In order to test a hardware converter that I have designed to convert +-5V input to 2.5 V input as the ADC 11/12 uses, I have found out that the Picolog program doesn't set the samplerate for the ADC11/12 correctly!
Here is what I do:
I use a signalgenerator as input to the ADC11/12, set at 10HZ, +-5V(remember I use my own hardware converter).
Then I set the Picolog program to sample at 1ms intervals for 500 samples, which gives me 5 periods over 500ms of signal from my signalgenerator.
Then I set the Picolog program to sample at 10ms intervals for 50 samples, which gives me 0.5 periods over 500ms NOT 5 periods!
Then I set the Picolog program to sample at 5ms intervals for 100 samples, which gives me 1 period over 500ms NOT 5 periods!
I used Picolog release:5.09.4
WHAT is going on here??
