Timer TON convertion from ms to min

[Persephone]

Hi there i was wondering if we can change in the TON the ms to min.....

or how can i make a transformation... that shows up in c-more.

cuz I am grabbing the data of the timer to show up in the hmi but the values are over 2000, and i want them to be 2 cifres


please help,

PLC type?

No, you cannot change how the timer increments. But you can use math to solve your problem.

If your timer is timing in milliseconds, then simply use a DIV to divide the accumulated value (by 1,000 to see seconds or 60,000 to see minutes). Store the result in a tag and then you configure the C-more application to look at that tag to display your timer value.


EDIT: I said MUL before instead of the correct DIV

Assuming that the TON's accumulated milliseconds is a 32-bit integer, create a 32-bit integer tag in the C-More linked to it and scale the value in the numeric display. With that you can easily display the value in increments of tenths of a minute (six seconds). If you want the display to be in minutes and seconds you have to do a little more work which is probably easier done in the PLC than in the C-More.

For HMI's I never have the timer or counter directly read or written to,


I always MOV T.ACC to a DINT, to change it as you want simply DIV the.ACC but 60000 to a DINT or REAL - the REAL would show decimal places and can be truncated to 1 or 2 decimal places

Hi, remember as I_Automation stated, don't write directly to the timer. Also one can reverse the process and have a numerical keypad on the HMI that and an operator can enter a value say in minutes and the timer logic will get the preset in msec. Hope this helps.

Are you looking for minutes and seconds? Make new tags for the C-More to read in PLC for minute and second.

Seconds = (TON.acc DIV 1000) MOD 60
Minutes = ( (TON.acc DIV 1000) - Seconds) DIV 60
