I created a digital control tag that is interfacing with an Allen Bradley Micrologix 1100 PLC with the DF1 driver. When I select the newly created button I receive an "Error Code 256" for this button. What does that error code mean? I have several other buttons on the same screen controlling bits in the same plc and without any issues.
I'm a beginner with raspberry pi and also to Python language. I'm trying to use the raspberry pi 3 for industrial application and for that I've connected quite a few sensors (temperature, humidity, co2 etc.) I'm successfully able to get reading from the individual sensors and wrote a structured program with few functions related to each sensors to get reading from all the sens
When using Parameter expression to Set High Scale value under the scaling tab of the Analog Status tags it slightly alters the value from the PLC's Tag value. The actual value is 16.4 and is just a stored REAL value not a calculated one.
Also I have to perform a mathematically pointless calculation to get the widgets to use "Tag scaling values"
I'd like to monitor, decode, and "interact" with a Modbus RTU device. Nothing complicated, I don't think. When I say interact the "linking" of meters/graphs to some of the registers etc would be really a nice to have and that seems to be inherent to your application.
Question: Is VTscada Light the product I am looking for?
I reviewed the manual and looked at the software after insta
The text at design-time in the Multi-line text widget is wrapping, but the text is all on one line with no wrapping at runtime; how does one get the text to wrap in the Multi-line text widget at runtime?
Hi Guys. I'm installing VTScada in place of another SCADA system and need a way to replicate the old watchdog functionality that they were using. Currently, their old SCADA system toggles a bit for each RTU, based on a set interval, and that bit is tied to a point in the RTU that will cause an alarm on site, if the bit stops toggling (loss of comms).
One of our clients that we recently converted from WW (yay!) is going to upgrade servers soon. Wondering what the method is to transfer existing license from one PC/Server to another. The license was just purchased and is still under support. Thanks!
Our application style is a container one having three windows:
Top: Toolbar with several subsystems, each having submenu action buttons. Action button change the graphic represented in middle window
Middle: Graphic application area
Is it possible to create a VTScada application with this shape?
We have been unable to configure our ModbusTCP driver to 0 address offset. Can you please advise? We did the following: 1) Make a Context Tag (which will be the parent of the TCP driver) 2) Go to Settings, and add a property: "ModiconTypedAddr1Offset". We set the value to 0.
We have also been unable to write to coils. Could you provide an example of how to write specific bit
Redundant server configuration (Primary + Backup)
Primary server online and working OK
Backup server ready but in standby mode (no coms/history..)
Several Operator Workstation on local network
The operators normally logged in Primary server
Then, primary server shuts down by any anomaly or forced event.
The question is how the Operator Workstations recover connection with Backup
I am new to VTScada Successfully used json/xml driver to read the data from external Device But i am stuck in how to send data ? For example i want to send http command when button is pressed ! Any ideas ?
I am having a problem reading tags from my OPC Server using VTScada Light. The server is located on an external PC and the connection to the client PC is made through DCOM. I know the DCOM configuration is correct because I can use Matrikon OPC Explorer on the client PC to read all the servers and tags on the external PC. I just can't replicate this within VTScada. This first screensho
This is a question I was asked by a customer recently:
Q – What is the easiest way to do a daily pump run report for 5 years?
A – The built-in Pump Activity Report should work. It provides you with activity over the entire time frame, not daily over x years. You'd have to run it for the previous day and then have (5*365) = 1825 previous periods. Not allowing for leap years.
