The minor revision returned will be calculated from the formula:
#11.29 Mod 100 + 1.
Where “ #11.29 Mod 100” refers to the fractional value of Pr 11.29 , (the value after the
decimal point).
e.g. For a value of “1.09” in Pr
11.29 , the minor revision returned is 10.
Bits b0 to b6 are used to inform the configuration tool that the advanced EDS file is not
enabled and each bit will be set to 1.
If an advanced EDS file is used then the revision number is calculated as shown below.
Minor revision
The minor revision returned will be calculated from the formula:
#11.29 Mod 100 + 1.
Where “ #11.29 Mod 100” refers to the fractional value of Pr 11.29 , (the value after
the decimal point).
e.g. For a value of “1.09” in Pr
11.29 , the minor revision returned is 10.
Sub-version
The sub-version returned will be calculated from the formula:
#11.34 + 1.
e.g. For a value of “1” in Pr 11.34 , the sub-version returned is 2.
Serial Number
Returns the least 3 significant bytes of the SM-Ethernet MAC address. The MAC
address is set during production, and cannot be changed. This value is also displayed in
Pr
MM.35 .

This can be used to find the complete MAC address of the module by combining the
numbers with 00:0D:1E:xx.xx.xx. Where xx.xx.xx. is a value in Pr
MM.35 converted to
base 16 (HEX). e.g. If Pr MM.35 contains the value of 1193046, this would give the
complete MAC address of 00 0D 1E 12 34 56.
