Thanks to both of you, I will utilise what you have told me in the future

Thanks very much for your reply Micheal. I'm not in work till Monday now but I'll have a look and see if your method is better than what I came up with. I did get it working in the end of a fashion but it was probably over complicated due to lack of experience. I think I did some thing similar to what you suggested and then used a counter in loop to pulse every #600 on the back of TIML (I.e one minute). These one minute counts are then fed into a subtraction instruction which subtracts one from the set time (I.e 15 minutes) which the NS now looks at and displays minutes remaining counting down 😀 which is more user friendly than 9000 seconds. Although it probably would have been more fun leaving it like that and watching the factory floor staff with calculators out and scratching heads.

I should just like to make note of an alteration, i was using MOV instruction which was fine when i have been bench testing using smaller #numbers for my timer. I am now using MOVL to accomodate for the extra numbers required for the 30, 45 and 60 minute timer. i.e MOV is restricted to 4 digits where as MOVL can have upto 8. Slaps head, silly boy!

Hi everyone, could do with some assistants, getting a little confused :( I have a cj1m cpu11 PLC and a NS8 touch screen connected together and working a treat :) From the NS8 i have 4 individual on/off momentary buttons. They are set to trigger 2000.05 through to 2000.08. pb1- 2000.05 triggers a MOV function within the PLC, moving #9000 (15 minute) time into 2200 which is the SV word on a TIML instruction pb2- 2000.06 does the above #18000 (30 minute time) pb3- 2000.07 does the above #27000 (45 minute time) pb4- 2000.08 does the above #36000 (60 minute time) When each button is pushed they MOV data to the same TIML instruction depending on which button is pushed. They also input to a SET instruction 2100.05 whos funtion is to start the timer counting. The Completion Flag of the TIML is 2300 which RSET 2100.05 The PV word of the TIML is 2400. Now ive got that info laid down, my question is this, i want to let the user know what the current time is left on the timer till completion on my NS touch screen. Ive generated a 'Numeral Display & Input' box and linked it to 2400 (PV word) My problem is that the NS instead of reading #.... it seems to be counting down in HEX, i think. How can i alter this. Please help, its bursting my feeble little mind. Kind Regards Jonny Cooke
