How to configure SIMATIC STEP7 V5.5 to read cyclic data from

MultiRanger/HydroRanger 200 HMI over SmartLinx PROFIBUS

DPV1

Objective: To use Siemens SIMATC S7300 PLC to read data from MultiRanger/HydroRanger 200 HMI through

SmartLinx PROFIBUS DPV1 communication module.

Equipment Description MLFB Part Number

SIMATIC S7300 S7-315 PLC 6ES7 315-2AG10-0AB0

SIMATIC Step7 V5.5 SP4

SmartLinx PROFIBUS DPV1 module A5E35778741

MultiRanger or HydroRanger 200 HMI

Code example for the S7300 Step7 V5.5 SP4

While every effort was made to verify the following information, no warranty of accuracy or usability is expressed or implied.

Overview

This application guide is an addition to the operating instructions for the MultiRanger/HydroRanger 200 HMI. It focuses on the

configuration of SIMATC S7300 PLC to read the cyclic data from MultiRanger/HydroRanger 200 HMI over PROFIBUS DPV1.

During the reading process, the PLC will cyclically exchange data with the PROFIBUS slave and present the process data to the

user.

Hardware set-up

Open the MultiRanger/HydroRanger 200 HMI lid. 1.

Mount the SmartLinx module into the socket and fix it in place with the two fixing screws (included). 2.

Once in the hardware configuration screen, select the S7300 rack by clicking on the RACK-300 folder in the catalogue tree on 6.

the right side of the screen. Now click on the Rail and drag it over to the rack in the main window.

Then from the catalogue tree, select the S7300 CPU that you are currently using. In the example below, we are using the S7-7.

315 2 DP CPU.

Drag the CPU over to the rack in the main screen. You will then see the window shown below. 8.

In the pop-up window, click on the Parameters tab and enter the master address. Then click on New to add the PROFIBUS 9.

network. A new window will appear.

In the new window, enter information into the fields as shown below. Click OK to go back to the main screen. The PROFIBUS 10.

network has been added to the CPU.

The main hardware window should now look like this:

From the catalogue tree, select the PROFIBUS DPV1 card by clicking through PROFIBUS DP, Additional Field Devices, 11.

General, Anybus DPV1 IM.

Drag the Anybus device onto the PROFIBUS network shown below. A new window will appear. 12.

In the new window, enter the slave address for the MultiRanger/HydroRanger 200 HMI and click OK. 13.

Note: The address here should match the address of the rotary switches on the SmartLinx card.

Now, in the catalogue tree, highlight the Anybus device you have just added. Drag the relevant modules from the catalogue 14.

into the slots to make up 19 Words of input.

From the Station menu, select Save and Compile. 15.

From the PLC menu, select Download to download the configuration to the PLC. 16.

Close the hardware configuration window. 17.

Select Blocks from the main project window. 18.

Right click on the Blocks folder, select Insert New Object and then choose Variable Table. 19.

Enter a name for the VAT table or leave as the default VAT1. 20.
