Is this possible - and if so, how do I set this up? I have tried creating a virtual PLC and put an analog tag with a value in there, but I cannot get a Modbus Client device to successfully connect

Hello guys,

I try to connect VTScada with my AB Micrologix 1000 PLC. It still uses serial port RS232 (I connect with USB converter-COM3).

I have tried Allen Bardley DF1 Driver. But it doesn't work. My PLC type is not available at PLC type list. But I hope they still can be connected.

Could you guys help me please.
Thanks,

Hi,

My VTScada application uses a 3rd-Party database (MySQL). I'm trying to retrieve a tablename using this query:

Hi,

I'm trying to use a C# based dll with my VTScada application. To do so, I'm using The function DLL.

It's working well with integers, floats and strings, but I have to do some gymnastics to get a bool (I use an integer return type and apply a modulo 2 to the variable to get a 0 or a 1), and I flat out can't get any types of object. I'm trying to use a pointer as a return type but I al

Good morning,

I am currently working on a VTScada Light License with the goal of being an historian and data collector for a wastewater treatment pilot unit. I have come across the following issues when it comes to exporting/reporting:

What I can do with the HDV:

Export data for a specified unit time frame (ex: 2 days, 1 week)
Export "Time Per Record" to record every X minutes/seconds

I have the latest Light software. Up and running connected to a Compact Logix running V20 flawlessly. But with my V.28 Control Logix, it will connect long enough to show the connection in the AB Demo driver then disconnects. what can I try?

Hi,

Hi,

Is it possible for each server/station of the same VTScada application to have their own Alarm DB and Event DB?

Or is there any way so that alarms would need to be acknowledged independently on each server/station? So if an alarm is acknowledged on one server, it still shows up as unacknowledged on the other.

Thanks
Victor

Hello, can someone please take a look at the attached screen shots and let me know why there are no values for the tags "T_Room" and "DI4"? I'm connected through a USB to Modbus RTU converter. The TX and RX lights are flashing on the converter, so I know its talking to the PLC. The first four screen shots are from the PLC software. I not sure how the scaling should be set up for analog status
