Hello everyone,

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

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

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).

I believe I will need to do this using sc

Scenario:

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

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.

Allen Bradley tag creation, if I create a tag for Bool in program, how do I set up address for tag? video is different than what I am seeing.

This is in Softlogix PLC simulator.

Single Application on 3 different Servers that are connected via radio link.

Call them ServerA, ServerB, ServerC

3 PLCs (actually more but this is good enough) each PLC is located in proximity to its similar server

Call them PLCA, PLCB, PLCC

Default configuration is ServerA - if primary does polling to PLCA, PLCB, PLCC. If ServerA goes down ServerB takes over all communication a

For Testing Purposes, I would like to Enable or Disable an Automatic SilenceSound() Function so that I hear 5 seconds of the Alarm Alert sounds and then they are Silenced without Operator intervention. I don't want to Acknowledge or take any other Actions.

Any suggestions are much appreciated!

Thanks, Paul H. Bott, P.E.

With Analog Status you have High and Low alarm setpoints built in so you don't have additional setpoint tags go against your tag count. How do you then refrence these setpoints inside the digital status tag to a numeric entry so that users can changes these without having to go into tag browser?

Is this the design that for adjustable setpoints in HMI it requires tags (that go against the cou

Hello,

Currently we are on the way to deploy APQP process with our supplier for my company automotive project. There are something as below:

Sample should satisfy DIM,Function & Material, the problem is i don't know how to define those samples i

Hi there,

I have recently ventured into trying VTSCADA and I really REALLY like it.

I use scada systems for very simple lab based data aquisition and control. Very seldom more than 15 tags.

My challenge is that I need to aquire a timestamp ONLY when a certain tag value changes. The tag is basically a totaliser (Analog input from MCU). This is very simple to do in the likes of SCADABR

As described here

Distributed Local Historians – The County was also concerned about the potential loss of data should the connection to remote sites be lost. In response, MPE configured the application to allow for use of VTScada as local HMIs at all remote stations. Once VTScada is deployed as a local HMI, if the station is cut
