I working on a system controlling 10 small VSDs powering water pumps in a water feature. I am using a V350 with 10 Analog outputs to control the VSDs. Could any one recommend how I could achieve varying outputs so as to achieve several pump sequences.

The plant i am working on has a V570 unit installed, the company that installed the unit no longer exists. They did not burn any download, is there any way the view/change the programme.

Thank you for your reply, what i'm trying to avoid is the operator setting the time to zero when using the keypad entry, can this be achieved, by say having a minimun setting?

Thanks Joe, Tried a few of my own in paint, will have to play around with the pixels etc a bit, to achieve good images. Rich.

Hi, I'm have started using unitronics plcs, and am relatively new to plc programming. On an application i'm currently working on, i am using a number of run/pause timer applications to run a number of pump sets. Is there a way of setting a minimun time setting for a timer so as to avoid for example two timers (run and pause timers) being set at zero, thus causing rapid switching of outputs. Most of the applications in the project involve the run sequences from 3 to 20 minutes and the pause to be2 to 10 minutes, so if i could set both timers for a minimun of say 1 minute. I'm am using a V350-35-T2 unit, the operaters change the timers settings via the touch screen keypad. Regards, Rich.

Hi all, Just started usuing Unitronics PLC/HMI, inparticular the Vision 350. Is there an extended image labrary available, or can i get some info on importing my own images from other software, for example microsoft paint. Regards, Rich.
