Siemens Port Configuration Tool

Several industrial products contain an out of bounds read vulnerability that could allow an attacker to cause a Blue Screen of Death (BSOD) crash of the underlying Windows kernel, leading to denial of service condition.
Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends countermeasures for products where fixes are not, or not yet available.
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: -guidelines-industrial-security), and to follow the recommendations in the product manuals.Additional information on Industrial Security by Siemens can be found at:

VULNERABILITY DESCRIPTION Un-/Collapse All This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.
Another option if you are using a s7300 PLC is to use an Ethernet/profinet module such as the 343-1 lean module. This fits on to the rack and gives you Ethernet connections to the PLC and direct addressing for your ignition program.
I am trying to using the Hilscher MPI Converter to connect to a Siemens S7 315-2dp and it doesnt seem to be working. I was expecting it to work straight away but i think i need to change the settings in the driver.
I finally managed to solve it with a firmware update on the hilscher unit, i was using an old NL-150 unit that i normally use for programming siemens PLC and the firmware was from v2.00 and way back from 2009. The minute i updated the firmware it connected and started working. Apparently V2.00 only supports PLC programming ???
Its relatively simple to update / identify the firmware. You need to have the latest version of the S7 IBHnet configuration tool, i think you are already using this for configuring the unit for programming.
Once connected to the configuration tool, it will show the current version and allow to update the firmware.
You cannot use it for programming and connectivity to ignition at the same time, also make sure the rack /slot parameters are correct. If you need screenshots of the steps let me know, i will be happy to help.
I got the latest IBHnet config tool, updated the firmware (was on 2.00) and it just worked then with no further changes. Thanks for the tips.
Does this mean I need to disconnect Ignition if I need to make program changes ?
Click on the Master block and drag it to your network and then assign it to the PLC. Select the IO link Master to open it in the device overview. Once again, using the hardware catalog side panel, select the port size definition. Under sub modules are the port configuration options where the inputs and outputs for each port can be assigned.
This video will demonstrate changing the IP address and ProfiNET device name of IO link masters using the TIA portal software. In the TIA portal software, go to the Portal view and select online access in the left hand panel.
Make the required changes and click the button to commit the change again under functions. Select Assign name. Adjust the device name and click the assign name button on the left hand side of the screen.
