The actual article was in new scientist (7th March Edition) on pg 20 written by David Robson

Off topic here.. Was just reading an article on solar cells and about quantum dots, Making the solar cells much more efficient. Are u involved with this kinda thing?

What does everyone use to backup there scada clients? Currently using acronis but seems to take forever..

Absolute zero and u have free energy ;)

Who u logged is as on the 2k machine?

In your PLC use the service request #7 for reading the date/time of the PLC. The service request write the date/time into 5 or 6 word. In your Cimplicity project, create points to read the date/time words. Create a periodic Event launching a script. In this script use the Date function to set the PC date/time. Thats what i found from google, dont know if its any help :)

How come you did your NVQ 3 in mech maintenance? As i see you have done ONC in electrical, Are you multiskilled? I did HNC after ONC and really enjoyed it, if you want to do it defiantly do it!!

Would a ps2pdf convertor do the trick? If so check this out http://pages.cs.wisc.edu/~ghost/doc/gnu/5.50/Ps2pdf.htm Also is it a one off thing?

Going to be giving this a look in the next few minutes

Here is what the question was based on; A relay PLC switch has an inductance of 2H and resistance of 4Ohms. It has a current of 0.5A, when switched off Determine the time for the relay to drop out when the drop out current is 0.1A I get something like 804.72ms

Did actually enjoy reading that, nice post

Thanks very much guys

Thanks for the info guys. A friend PM'd me this a few minutes ago too (just to throw it in) James says: if i remember correctly... and dont quote me on this... but isn't it to do with spikes on a current signal
