7SJ621 Motor Protection--RTD-Box Measured values??

[86ed]

Is it possible to output the real time measured temp values from an RTD-Box (port C RS485) out through the System Interface(port B IEC61850)? I have looked through the DIGSI 4 Marshalling Information Groups and tried to create a CFC but was unable to find any information types associated with the 'winding' temp--MV or VI.

Thanks in advance.
