[Retained variables Vision V130]

Hi all!

Can I use MI datas as retain? I'm using some variables, which I can change by the HMI.

But if I turn off the PLC, the data will be reset to the value specified in the program.

How can I solve this?

Thanks!

At the bottom of the picture you can see the variables, I can use them as well.
You can't see them in just one hardware configuration.

Ok.

Thanks!

I didn't know it was a mistake. Actually, I had no other problem.

I tried on several computers, the same. Windows 7 64bit OS. The last beta version is installed.

Hi!
Why can't I see the inputs?

 

Thanks!

I'm not sure I understand exactly what you're trying to do, but if you want to alternate engines every 2 hours of operation, I would assign a coil to determine currently active engine (0=Engine 1, 1=Engine 2), then toggle the coil triggered by your accumulating register. Place the inverted contact for that coil in series with MB0 and direct contact in series with MB1.

Thanks!

Can you upload your program with what you've done so far?  Then we can have a look.

Hi!
I would like to ask for help.
I have 2pcs of vacuum pumps, I want to switch to operating hours, which one to go. Switching should only take place in a stationary position.
I have written 2 hours of operation time counter.
There are two outputs MB0: M101 engine start, MB1: M102 engine start.
I have outputs for both operating hours. If set to <= current operating hours, MB2 and MB3 outputs are active (SET).
How can I do my logic simply?

Thanks!
