Calculate Timer Preset

I am using a c-more panel to input a timer preset of 1.5 minutes. I have been able to load the value into V memory of a DL06, but can't calculate the seconds required for the timer preset using LD, MUL, OUT to a TMRA. Sounds simple enough, just multiply by 60, right? Also, shouldn't putting a SP1 relay in front of this rung make it execute every scan? I'd really appreciate any help with this as I'm running out of time. Thanks

Check your tag value in the C-more panel. It should be set to BCD INT 16 in order to function with timers.
600 would be the correct number if you are using a TMR or TMRA. If you are using a TMRF or TMRAF then the value would be 6000.
The easy way to do this is to use the scaling feature found under the "Option " tab in the numeric entry object. In the PLC side use 0 and 9999. In the display value use 0 and 16.665. This eliminates PLC coding completely.

Thanks for the response.
I am using a numerical entry object with up-down arrows to preset the timers. I don't see where there is an option to set the tag value to BCD INT 16. The only options available are Unsigned Decimal,Octal,&Hex.

Create a new tag with the same address. Before pressing "Ok " you will see a drop down with a list of available data types. One of these will be BCD INT 16. Once you have used the tag, you can no longer change the data type, just how it is displayed.
