TCS 4.20
Trends Management Program
for Data Acquisition and SCADA Networks

TCS is a high performance, extremely flexible system for monitoring trends in time-series data. TCS was expressly developed to help Remote Controls operators and managers to visualize and understand the state of their plants, but it can be used for every other kind of activity where there are time-series data to display and to archive as for example the financial analysis.

TCS has two components, a collector and a grapher. The collector runs at configurable time interval, and stores data into a datastructure. Later, when you want to check on the data you have collected, you can use a the graphics interface to view graphs of the data.

Furthermore with the spreading of monitoring systems, like SCADA systems, often the need raise to control data coming from many acquisition systems and memorized on different data bases, sometimes residing on different machines in one or more networks. The program TCS was developed to show the trends of these data using a single program.

The data can be external data, collected from one or more acquisition systems of a net and/or internal performance data of servers. In a general way the program can manage every kind of values, stored and periodically updated, in a Data Base which can be reached form the computer where the program runs, via SQL queries through the opportune drivers (ODBC and/or BDE) .

It can be useful to follow the trends of data mainly over a long period of time and to store important data for successive review. It can be useful also to follow the relevant parameters of a server to control and optimize the performances in peak activities periods, as can be a sustained alarms period in a supervision system.  The data can be displayed, stored, printed and exported either in graphical form either in numerical form. The program includes spreadsheet functions.

It allows to visualize, in one single page or in multiple pages, different trends graphics. Every graphic can display a maximum of 6 curves. The maximum number of points data the program can manage is 10,000. The trends can be visualized on hourly, daily, weekly, monthly and yearly basis. The graphics display the points values, as they are coming from the field for the hourly trends, while the other graphics report, on selection, the arithmetic average or the weighted average (hourly average for daily and weekly trends and daily average for monthly and yearly trends). The weighted average is based on the time interval between an upgrade and the next .
The data can be only visualized or also memorized in a historical archive.

 It is possible to configure the system in such a way that if a parameter is in alarm state (the state is acquired from the data base, together with the point value), the graphics containing it will be visualized automatically, in the case it were not already displayed. The data are allowable also in spreadsheet form, for eventual calculations.

The data acquisition is taken by means of SQL queries, from one or more data bases. It is possible to configure just to 10 different queries, each with one associated timer which allows to set independently the acquisition time for the cyclical interrogation. As alternative or in addition the data can be acquired through a data file.

The Internal Data function, which works on Windows NT/2000/XP systems, have been introduced to follow the system performances. It works as Performance Monitor taking the system data. Its Configuration panel appears and works like the one of the windows program Performance Monitor. It can be used to monitor the system load during peak alarm state conditions, when a lot of signals change it state to alarm or other critical situations. It can be used also to optimize system configuration.

The Internal Data are taken from Performance Monitor and all the parameters available in the Performance Monitor can be followed in the time.

A dedicated timer allow to configure the time interval at which the configured data have to be updated.

TCS 4.20 is  largely configurable either as presentation either as functionality.

A simulation mode is present in which data are generated internally by the program producing random values between the configured maximum and minimum values of the points.
