frequency converter can communicate but cannot be controlled

Check if P100/P101 is set to FILDBUS (or SBus).

Use P094~P097 to check if the process data is received correctly.

Check if the terminal enable signal has been provided.

Check if SFC14/15 is used in the program to ensure data consistency.

8.2 Fault code list (optional)

Possible causes and countermeasures for fault code names

28 fieldbus timeout, master-slave communication interruption check, master station communication, extend monitoring time

37 Watchdog Error System Software Error Contact SEW Service

45 initialization error reset after self check failure, power off and restart. If it repeatedly occurs, send it for repair

111 system error (gateway): The device on SBus cannot be addressed or the DFP itself is faulty. Check the SBus wiring and terminal resistance, and power on again
