Direct Logic 05.... I'm struggling!

[iansmiler]

Hello all Hardware: DL05, Analog input card, 0 - 10VDC Ultrasonic sensor.

Outcome I want to achieve: upon activation of XO I want to take a snapshot of what the sensor is reading every let's say 20ms and move them into an array of data registers (How I wish I was doing this with logix5000 :/ ), X0 will stay active for no more than 2 seconds and so I do not need a big array.

Is there any easy way to achieve this?

Any help appreciated

I didn't know which analog input module you had, so I went with the four channel voltage unit. This program writes the raw value of channel 0 to 16 registers, V2500-V2507, and V2510-V2517 (it is octal addressing). It writes the value every 0.02 seconds and goes back to V2500 after writing to V2517. I haven't tested this but I think it should work.

iansmiler,

I wanted to give you an other way to do what you asked. I like kittydog42 I did not know which analog module, so I chose the F0-08ADH-2 8-Ch. Analog Voltage Input. This module uses two Vmems for each analog channel.

Copy and paste the text below into notepad, save it open a new instance of Direct Soft, click on file, import, program, to convert the text to a program.

Guys - thanks for both posts with a bit of copy and pasting I managed to achieve what I wanted - BIG HELP THANKYOU Anyways - The ultrasonic sensors were no good, the feedback wasn't quick enough. I have 2 laser sensors winging there way to me now - I will report back and post my final program when they arrive......
