Setup Guide - Profibus communication - AC141x with Step 7 V5.5

Contents:

1. Connect the Profibus Unit

2. Create a Project and set the PG/PC Interface

3. Configure the Hardware

4. Configure the Profibus Gateway

5. Transfer the Project

6. Monitor the Inputs and Outputs



1. Connect the Profibus Unit

Siemens PLC with Profibus Interface

ifm AS-i / PB Gateway AC141xLaptop / PC




Create project Start Simatic Manager with

icon from desktop

Use an appropriate name for the project

Confirm with OK




Set the PG/PC interface Set the PG/PC-Interface using

„Options -> Set PG/PC Interface“.

Choose the PC from the list of Ethernet interfaces.

Confirm with OK

Confirm with OK




Add the Simatic Station Add the PLC to the project : „Insert -> Station -> Simatic 300 Station or

Simatic 400 Station“

Open the Hardware configuration




Add Rail Add the Rack Rail by using „drag and drop“ on the respective icon from the

catalogue.




Add CPU Add the CPU by using „drag and drop“ to the respective slot from the catalogue.




Set the Ethernet interface Enter the IP address for the

Ethernet interface of the PLC

Click „New…“ to add the ethernet connection

Enter an appropriate name for the Ethernet connection




Set Ethernet interface The Ethernet interface „Ethernet1“

is now added. Close the configuration session with OK.

This interface will be used to upload and download the PLC configuration and program




Install GSD File The „Generic Station

Description “ File (GSD File) is required in order to integrate the Profibus gateway into the hardware configuration. When using the Profibus gateway with the Step 7 system for the first time, the GSD File is to be installed via „Options -> Install GSD File….“

Choose the GSD File with „Browse…“

Start the installation




Add the Profibus path – right click on the MPI/DP interface to create the Profibus connection

Add the Profibus gateway Choose the Profibus gateway from the catalogue using the following steps: „Profibus

DP -> Additional Field Devices -> Gateway -> ifm electronic gmbh -> AS-Interface -> AC1411/12-PB V2.0 and add it to Profibus network.




Description of the Slots Slots 1 - 4: digital IO signals M1/M2 (address 0-63) Slots 5 - 6: analogue inputs M1/M2 (address 256 – 263) Slots 7 - 8: analogue outputs M1/M2 (address 256 – 263)




Description of Slots Slots 1 - 4: digital IO signals




Description of Slots Slots 5 - 6: analogue inputs/outputs, Data mapping and corresponding parameter setting:

analogue channels per input / output slave" = 1 analogue channels per input / output slave" = 2 „analogue channels per input / output slave" = 4 is not suitable for this

representations since it can be defined by the user.

. Complete table for data mapping is given in the Device Manual



5. Transfer the Project Save the configuration using Ctrl + S or „Station -> Save and Compile“

Load the configuration to PLC using Ctrl + L or „PLC -> Download“

If the configuration is correct, the bus error LEDs (BF 1 and BF 2) are out and the system error LED (SF) of the CPU is green.




Create a Variable Table (VAT) in Step7 Insert -> Range of Variables…

IW for Input Words or PIW for Periphery Input Words IB für Input Bytes or PIB for Periphery Input Bytes Ix.y for Input-Bits, for example . I64.1 for bit 1 in input byte 64 -> Read inputs via monitor variable (glasses)

QW for Output Word or PQW for Periphery Output Word QB for Output Byte or PQB for Periphery Output Byte Qx.y for Output Bit, for example Q64.1 for bit 1 in output byte 64 -> Outputs can be set via Variable Control



6. Monitor the Inputs and Outputs Add variable table by right clicking left window, Insert New Object –> Variable table






6. Monitor the Inputs and Outputs Open VAT table by clicking on VAT1 To add variables, Go to Insert Range of Variable



6. Monitor the Inputs and Outputs To Monitor values, Variable Monitor
