[Time calculations]

Hello,

Is it possible to directly input time (HH:MM) in the HMI (keyboard touchscreen) and do calculations with this input?

Example

INPUT:

input first start time of a cyclus : 08:00 (HH:MM)

input last start time of a cyclus: 10:00

input number of starts: 3

This number says that there will be 3 starts of a cyclus. This starts must be equally divided over the time between the first and last start.

OUTPUT:

first start at 08:00

second start at 09:00

last start at 10:00

 

In this program we need to calculate the difference between first start time and last start time: 10:00 - 8:00 = 2:00

In this program we need to define the period between the start moments= 2:00/(3-1)=1:00

 

 

[counter based on clock versus timers]

Hello,

 

I tested the counter and it works perfect.

Just one remark : the SB3 should be used with a positive pulse coil or changed by SB13.

This looks perfect for our project. Thank you very much.

The sb3 bit is synchronised with the clock speed I suppose, so we don't have to be afraid of having a time fault after some time period?

[counter based on clock versus timers]

Is it possible in Visilogic to make a counter based on the clock speed? An other possibility is using the standard timers, but we need the possibility tot start a process, and keep tracking (and showing) the time that the process has been running (without time limitation).
