Select the appropriate menu command (menu: PLC > Diagnostics/Settings >

...).

As of STEP 7 V5.3 Service Pack 2, the "Module Information" diagnostic function can also be used for DP slaves "behind" the IE/PB link; that is, for those devices that are not directly connected to the Ethernet.

4.4.3 Downloading to PROFINET IO Devices

Downloading to the CPU serving as IO controller for the first time in HW Config After you have configured the whole IO system, you now have to download this configuration to the CPU. In this way, the IP address is assigned to the CPU (or more exactly: the IO controller).

Before starting the download, you should perform a consistency check in order to have the configuration checked for addresses that have been used twice and names that are not unique.

Find out if the CPU to receive the download can be downloaded to for the first time via the PROFINET interface. If not, you will then have to first download the

hardware configuration via the MPI interface.

The following description of the procedure presumes that there is a connection existing between the programming device (PG) and the CPU via Ethernet.

1. Select the PLC > Download menu command.

2. Select the modules to be downloaded to.

3. If necessary, in the "Select Station Address" dialog box, click the "Display"

button to display the modules that are actually accessible (including the CPU to receive the download with its current IP address or its MAC address if an IP address is still not available).

4. In the accessible modules, select the CPU to receive the download .

This module is then displayed in the "Enter connection to target station" field.

5. Start the download by clicking the "OK" button.

During this process, the CPU (i.e. the IO controller) also gets its configured IP address assigned to it.

Downloading to the CPU serving as IO controller for the first time in the SIMATIC Manager or NetPro

As an alternative method, you can download to the station (with the CPU of the IO controller) in the SIMATIC Manager or NetPro (menu command: PLC >

Download).

If you trigger the download in the SIMATIC Manager, the configuration must have already been compiled (in HW Config or NetPro).

Configuring PROFINET IO Devices

Procedure

1. In HW Config or in NetPro, select the PLC > Ethernet > Assign Device Name menu command

2. In the "Assign Device Name" dialog box, go to the "Device Name" field and select a device. Then, in the "Available Devices" field, select the device to receive the selected device name.

3. To make the device easier to identify, click the "Flashing" button to cause a display LED in the selected device to flash.

4. Click the "Assign Name" button.

5. Repeat steps 2 through 4 until you have assigned a name to all the devices.

Starting the CPU

After the names are all assigned, you can put the CPU into RUN mode.

At startup, the CPU distributes the configuration information to the IO devices and then goes into cyclical operation.

4.4.4 Assigning Device Names via a Memory Card (MMC)

As of STEP 7 V5.3 SP2, you can also configure the device names of PROFINET IO devices offline.

To do this, you save a configured device name to an MMC and then insert the MMC into the appropriate IO device.

If a device becomes defective and an IO device has to be completely exchanged, the IO controller automatically assigns the parameters to the new device and configures it. With an MMC card, a device can be exchanged without using a programming device (PG).

Requirements

• The programming device (PG)/PC has a prommer for MMCs.

• The IO device must support the "Assign the device name via MMC" function.

• The station with its PROFINET IO system is configured.

Procedure

1. Insert the MMC in the prommer.

2. In HW Config or in NetPro, select the IO device to be assigned the device name via MMC.

3. Select the PLC > Save Device Name to Memory Card menu command.

4. If the MMC has other data on it, a message will inform you of this condition so that you can delete the MMC before saving the device name.

4.4.5 Changing the IP-Address or the Device Name During Operation

Assigning an IP address or device name for a single node

Before a new IP address or a device name can be assigned, the following conditions must be met:

There is no data being exchanged with the IO controller.

If the SIMATIC Manager or the list of accessible nodes is open, you can assign each PROFINET-device an/another IP address another device name. To do this, select the PLC > Assign Ethernet Address menu command.

Changing IP addresses from a central location

If you have to check or change the IP addressees for several IO devices, proceed as follows:

1. In HW Config, select the PROFINET IO system (the "railroad track") and then select Edit > PROFINET IO > PROFINET IO System > IP Addresses menu command. Alternative method: you can also find this function by selecting an IO system and then right-clicking to display the context menu.

2. The dialog box that is then displayed shows all the IO devices with their current device names and IP addresses. You can change all the IP addresses from this central location.

3. Download the changed IP addresses (menu command: PLC > Download to
