Support Questions / Preloading Components

« on: November 09, 2015, 05:16:35 AM »

Hi,

Is there any preloading technique at startup that includes all pages in one Application?
I found out when using OpcDaCom, the data is quite slow to be retrieved at the first time opening page.
So, I am thinking to put this loading time in the beginning of Application instead of when opening the particular page.
Thank you.

Best regards,
Andrew

Feature Request / BasicDataLogger OverwriteEnabled

« on: September 08, 2015, 02:04:32 AM »

Dear Archie,

Is it possible to add OverwriteEnabled property in BasicDataLogger?
Currently it only can write up to MaximumPoints, it would be nice for datalogging to have this option.

In addition, for BasicDataLogger2, it would be very good if there is 'label' property when declaring PLCAddressValueItems.
And these labels will be printed in the first line of datalog result.

The 2nd feature ('label') is not very important, but the OverwriteEnabled might be very helpful.
Thank you.

Best regards,
Andrew

I am using AHMI-V398t, I have 2 forms: form 1 and form 2.

Support Questions / OpcDaCom Issue - AHMI_V398t

« on: July 24, 2015, 05:14:38 AM »

Currently I have issue with OpcDaCom.
I have developed using OpcDaCom since 6 months ago and worked properly in my laptop.
Now, I run the same program in new installed computer, but unable to work.

The error message appears in BasicLabel:
"CoCreateInstaceEx Access is Denied"
This error comes out only once, then the following error message appears continuously:
"Object reference not set to an instance of an object"

This is strange because I run the program at the same time in my laptop, but no error message.
The OPCServer indicates correct value in both computer and laptop, but unable to read with AHMI in computer.

Please help to advise regarding this issue.
Refer to attachment for the OpcDaCom Properties (it works in laptop, but not in new computer).
Thank you.

Best regards,

Support Questions / InvalidComObjectException - OpcDaCom

« on: June 09, 2015, 02:03:42 AM »

Dear Archie,

I am using V398m, and OpcDACom communication protocol.
I got this InvalidComObjectException error 'sometimes', right after I execute Application.Exit()
It's actually not a major problem as in this case User wants to exit anyway.
But, it would be better if it's not happening at all.

Code: [Select]

Try
   Application.Exit()
Catch ex As Exception

End Try
Please advise if you have explanation or trick to prevent this error.
Thank you.

Support Questions / DOUBLE WORD - WAGO PLC Modbus TCP

« on: February 02, 2015, 10:37:22 PM »

Dear all,

Does anyone know how to handle DOUBLE WORD (%MD)?
I am using version AHMI 3.97e and WAGO 750-881.
I am able to communicate + read & write data between WAGO and AHMI.

However, when using %MD, unexpected result occurs.
It will show very large data, described in the following scenario:

I modify value of %MD1200 = 1
Then, in AHMI, the value is showing 16256 at address 414690.
I expect to get 1 in AHMI, which is the case when I modify %MW1000 = 1
In AHMI, the value is showing 1 at address 413289.

Please refer to attachment for more details.
Thank you.

Andrew
