The Modbus User Map Register Settings are correct and the frequency tag is working correctly; however, tags IA, IB, and IC are not updating properly on VTScada. Shown herein.

Hello,
I want to simulate the environment of PLC and HMI communication on VTScadaLight using GE Fanuc Series 90 driver so that I can run a virtual PLC using port 18245 and HMI on the same computer. Can anyone please tell me whether it is possible and if it is then how should I work it out.
Thank you.

I find the "Alarm Configuration Structure" in the webpage .

There is a "Custom" in the structure. Where should I key in value into the "Customer"? I can`t find a place in the "Alarm Properties TabPage".

Thank you.

VTScada can use ActiveX like Shell.Explorer in the help page.
https://www.vtscada.com/help/Content/Pro_Functions/ActiveX.htm?Highlight=activex

How can I write a ActiveX that does something for VTScada? What is the interface or protocol? I need usermanual about this. Thank you .

After obtaining a certificate and verifying your domain, GoDaddy will supply you with the following files:

generated-private-key.txt
generated-csr.txt
Security Certificate.crt
(“Security Certificate” would be replaced with random characters)

You should be logged into Windows as an account with administrative privileges for these steps to work.


Place those files

HI

I have designed a Tag group, there are about 50 tags and a modbus driver, a serial(TCP/IP) port in the group, each tag mapping to a same table to the real device.

After I copy tag groups and set different station ID,
When I connect to one device, all tags read values in one second,
when I connect to two device, some tags read values in one second, but some tags read values in
