It was not difficult to communicate a Koyo PLC with VTScada by means of Modbus TCP, being both, PLC and VTScada in the same LAN.
However, I have not been able to communicate them when the PLC is connected to a router outside the LAN of VTScada.
I typed a public IP address and the PLC port number when configured the TCP/IP port in the VTScada.
The resulting value of TCP/IP Port is -10,06
Hi,
I am having an issue connecting to a Koyo DL330 PLC via serial. I have it setup with the correct station addresses and COM port parameters, and it appears to be reading my register R16 correctly. However, writing to the tag fails. Sniffing the serial packets, it appears that the driver is trying to pull data from 2 8-bit registers when I only want to pull from one and I believe this is w

Some people have been having an issue connecting to the Microsoft Store and downloading the Excel plugin. A lot of these we have found are because of the Excel build. Note that Excel can be up to date with security patches but still be behind on builds.
The add-in currently requires what is known as the ExcelApi 1.4 requirement set which is available in build 7870.2024 or later, so although y

For a school I work on three small PLC controlled processes supervised by separate VTScada applications to manage
some food processing equipment (evaporator, powder dryer machine, autoclave) that the students have to learn to work with.
Is there a report tool for VTScada that enables me to document the details of the tags of these applications in an organized way for the project document

We are trying to create a report for documenting the duration a sewage lift station is overflowing on a day to day basis.
We have a calculation tag setting the overflow setpoint, and an alarm tag running the trigger of "wet well level > setpoint". Followed by a logger tag monitoring the state of the alarm tag, logging at every 60 sec.
When we run daily total reports on the logger

So... in the past Calculation tags have been used to create Color tags.
With VT12 this can be done using the Universal IO Tag: String Calculation but it seems that most objects object to picking String calculation tags { see what I did there }. When picking a color for a box and you select tag and go to choose a tag, it looks for numeric tags. Interestingly, you can select the tag in the lef

The VTScada help file indicates that the RadioButtons function should be called using the Dot notation:
\System.RadioButtons(.....);
When I attempted this implementation the radio buttons did not show up in my display. After verifying my variables I tried using the "\" notation:
\System\RadioButtons(......);
This worked.

How do you log an analog status with a logging dead band and also have it log every hour when the value don't change?
I am looking to display the following VIC Client information in a project:
Server Name client is connected to
Client Name
Logged in Windows username that the client is running on
For item 1 (Server Name) I am using the following expression which is working fine: \DisplayManager\RootSession\Name
How would I reference items 2 & 3 above?
Is there a way to resize the horizontal buttons widget for a selector switch tag? It seems like it would be standard practice to have some user set-able parameters in the properties dialog for setting the width and height of the buttons, but there is not and the buttons are just too small.

Hello,
Getting error code 33,028 when trying to connect to Siemens S7 Driver. I'm using VTSCADA Light Version 12.0.04.
Any Help is Appreciated

Open the PLC project in the S7 TIA Portal software.
Go to Project View
In the Project Tree window, select the device that is causing the error.
Hit Alt-Enter to bring up the Properties dialog.

Hi, I would like to put a numeric entry box somewhere in my application so that the alarm parameters (like low alarm setpoint) can be changed without the user having to go into the tag properties. Is it possible to reference these parameters outside the properties box? for example like how you can reference a tags value by using \Value
If that is not possible then is it possible to create a t
Does VT have the ability to publish data to an MQTT broker?
Do you have a timeline to implement Client Drivers for MQTT and OPC UA?
Not that I really want to use MQTT but these two look like the future of interoperability between PLC platforms, serial servers, and older oddball devices.
I am using KepDirect as an OPC server. I have disabled windows firewalls and can successfully ping between computers.
When I go in VTScada Lt to create a new OPC client, it doesn't see Kepdirect as an option in the pull down menu. Any help?
UPDATED ANSWER - YES! In addition to OPC DA, VTScada now supports OPC UA Clients in VTScada 12. See post below.

Has anyone experienced issues being online with an Allen Bradley PLC, causing VTScada to slow down or even lose communication at all? Doesn’t really cause any major issues (yet) but I’m curious if anyone else has seen this, thank you

I want to write an expression on "digital status" tag. According to changing in value of digital status tag, different text should be shown.
As like, If digital status tag value is 0 then it should shows 'disabled', If its value is 1 then it shows 'running', if tag value is 2 then it shows 'blocked', if the value is 3 then it shows 'unknown'.

Looking for the best way to configure resolutions between 10 pack applications and various client size displays.

The High Performance HMI Handbook (Scada Bible) suggests that Faceplates should have a reserved spot on displays that change according to the item selected on the display.
Everything on the screen is selectable, and when selected the standard faceplate for the element appears in a reserved “faceplate zone” rather than floating around the screen obscuring the graphic.

Good morning,
Little quirk I noticed this morning - When using the Vertical Analog Bar High Performance Widget (VT12) the setpoint only allows you to choose a tag. It should allow the selection of a parameter, linked tag property or expression.
In my particular case I wanted to select a linked tag. This was accomplished by just choosing the tag (that I would like to have linked too) and t
We are preparing to upgrade our software from 11.3 to 12.0+ and I am looking for any information that we need to know before upgrading? (i.e. are there any windows updates that don't play nice with VTScada v12?, any major changes we should prepare for going from 11.3 to 12?)
Also, as a secondary question, is it possible to launch our application on a different PC/Server and run it as if it we

What is the best/easiest way to manually disable comms to a device that is missing? I have devices that are offline at times and I want to optimize comms by preventing the driver from trying to constantly attempt comms to a device that I know is offline. Is there a setting I can toggle? Thanks.
I believe I know the answer to this but figured I'd ask anyways. Is it possible to do a lookup table in VTSCADA?

Even if I have to do something external and pass the result back into VTSCADA. Can VTSCADA read from an Excel spreadsheet through scr

We have 4 computers on the same network at a single location, none of them have internet access and the times on the computers will tend to float away from each other. Is there a way to sync all 4 using VTScada somehow? Basically just need to have one common time across all stations if possible.
I am looking for some direction on creating a Data Grid in VTSCADA
that can poll from the historian.
There is an example in the Oil & Gas Suite for the flow computer history.
Any help would be appreciated
