Hello,

but I want to increase the value for example every hour. The time have to be variable so I need a calcout timer to count for example every 10 second from 0 to ‎50 and then to increase the value step by step. My problem is how to realise  this with two records. One have to increase +1, then go to the timer record and wait for example one hour set value and again: increase +1, then process timer or counter for slowly periodic scan, set value. 

Thanks.

Hello,

I want to set a value like 200 ampere and increase the current value slowly but how? 

I have a timer-record with a PROC field with the option "transition to zero". A second record increase the value every time. Is it possible to create records like this: 

• Calcout1 timer: scan every second from 1 to 10

• -» then process Calcout2 (via PROC field, without SCAN field) from 1 to 3

• Calcout2 have to wait, process Calcout1 again...

In the ao record that is setting your value, set the field SCAN to "1 second" (or how often you want to "slowly" update) and the field OROC to the step size that you want to the value to change every time (e.g. 0.1).
No other records needed.

Now, when you write a value like 200 to that record, the output will step up by 0.1 every second. (Or whatever step size and update rate you configured.)

Hope this helps,
