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 already created the tags for my PLC in VTScada. I am trying to pull the digital status of a device in my system. First I was using Y memory bit, the digital status can be pulled correctly, I can see a value 1 shown on the Tag when that device was on. The Y memory bit address and function code are attached.
Then, I changed the Y memory to C memory bit, the device is still working well.
I have an ultrasonic sensor with range from 40~300 [mm] outputs 4~20 [mA] to my PLC(ClickPLC). I established connection with the PLC and VTScada Light, the value pulled form PLC, is varying from -171 to 700 something with scaling set as 0~100 for both raw and processed.
I tried to pulled data from some other addresses on my PLC which are not used at all, I did get a value of zero. So I assum
since Vt scada has taken by delta electronics,does it support delta dvp 14ss2 rs485 i tried connecting it,or how to link kepserver with vt scada,I am getting data on kepserver quick client but not on vt scada.Seems like some certificate problem.can I get the proper method to do so? thank you, yogesh thakare, Koolaxis LLP.

Hey all, Just looking for some input on modifying the GE series 90 driver to accept symbolic tags. If this can be managed I can cut out an intermediary OPC client and just run everything through VTScada.
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), "")
I am running the micro800 simulator on Allen Bradley's CCW software. It appears that you support micro800 PLC's using the Symbolic CIP driver, however when I try to use the AB CIP driver demo downloaded from your site, the connection blinks green and does not stay on. I have the simulator running on CCW with a basic start/stop logic. Please let me know if there is something specific that I need t
I recently downloaded VTScadaLIGHT in order to test a prototype device. I am writing to Modbus registers 40001 - 40010, and splitting my floating point values into 16 bit unsigned integers. How would I union them back together in VTScadaLIGHT as a floating point value?
ex) 40001 = 16 bit unsigned int 40002 = 16 bit unsigned int
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.
