A have made the modification in the program, but I do not know how to burn it into the EPROM. I use a Field PG, so hopefully I have all the needed hardware to do it. Please if somebody has a few minutes, write me step by step the method (erease, write, parameters, I don't know anything), so even I can follow it and learn it :) Great thanks: Coyote

But before that you need to erase the EPROM by using UV EPROM Eraser. Than select your program. Insert your EPROM in the specified location in the Field PG. Go to EPROM handling MENU. There you have to select "BLOW". ( As I dont have the software installed I cant tell you the exact thing, but I remember this is mostly correct). Than select your EPROM module by pressing F12, you will get an Window. Give the no of your module. Select "All" and than write the data to the EPROM. You can make a crosscheck by READ again from the EPROM but save it in a different path. Hope this will help you. Regards Rabindra

Since you have a Field PG you should have the Step 5 manual on it (as well as on the CD that came with your PG) and you will find EPROM handling quite well explained in it. Alternatively, search the Service & Suport web for the manual for your version of Step 5. Below is the link for the latest version (V7.2), chapter 18.2 is in the case the one you want to consult. SIMATIC STEP 5 V7.2manual I hope this helps

The power output of your UV lamp in Watt/cm² 2.) The Watt-seconds/cm²requiredfor erasing. Number 1is something you may know/get of the lamp, number 2 is specified by the EPROM manufacturer. Additional factors such as lamp age, cleanliness of the EPROM window (i.e sticker residue), previous erasing "history" etc. have an effect on the required erase time too. Sounds complicated, doesn't it?, so here's my advise: Erase for at least 30 minutes (this is also the minium timethat must be set for the offical Siemens S5 UV Eraser), but preferably erase for 1 hour (there is no such thing as "over-erasing", I've had S5 EPROM's under UV lamps "accidentally" overnight). Check out this FAQ too which deals with the subject of too short erasing time: After Deletion, EPROM-"blowing" is impossible I hope this helps

But fail to do so. First time I kept EPROM under UV lamp for 90 minutes. In my next attempt I spent a whole night (more than 9 hours) but still the program was existed in that... so, now I conclude that even the UV cant erase the existed program successfully. :/
