The Process Analyst includes an interactive zooming feature allowing operators to fine tune how much they want to zoom in or out by dragging the mouse against the horizontal or vertical axis. * Replay trends and alarms by automatic scrolling through historical data. * Fit the span to current/next/previous hour, day, month, etc. * Directly enter a start and/or end time. * Change the time-span to a user-defined value. * Change the time-span using a pre-defined list of spans. * Drag the pane backward and forward through time. The navigation system provides ultimate control over the data for display:
An indication is also provided of when the alarm was acknowledged by the operator or whether it has been gated/disabled. For example for an analog alarm the user can select a different colour for each alarm state such as low low, low, high, high high, deviation and rate of change. Each pen in the display can be individually customised in terms of colour, quality styles, sample markers and even the way data is requested.
Some areas worthy of further comment are:ĭifferent pen types have different attributes, all of which can be assigned different styles. The Process Analyst includes many features including the indication of daylight savings time, accuracy to millisecond resolution, customisable toolbars, rich printing and saving of all display settings for easy recall. The ability of the Process Analyst to display such rich information requires it to have an easy-to-use, yet powerful navigation system. Rather than having to compare a separate historical analog trend display with an alarm summary or log printout, users can simply view them all on a single integrated display.Ĭomplete flexibility is provided to the operator on how the pens can be displayed, for example they can be overlaid or stacked and any pen can be placed in different panes to reduce clutter and make the display easier to read. Process Analyst allows operators to analyse the cause of process disturbances by bringing together trend and alarm data, which is traditionally stored separately. For example, if an unexpected incident occurs, an operator can create an on-the-fly Process Analyst view which compares pump run times, pump fault alarms, flow-rates and valve settings instead of having to look at four different sources of information." In the words of Paul Donald, the telemetry officer at Central Highlands Water, "The Process Analyst eliminates the need for engineers to build custom analysis screens. The reason for this is that analysing data in the past has always been time-consuming.
Whilst all HMI/scada systems collect and store large amounts of data from the site, plant or facility, very little time is spent analysing it.
#Citect process analyst pen assinment upgrade#
The company reports a positive response to all the new features, but the feature that has generated the most excitement was the Process Analyst - with many users indicating that they will upgrade their existing CitectScada system to V6 just to get their hands on the Process Analyst. Over a period of weeks Citect demonstrated CitectScada V6 to many of its distributors, CIPs and users. The issue was therefore resolved by specifying the flag "RegexOptions.CultureInvariant" in the call to Regex.IsMatch which would then correctly yield a list of matching variable tags.CitectScada V6.0 has a number of major features, including an innovative tool for analysing alarms and trends, zero-maintenance Web Client, support for true colour, hundreds of new symbols, longer tag names, time-stamped data and custom alarm filters. By default however, when the regular expression engine performs case-insensitive comparisons, it uses the casing conventions of the current culture to determine equivalent uppercase and lowercase characters. Searching for variable tags is implemented using Regex expressions to find a match in the input string, which in this case comprises of tag field names, such as "iodev". This was due to the way in which the letter "i" is treated in Turkish where the uppercase variant is the dotted "?", as opposed to the lack of a dot in English.

When a customer was operating CitectSCADA under the Turkish locale or had manually set the regional format of their machine to "Turkish (Turkey)" a variable tag search in Process Analyst would result in error code 0x1000019E and no matching tags would be returned.
