I want to use an "always high" digital tag sent from VTScada to the PLC as a comms status bit.
I've tried creating a numeric calculation tag and entering the PLC bit address in the address field, but this doesn't work (I'm assuming because the numeric calculation only outputs analog, but correct me if I'm wrong).
I have tried to use a digital tag with start condition, but not sure what
Under "configuration" -> "properties" -> Display Tab, under "Application Window Behavior" I have checked "Resizable Window" and "Constrain Aspect Ratio". The image displays fine on a large screen. When using a laptop screen, however, only the upper left corner of the screen shows, and there are no scroll bars to center the window. How can this be fixed?
I am using a Siemens S7-1200 with VTScada and the Siemens TCP driver. Occasionally, certain tags will be modified fine in VTScada, but they are not written to the PLC program (although they should be). Other times they are changed correctly. It seems to be somewhat random. Would appreciate any advice anyone could give that might be causing this. Thanks.
We are trying to configure a firewall between the primary and the DMZ (Pivot) server. The DMZ (Pivot)server will provide read-only remote access to operators. We are licensed for 25K tags. What is a good estimate for throughput between the primary and dmz server?
I have an I/O tag of length word in VT scada with an output address to a register in the PLC. I want to set/reset a bit at a desired position in that tag if an alarm status tag is true. What is the best way to do this?
I've created a Custom Type that contains five analog tags - Value, EU_Max, EU_Min, L_Alarm, H_Alarm. Their PLC addresses are based on a custom Parameter called 'BaseAddress'. Address expression example:
\baseaddress + ".Value"
I've also tried:
Pickvalid(Concat(..\baseaddress, ".Value), "")
If I open the Historical Data Viewer page and turn a tag's trend visibility off by clicking the eyeball icon and then close the page, the trend visibility is set to disabled globally. You go to a page showing that tag's value and click on it to open the plot and it is not visible. Not only that, but any other user will also have that tag's plot not be visible.
I have created a new Type in Context tag and created this with Create new Type. Its added in Tag list as a new Type tag. I want to enable/disable this new type tag for users.
I have added new type tag named as "MyType". I want to Enable/Disable this tag type for different users. (Users with no permission to show this tag type are not able to visible this tag type in tag list)
Hello, I am new to VTScada. I have an Alarm Word from the PLC, where each bit represents an individual fault. I'd like to read the entire Alarm Word as a single tag in VTscada and create alarms for each individual bit. I have found the expression Bit([HMI Alarm Word],2) for example to work as an expression, but I'm not sure where/how to enter this to create the Alarm. Thanks.
Is there a way to remove the Notpad's from the popup HDV. For Example if each site has a notepad in the Folder it shows all them in the HDV. i am Okay with having the System Notes in there but it is just getting out of control with every other one.
