Control LED on CPU

Hi all,
On the 2152 CPU are different LED`s located. (BF-C / RUN, fail etc. etc.)
The lowest one (left) has no meaning as far as I know.

                                            Is it possible to control this LED from the IEC program?  
                                            I`m building an MQTT client, and want to light up this LED when server connection is established.

No, this is not possible, sorry.
