Hi, I am trying to build a little control system for a washing system. It comprises of 2 tanks which both have 2 x 9kW heaters in so a potential of 36kW. However the generator to run this will only allow 2 heaters to be operated at any one time. I have 2 X 3 position selector switches on the control panel. They are labelled TANK1 and TANK 2 respectively. They have a mid OFF position then a HEATER 1 ON and BOTH HEATERS ON position. I need to be able to interlock the heaters and tanks somehow so that only 2 heaters can be selected ant any one time. Unfortunately the customer wants the option to have 1 heater on in each tank also which is the part I cannot get my head around at the moment being a newbie to ladder logic. Can anyone point me in the right direction please? I am also looking for a PLC programmer in the South of England if anyone knows of a good one? Thanks Duncan

Hi all, I wonder if anyone can point me in the right direction. I have got a project on an old PLC where I need o make a change in the software. I have an old laptop with LSS on and I also have a newer laptop with syswin. Is ther a way to upload from the CQM via syswin to include the data memory etc and if so do I need to download the data memory seperately as per LSS? Any help would be greatly appreciated Many thanks DJDUNKY

Yes I suppose so....i don't know if this will work!!!

thanks for your help gtsuport. I have used the 'Convert from' feature within Syswin to convert the PCG2000.dat file from LSS into the syswin format. This does not seem to include the data memory or maybe I am not looking in the right place. Can anyone advise?

Thanks Bob, I have only ever used syswin once and from memory I couldn't work out how to upload the data memory, does anyone know?
