Calculating the MAC address from the serial number

Deutschmann Automation GmbH & Co. KG

13 Calculating the MAC address from the serial number

Basically you can see the MAC-address from the IC's status signal (see chapter 7.2 'The

configuration mode').

With the following calculation formula you can calculate the MAC-address from the serial number

(SN), that is attached to the IC:

MAC = (SN - 28950000) + 86184558592

Since the MAC is issued as a 6-digit hex-number, anyways (xx-xx-xx-xx-xx-xx), the following cal-

culation is probably better:

Issue: MAC1-MAC2-MAC3-MAC4-MAC5-MAC6

Calculation:

MAC1 = 00

MAC2 = 14

MAC3 = 11

MAC4 = (SN - 28950000) / 65536

MAC5 = ((SN - 28950000) / 256) mod 256

MAC6 = (SN - 28950000) mod 256

Consequently the device with the SN 32180349 has the MAC 00-14-11-31-4A-8D
