I am trying to calculate flow rate as a function of change of wet well level over time. I have tried using various tags types, adaptations of Ex 3-17 from the Adv Config Workbook, Intgr and Deriv functions; and everything comes up with some kind of errant data: Intgr gave max scale value, Deriv gave 0. Using the following provided the most realistic results:

"[PUMP_RUN] == 1 ? Latch(AbsTime(

So the system I’m currently working on is already providing me scaled data coming out of the flow computer. This is also in conjunction to the scaling of the raw data at the PLC level for my other analog instruments.

What is the best way to make sure I’m setting up my analog status tags properly so I’m getting the right historical data recording and displaying my data prope

Hello friends, I have a serious problem. VTS does not open on the server. I have two servers, one is a backup of the other, VTS only starts if the network cables are disconnected, clicking on RUN locks in 50% in the final step "Starting tags". Does anyone know how to solve?

Is there a way to get shell execute to be OS dependant.
My ping button wont work in the android client.

We cannot seem to get Alarm notifications to work with Office365. The smpt server is supposed to be, I'm told, but when we have this as the SMPT address using port 587 and TLS encryption we get the following error: "SendMail Error [9]: Server doesn't support authentication"

We do get alarm notifications if SMPT settings as follows: Email Server: {company}-com.mail.protectio

We are working on setting up HMIs (10 pack) for our local control panels; dual servers are setup with application, screens, and tags (designated with areas). We have looked at the tag area filtering literature, but are apparently lacking something on server/HMI architecture as we do not have all the options in "Workstation" and "Section" options in properties.

Is there a best practice for se

If you seem to have lost your VIC graphics after accepting Windows build 1903, we are looking into it. As a workaround, stop the VIC. Open Internet Explorer and clear the cache.

Go to C:\Program Files (x86)\Trihedral, right click on the VTSX.exe and run it as administrator - even if you are an administrator.

Log in and run it once. Close it. You should be able to run it normally from your

I am working with an Omron Cj2H. Programmed analog inputs and reading into a DM. Positive values are performing okay, but as soon as I go slightly negative ( reverse flow), then the number jumps to 65535. This is telling me it is wrapping around. I have tried using negative values in the scaling, but have not been successful at this point.
I can watch the channel in the plc and it remains nega

Hi, Is there a way to edit a Type property from the VT HMI? Some users will not have access to the Tag Browser but may be required to change IP address which is set up as a property of the Site Type. I tried several methods to set up a Linked Tag Widget but have been unsuccessful.

I'm thinking that I may have to script it somehow but want to know if I'm missing something before I go down that

I am building a plant from scratch. The plant has different types of equipment and all I can see in VTScada are various pumps, valves, and motors. Has anyone built or have access to bar screens, conveyor belts, weir gates, or anything else that might be useful?

Thanks in advance!

Good Day Support Team,

Few months ago i built an application running with ModBus communication. On the laptop i made it, it works like a charm.

Then i've installed VTScada on another laptop, and import the project that was on my persoanl laptop on this new one.

i set up the fixed IP address as suppose to be, but i have no communication at all. I can PING the IP of the PLC, so it means

Hello, I am evaluating VTScada for our facility and am working with the scadalight. I have not worked with Omron Plcs in many years and need some information.
My plc has some levels which are stored in a data area (ie D0700). The PLC resides on our network (ie From the program, I do know they set the port to 2120 instead of the default 9600. I am not sure which settings to use
I can successfully pull up the data into Excel using ODBC connection. The SQL statement like

select * from Alarms;

is working perfectly fine. The issue is when I use 'where' statement, I get an error. The following command is giving an error.

select * from Alarms where Active = 1;


select * from Alarms where 'Active' = 1;


select * from Alarms where Active = '1';

I am trying to integrate in a counter and some automated resets. The plant is currently changing the times of shifts a lot and I would like to allow them to configure on the fly. Is there a way I can change the trigger tag using parameterization? If so I cannot find any information on the exact syntax or how to do so.

I would like to know if there is a possibility to get the real-time information of the alarms that arrive in the system, via ODBC, a list of the alarms that arrived in a certain period of time. I've tried to understand the file alarm.db and Alarm.LOG, but it seems illegible to me. Can someone help me?

Dear Dave, Thanks.

Do you mean thru realm we can authenticate other users from same network? if yes then please forward the link to install odbc driver again, the one you sent is not working.

As I know ODBC is to link with third party like xlreporter.

but is it possible to run the application it self from the remote laptop? How, is it thru OPC client and server configuration? is it

Dear all,

I have installed VTSCADA light in a data logger (windows operating system) and link the logger to controller (modbus device) thru rs232.

Is there any solution to access from remote laptop?

Is ODBC or XLreporter provide this solution? is it free or at least demo for testing?
