Step 3: Configuring the properties of the CP as PROFINET IO device

Continue configuration in HW Config as follows:

1. Open the properties dialog of the PROFINET IO device that you inserted in the

PROFINET IO system.

2. In the “General” tab, assign the same device name that you selected in Section

6.3.1.

Figure 6-5 Properties Dialog of the Device: Assigning the Device Name

3. Deselect the “Assign IP address by IO controller” option.

This step is a recommendation!

By deactivating this option, the IP address you assigned when you installed the

CP in the SIMATIC 300 station (see Section 6.3.1) comes into effect on the

PROFINET IO device. Otherwise the IP address you selected there will be

overwritten by an IP address assigned by the PROFINET IO controller. If it is

overwritten, any configured connections (S7, ISO-on-TCP, TCP) will no longer

be established.
