Any help would be appreciated. Attachment Sistema_riego_movil-v2.zip (28 Downloads)

Because (as shown in the appendix) the value 0 can be seen in the opened parameter field? This has no meaning when watching online. The values displayed in this field are only valid for offline viewing and for simulation. Attachment Unknown.PNG (53 Downloads)

I tested in the field and the B012 Cnt resets at 10 pulses in I3 as it should be. I thought I didn't work because of the online mode. Thank you!
