If there no errors, alarms or events, the display reads Normal. 2.7.1 The alarm status bar Figure 2-6 Status bar with reference to pending alarms If an alarm is indicated in the status bar, the Pending alarms hyperlink will take you to the Alarm viewer (see Section 4.1). 2.7.
3 Navigation You can use PX Web to read and edit existing items or to enter new data. This section also describes the procedures for logging in and out, first steps and navigating from one item to another or navigating within a given item: • • • • • • • Section 3.1 Hierarchy structure Section 3.2 Loggin and loggout Section 3.3 Home page start Section 3.4 Navigating down one level Section 3.5 Navigation on the same level Section 3.6 Navigating Up one level Section 3.7 Navigating several levels up 3.
Before you can start work, you must log in. Note You need to log in separately to each site. This also means that when you have finished working, you must log out of each site separately (see Section 3.2.2). Location Select the required site from the dropdown menu. User name Enter the user name. Password Enter your password. Confirm your input by clicking Login. Click Rescan network to find and display all sites in the system. Click this button if a particular site is not visible.
The structure of this page is as follows: From the dropdown menu, select the required option. For access to a specific item, you may need to click your way through the various levels within the hierarchy. Via the dropdown menu, you can jump from a lower level directly to a higher one, omitting one or more intervening levels. However, this is only possible when moving from a lower to a higher level. Confirm your selected option by clicking Go.
3.4.2 Level 2 Figure 3-3 One level below Functions Select from Alarm viewer, Alarm & event history or Add new graphic page. All three options are at the same level. For the purposes of this example, click Alarm viewer. The next page down will open (level 3). You will see all the alarms listed on this page. The example shown comprises one page of alarms on the same level: 3.4.
3.4.4 Lowest level Fire detector 1 with long name Figure 3-5 Object data In this example, you have now navigated to the lowest level, and can only continue by moving to a higher level, in other words, by navigating the same path in reverse, using the Up button. 3.5 Navigating on the same level The navigation field shows how many pages a given option contains, and indicates on which page you are currently located. This field is only displayed if there is more than one page.
4 Alarms, events and history The display of alarms and system events, and their acknowledgement and further manipulation are important features of PX Web. If a common alarm was set up in the engineering phase, you will be able to use the associated dialog box to acknowledge and/or reset all the alarms “below” that hierarchical level. • Alarm view, see Section 4.1. • Alarm and event history, see Section 4.2. 4.
Fire detector 1 with long name Figure 4-1 Alarm viewer page An alarm entry consists of the alarm symbol, the name of the object affected and the date and time. You can invoke further information by clicking the ? button. Air Handling Unit 1 \ Fire detector Figure 4-2 Alarm details The properties of individual alarms or events are indicated by symbols: The meaning of the alarm symbols is as follows: Alarm symbols Description Alarm in Offnormal or Fault state Alarm not yet acknowledged.
Alarm symbols Description critical alarm at the highest level, you must also reset the alarm by clicking the Reset button.
Acknowledging an alarm You can only acknowledge an alarm if you have the necessary privileges. The read and write privileges for your User group will have been defined in the engineering stage. Click on the alarm entry containing the symbol for an unacknowledged alarm. A page containing the most important information about the alarm will be displayed. Air Handling Unit 2 \ Outside air temperature Figure 4-3 Information about an unacknowledged alarm Click Ack to acknowledge.
4.2 Alarm and event history Select Functions and display the Alarm & event history. Fire detector 1 with long name Figure 4-4 A page of the Alarm & event history This option displays a maximum of 250 entries with the following information: Note • All the most recently received alarms • The most recently acknowledged alarms • The most recent events You cannot acknowledge or edit alarms in the Alarm & event history. To do so, you must switch to the Alarm viewer (Section 4.1).

Figure 4-6 Alarm details Event type Change of state Out of range Execution error Change in reliability Change in device status Change in event enable signal Message indicating elapsed operating time System message Operation message Click Message to return to the page of alarms (Figure 4-4).
5 Scheduler You can use the Scheduler to define time-dependent operating states. Time-dependent setpoint adjustments, by contrast, are determined at the engineering stage. The Scheduler consists of a weekly schedule, see Section 5.1, and one or more exceptions, see Section 5.2: • In the weekly schedule, you can define 24-hour profiles to be repeated week after week. • In the exception schedule, you define days which deviate from those defined in the weekly schedule. 5.
Figure 5-1 Weekly Schedule 30/58 Siemens Building Technologies Web operation PX Web Scheduler CM110757en_07 2017-04-05
5.1.1 Opening and editing a day Click on the required day. The page illustrated below will be displayed. Figure 5-2 Switch times for a day of the week Note You can only define a profile for one day at a time. Repeat your entries for each day of the week. The buttons shown below the list are used as follows: Open a new page with blank input fields. Enter the required data. Click Save to confirm your entry. Click Cancel to discard the entry. Highlight the relevant entry and click Edit.
If you select this check box, the default operating state, as engineered, will be applied until the next time entry. In other words, any inputs in the State field will be ignored. A suppressed state is identified by the mark "----" adjacent to the switch time. In a normal weekly schedule this option has little point, as the default status is defined at the engineering stage, and is not seen by the user. Click Save to confirm your entry. Click Cancel to abandon the process.
