I found a thread for this topic below. The upshot was it cost 1100 Euros for the below service


We managed to find the PASSWORD for the PLC by purchasing the
services of Andi Rothenbacher in Germany

S.Rothenbacher GmbH
Benzstr.6 89079 Ulm
tel: 0731 45020
fax: 0731 46055

Andi was able to find the PASSWORD from a copy of the files
stored on the Micro Memory Card (MMC)
