Hi,

I would like to know if I understood the Data Log function. A very simple situation is showed attached (I used a timing diagram to show who and when orders each log):

There are two buttons to start and stop a container cooling machine. An exclusive temperature sensor monitoring the container temperature. A Data Log added in the program was set to log I1 to I8, M1 to M8 and the analog amplifier (that convert analog signal range to real temperature). So I can say:

For digital signals: all ascending or descending edges of I1, I2 and M1 will be recorded.

For analog signal: it will be recorded with their actual value only at the same time of each ascending or descending edges of I1, I2 and M1. Also when the Data Log En is enabled, a log of analog amplifier is recorded.

Am I right?

I am using Logo! 8. Suppose that pulses time betweem I1 and I2 don´t occurs less then ten minutes.

Tank you for reply.

So I can say that one data line will be loged for each one positive edge in the Data Log function?

I defined logging data for: (I1 to I8) =  1 byte,  (Q1 to Q8)  = 1 byte,   (Analog parameter) = 1 byte

Supppose switching En of Data Log with 500 ms in state 1 and 500 ms in state 0.

Without a SD card,  like about 30 lines in 30 seconds will be recorded. The new one's wil not be recorded until a upload.

Is that right?

 Yes.
