2.5 Creating a PROFINET IO Configuration with STEP 7

The Simatic_Step7 directory on the DK-ERTEC 200 PN IO CD contains a finished STEP 7 project suitable for the

device application. It includes the following:

• Bus configuration with CPU319 IO controller and PNIO device

• Configuration of the inputs and outputs of the PNIO device

• STEP 7 program with alarm OBs for process alarm, diagnostic alarm (OB 82), and return of submodule

alarm.

• Variable table for online status display

We recommend that you use this example unchanged for the initial commissioning. For STEP 7, import the

Simatic_Step7\EB200_PN-IO_S7-319.zip project in STEP 7 SIMATIC Manager via the menu command

"FileÆRetrieve".

Then open HW Config in this project. This displays the following configuration:

1. Save and compile

2. Download the bus configuration

3. Device name EB200PNIO for device in this example

Figure 4: Configuring a PROFINET Device with EB 200 in HW CONFIG

The screen form shows the bus configuration, consisting of a CPU319-3 PN/DP as the IO controller and an

ERTEC 200 evaluation board as the IO device. The table shows the module configuration for the selected device.

In the example shown here, 2 modules (one 64-byte input module and one 64-byte output module) have been

inserted in slots 1 and 2. The I-address and O-address columns indicate where the I/O data in the process image

of the CPU 319 are stored for use in the STEP 7 program. For example, the data of the digital input module on

slot 1 are stored in the process image in input bytes EB256 to EB319.

Important note:

Of course, the modules in this example are only virtual, i.e., they do not exist physically on the ERTEC 200

evaluation module. In addition, the displayed order numbers were randomly defined and stored in the device

description file (GSD file).
