Technical support / Phase Lock Loop
« on: August 03, 2011, 09:36:02 AM »
What would be the easiest way to program a phase lock loop or what basic keywords would i use to get started. Should i try to take a loop and compare set frequency to incoming frequency and make the two match?

Technical support / FMD1616-10 Online Monitoring
« on: June 20, 2011, 09:53:01 AM »
I am having an issue with an FMD1616-10. I'm not sure why, but when I boot up the plc it will correctly show up the lights on the inputs, but the online monitoring will not correctly show the inputs.

To narrow down the problem I have tried several different things.

Upgraded to the newest software version and I am running the correct jre.

I checked to see if all grounds were connected.

Had the correct voltage on both power supplies.

Unplugged various things to make sure it wasn't something hooked up to the plc.

Loaded several different programs revisions.

Then I Loaded the same exact program to a F2424 on my bench setup and the problem was corrected. Then when I unplugged all connectors from the F2424 and replaced it with the FMD1616 and the problem was back.

This all leads me to a Problem with my FMD1616-10.
So what do I do next?
