thanks for your quick reply Paul it was very helpful lesliemcg

Hi all is there a package available out there to be able to get data from a S7-300 PLC using visual basic.net I would like to use this for a display only to show a machine performance on a stand alone application i.e. machine speed, thermocouple temps etc. I am not looking for writing values...

Thanks for the help guys I now have the program working the problem was in the temp tags # not latching due to memory (thanks jacekd) and when I used the M0.0 tags instead I didnt realise they shared the same address as MW0 S7 is so diffrent from VERSAPRO (GE-FANUC) so thanks for your help...

no problem paul, it does look like a double coil error so I tried using the same logic with internal flags (m0.0 etc)instead of #temp ones I am not using set/rest on the outputs/flags just a simple latch circuit. your right, it circuit worked until I expanded it with more logic only to get...

Hi guys new project requires S7-300 plc have got a 313-2DP and am having problems with FC blocks. simple logic isnt working like there is a conflict or something. no errors are shown in simatic manager but a coil isnt latched when its supposed to???? in say motor start stop circuit. I find its...

hi all, am i right that the formula to calculate torque is kw * 9550/rpm = Nm does this include ac and dc? thanks in advance lesliemcg

yes jacek, it really is a fast cylinder and high speed valve the cylinder slices through a hose and gets out of the way for the next one works well though leslie

Hi all, new to profibus i have a S7-300 (313C-2DP) and will have profibus in the system 6 drives and 10 pneumatic valves will be controlled on this bus one cylinder valve is very fast acting (12ms). will the profibus be able to switch on/off at this rate or will i have to hard wire to this valve...

thanks for your input tomatge a good point, i already have GE-FANUC cimplicity 50 point in the workplace but to network it around the factory i had to use DDE and export to excell for the tags to be seen by other PC users. i was just hoping for another system to do this by myself cheers lesliemcg

thanks for your reply jacekd, i'm still putting the project together so when i know the exact spec, i'll let you know the hardware thanks again lesliemcg

i think we got off in the wrong foot xnuke free labor would always be welcome but the main point i am making is that some companies do offer great tech support to get you started and up and running(what better way is there to sell a product) with the support and some homework you can set up a...

i think you are right thryll. everyone starts somewhere. i would recommend contacting the manufactures of the controls you are thinking of using. you will probally find they also offer a system which you could put together yourself (with tech support) it worked for me, my first scada, using...

HI ALL, HAS ANYONE EVER HAD ANY LUCK TO SET UP COMMS FOR VISUAL BASIC .NET AND GE FANUC PLC'S OR SIEMENS 300. I AM HOPING TO SET UP A PAGE WITH VB TO SEE REGISTER VALUES ETC BUT HAVENT A SCOOBIE HOW TO GET HANDSHAKING ANY IDEAS THANKS

thanks for your help plcsavvy although i'm pretty mad to find this out, i would have expected a major player in the automation sector to have this as standard especially with the cost involved to purchase the hardware (will know for future reference though) cheers lesliemcg

hi all, I am writing for any help for reading the clock in a 10" Quickpanel (GE FANUC)part number (IC753QSL001). I am using Quick designer software to program the panel. I wish to write the Quickpanel clock to the PLC (GE FANUC 90-30) using CPU 350 I cant find the option which configures a...

another manufacturer is ge fanuc 90-30 series this offers true on line editing while the plc is in run i have often changed variables while our machines are in production (even pid motor control) software i use is versapro (version 2.3) and have no problems only the hardware config cannot be...
