Support Questions / Make Custom Components

« on: July 25, 2022, 06:30:23 AM »

Hi, How do I go about make a custom component, i'd like to make a simple PID pump graphic, turns green when running, grey when idle and a red circle around it when faulted. I thought I might be able to modify the three colour pilot light, except can't figure out how to get to the graphics side of it. example image attached.

Thanks

Thanks Archie, the new driver is working like a charm. I will definitely consider using advanced hmi on some of our smaller projects.

Thanks for the prompt support. Yes, I did see the CIP Ethernet/IP mentioned in the manual and tried the CLX driver before I moved to the modbus TCP driver. The CLX driver return the error, Unable to determine processor type. I then did some digging and found a tech note about the the ethernet/ip on the 850, it mentioned not being able to interface with panel view screens, through ethernet ip and that they hope to add this support in a later firmware release.

i've had a bit of a play around today. I thought the fact that it was running in a virtual machine may be causing the problem. I installed Visual Basic Express on the windows 7 machine and I experienced the same problem. The driver polls the PLC, the PLC responds but the driver returns invalid data. This seems to rule out virtual machine causing the problem and points to a bug in the driver i suppose.

Hi archie,

I changed the code to not throw the exception. I've had a look at the packets in wireshark, and the correct value (207 or 0xCF) in the holding register is being returned in a packet.

i'll attach a screen shot

Hi, I'm trying to communicate to a mirco 850 using modbus TCP. I have to of the variables mapped to modbus addresses within the processor. But keep getting an unhandled exception:


    Private Sub PolledDataReturnedValue(ByVal sender As Object, ByVal e As MfgControl.AdvancedHMI.Drivers.Common.PlcComEventArgs)
        Try
            Value = e.Values(0)
        Catch
            DisplayError(e.Values(0) & "-INVALID Value RETURNED!")


Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

any ideas? thanks
