Hi Freshsurfer, you can download a 60 day evaluation of Step7 Microwin at http://www.ad.siemens.de/s7-200/html_76/evaluation_microwin.htm You'll need the PC/PPI cable though. What do you use to connect to the S7-300? If you have a CP5511 card you can use this to connect to the S7-200 also...

Tom, You need a program to delete all evidence of the trial version on your computer, e.g. AShampoo. When you uninstall a program with this it gets rid of all evidence of the trial on your pc and starts again at 60 days. MartinBEng.

Try the Siemens Energy and automation website http://www.sea.siemens.com/sales/default.html You'll have to contact your local distributor as listed there. MartinBEng

Hello Benga, I ha exactly the same problem as you. There were not enough free resources when I used the "fix" .exe from Siemens. I tried several options but had no luck. In the end I re-installed windows, and before reinstalling any other programs, drivers etc I installed Step7 and...

ipupkin, I tried several times to create a hardware profile but it kept freezing the PC. After all my frustration I decided to format the drive and re-install windows. I did it and it worked.....at last, the CP5511 card seemed to find it's place. It was big hassle but saved me $1100 on a new...

ipupkin, My CP5511 is at IRQ 07, this is not creating a conflict, but when I try to set the memory range a conflict is created. When I try to set the memory range manually the first of the 2 settings has no resources available, all the resources are being used up by the cardbus controller. ...

Finally, the problem is that there is not enough free memory in the d-segment section. The entry D000-DFFF doesn't seem to exist (under device manager>simatic net>CP5511>properties>resources>memory)????? MartinBEng

Hi In97, Are you sure, because I got a quote for a CP5512 at $1100 US!! MartinBEng

Zenith, When you get to, say, 29 days of the evaluation uninstall it and install it again that way it won't close the evaluation for further use. MartinBEng.

When trying the solution listed on Siemens webpages: http://www4.ad.siemens.de/WW/view/en/6721667 and http://www4.ad.siemens.de/WW/view/en/9853739 I had no success as there is conflicts with the Interrupt Request (IRQ) memory resources in device manager. When I changed the memory...

Hi Jacekd, My laptop runs XP home. I know it's not approved for Step7 but friends of mine have successfully loaded and are using it with XP home edition. My problem is with conflicting memory allocation for the CP5511. I found a possible resolution at Siemens online at...

Dear ipupkin, Yes, I already checked the connection in the "set PG/PC interface" section but when applying the test in the diagnostics option it returns "hardware not found". I'll try the ad.support. Thanks, MartinBEng

Dear all, I recently upgraded from Siemens Step7 v5.1 to v5.2. When I tried to reconnect to the PLC I received and error saying that "the configured hardware interface is already being used by another programming package" I am using the CP5511 card and MPI cable which worked fine...

Thanks dgallagher Our site doesn't have a central control system, but 3 major areas, one of which is totally controlled by PLC's. I'll look into Wonderware. MartinBEng

Hi GusD, I maybe didn't phrase my question correctly. I'm looking for software that can monitor all equipment in my factory, I will provide a seperate server for the database. I'm working in Haiti (carribean). Thanks MartinBEng

Hello all, I am looking for information on companies that offer server based site machinery monitoring, from PLC's to power meters, compressors, vacumns etc. Thanks MartinBEng

Thanks Daviango, We have a whole series of IQ 200 meters and several IQ 6600 series analysers. Siemens PLCs control our plant. Can automation solutions communicate to profibus controlled devices? MartinBEng

I am using a Crompton Synchrocheck relay 244-14hg to synchronise 2-3 generators in my factory. The relay blew some time ago and was replaced, it has blown again. I believe transients may be causing the relay to be damaged. Does anybody know of suitable voltage suppression units or any other...
