1 Slave Radio(6105-WA-PDPS), 3 Master Radios(6104-WA-PDPM)

Here is the current configuration of my network:

-Siemens PLC is connected with the 6105-WA-PDPS.
-The 6105-WA-PDPS is talking WIRELESSLY with three 6104-WA-PDPMs.
-Each 6104-WA-PDPM is connected with a drive.

Right now, this set up works great. Communication is running fine.
My question is:
-Is there any way that the PLC knows when one of the masters radio lost connection with the slave radio? or is the Slave radio knows when one of the masters radio not communicating anymore?

Thanks