Enter the required value in the Value field. Figure 5-5 Set the required value Click Save to confirm your entry. Click Cancel to discard the entry. 5.2 Schedule exception list The next section describes how to edit local profiles. The editing of global data is described in Section 6. Click the Schedule exception list (Figure 5-1 Weekly Schedule) to open a list of calendar entries and locally defined exceptions.
Note A calendar cannot be deleted (Del).). • Local schedule exception with: – Date – Time period (DateRange) – WeekNDay These inputs are described in more detail in Section 6. 5.2.1 Defining a new local exception The New exception dialog box will appear. Select the required date type and confirm with OK. Figure 5-7 Defining a new exception period This will return you to the original window, where the new entry is already highlighted (Figure 5-5). Now define the profile with Edit.
5.2.2 Editing an existing exception After choosing a calendar, you can then edit the local profile. The dialog box shown in Figure 5-8 opens immediately. Highlight the required entry in the Schedule exception list (Figure 5-5) and edit the Profile or Date via Edit. Figure 5-8 Editing an existing exception Select Profile and confirm with OK. The window shown below will open: This is where you define the 24-hour profile and the Priority level of the exception.
Highlight the relevant entry and click Edit. The selected page will open. Change the Time [hh:mm] and, if required, the State When you reach the last time entry in the exception profile, always remember to select the Disable check box. From this time entry on, the exception profile will cease to be active and the weekly schedule will be resumed. However, if several overlapping exception profiles have been defined, the exception profile with the highest priority level will apply.
6 Calendar The calendar contains global exception days, such as works closures and public holidays, for one or more plants. Several calendars may co-exist. The exception schedule contains two kinds of exception: • Exceptions which are stored locally in the time schedule and apply only to that specific time schedule; these are identifiable by the date information (see Section 5.2). • Exceptions which are stored in a global calendar object and used by various time schedules.
WeekNDay The exception applies when the specified month, week and day coincide. "Week" in this context has the following meaning: Week-1: 1st to 7th day of the month Week-2: 8th to 14th day of the month Week-3: 15th to 21st day of the month Week-4: 22nd to 28th day of the month Week-5: 29th to 31st day of the month Last week: the last 7 days of the month These "weeks" are thus quite different from a normal week defined by the period "Monday-Sunday".
7 Editing values The values you are able to read and edit will depend on the following two criteria: • The objects of which your plant consists • Your user access rights By virtue of the above, it is impossible to provide an exact and binding description of the values which you can read and edit. In this section, we have used an example, to describe how to modify and force a given value. 7.
FIgure 7-2 Editing a value Edit the value to your requirements and import it into the system by clicking Save. Note The question of which values can be edited individually is defined when the plant is engineered. 7.2 Note Forcing a value, based on an example "Outside air temperature" You can only force a value if you have “Expert” access rights. Forced control changes the values of inputs and outputs to a specific (fixed) value. The measured value is ignored.
Figure 7-4 Present value The forced value is identified by the adjacent “Hand” symbol. To revert to the original measured or calculated value, proceed as follows: Click the Outside air damper value (Figure 7-4) and then click Release.
8 Trend data Trend data provides important information about the processes in a building automation and control system. The trend data is saved in the buffer of the objects TrendLog and TrendLogMultiple in the automation station, from where it can be retrieved for further use later (offline trends). In PX Web trend data is displayed in table or graphical form. It is also possible to export the data. 8.
Some parameters in the TrendLog and TrendLogMultiple object can only be set under certain circumstances, e.g.
8.2 Displaying trend data The values logged by a TrendLog or TrendLogMultiple object can be displayed in two different views. The first form is the list form. Form the list view, you can export the data as a CSV file. The second view is the graphic form, which shows the progression of the trend data. 8.2.1 List Click Trend data to display the trend data list. Figure 8-2 List of Trend data The list form displays the exact time of an event and the value / the values at that time.
8.2.2 Graphic Click Trend graphic to display the trend curve. This view is available only for Trend object, not for Multiple Trend object. Hinweis For the graphic view JavaScript is used. The correct view of the curve depends on the possibilities and options of your browser. Figure 8-3 Graphic display of trend data The graphic form gives a useful view of the trend data. On entering the graphic view the latest 200 values of the buffer are displayed.
Figure 8-4 View option You can move the window over the entire current content of the log buffer using the horizontal slider. Here too, a maximum of 200 samples are displayed. Figure 8-5 Scale option You can choose the y scale. The entered value will be rounded to the next integer. Click Apply to to make it effective in the graphic view. Note The processing may take considerable time, indicated by an animated icon.
8.3 Exporting trend data The logged trend data is stored in a data export file. PX Web saves the data in a file with the extension .CSV (character-separated values). The data fields are delimited with a semicolon ( ; ). The file can be saved on a PC and displayed with a text editor or imported into a spreadsheet program.
9 The heating curve The heating curve is used to determine the flow temperature setpoint for weather-compensated flow temperature control. Click the Heating curve hyperlink to open the heating curve window. The location of the hyperlink and its name are determined at the engineering stage. You can enter or edit values in both the graphic view and the list view (see Section 7.1). Click List view of heating curve or Graphic view of heating curve to change from one view to the other.
Radiator exponent The following values are recommended as radiator exponents: Radiator-type systems 1.3 Plate-type heaters 1.2 – 1.3 Convectors 1.25 – 1.45 Underfloor heating 1.1 Enter the required values in the input field and confirm them with Save.
