Thanks!

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.

Can i open my beta project in this version?

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!

Thanks!

Dear Joe T. Thanks for the help! vacuum.vlp

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? V130 PLC Thanks!
