The xA System provides a common operation and configuration view for MOD and other field devices and software options.
Page 20 Document Overview Section 1 Introduction Operation Refer to the following operation chapters for instructions and reference information related to runtime operation. The desktop will be shown and the Workplace Login is launched. Page 24 The permitted actions in the open windows are controlled by the permissions of the logged over user. The log over only affects the xA System permission.
Windows security is still the same as the user logged in. Page Operating Overview When operator interaction is required, the operator interface is supported by the displays described in the following chapters. Page 26 Accessing Displays Section 2 Getting Started Accessing Displays Using Graphic Displays Graphic displays may be associated with an object with context navigation to trends, faceplates, and overview type displays. Overview graphics can provide a panoramic view of the process and can provide one-step access to critical displays.
They can be made the software equivalent of the Page Selector Alarm Panel with the capability to monitor alarms for different areas and groups from one display or have target blocks that can initiate a TCL program sequence state or status transition.
Table 1. Page Printing Displays Printing Displays Section 2 Getting Started Printing Displays To print the active window of a display, use the Print Screen key to capture the screen, paste the image into an application such as Microsoft Word and then send it to the printer. For best resolution, maximize detail displays to full screen before printing. In addition, tuning and engineering procedures are described. Control and PID Loops Figure 2. Device loops detect the device state. Select the command, mode, and state process values box to access the device loop faceplate.
Only device descriptor state values of 0 to 15 are allowed. If the Enable Access Restriction configuration is set to Yes, then device commands are not allowed while in auto shaded buttons. Figure 8. The faceplate for a Special Device type only shows four of 16 possible outputs.
Page Loop Faceplates A tag descriptor can be up to 24 characters and normally explains the purpose of the tag. The descriptor defined during configuration and then imported into the xA system, after it is imported it is no longer updated. Some of the actions available in the operator area include: change auto or manual mode, change computer mode, and change set point mode a shaded button does not allow change. In auto, the setpoint and ratio can be adjusted. If shaded, switching to Auto is not allowed.
Manual Switch to Manual from Auto. In manual, the output can be adjusted. Bias value can be changed locally while in this mode. Remote Bias Switch to Remote Bias operation. Local Ratio Switch to Local Ratio operation.
Figure To change the bottom number on the Y-axis, select the Bottom of Range field and enter a new number. Click on the Auto Expand field to dynamically change the range limits to a new limit value as new values cross the limits. Control parameter changes for a loop tag that are made from these displays allow you to monitor the results of both manual and auto control operations. As an alternative, you can use the control slider to change the setpoint or output value up or down.
Again, you may have to adjust some preliminary parameters as a prerequisite for changing the parameter that you actually want to change. Select the entry field, and then enter the new value via the keyboard. Press Enter to accept the new value. Value is reset if focus is lost. Entered value goes red after it is written to the controller.
Once the new value come back from the controller it changes back to black. Field State is a read only field and cannot be changed.
You can change the values of the status parameters by selecting the block and entering a new value in the fields provided along the bottom of the Loop FCM Display. If the save process is not successful, a message describing the problem is displayed. Select the device block. There is no FCM Templet for device loops.
Alarms Alarms based on the process measurement are defined as part of the loop. Continuous loops indicator and calculator for example detect alarms on the measured variable. Page Alarm Priority Alarm conditions may also be indicated audibly by a.
WAV file. Various combinations of audible and visual alarm indication can be obtained by configuration. Page Alarm Acknowledgement Section 3 CCF Displays Alarm Acknowledgement mean that two separate alarms are configured on a single variable with either two high or two low trip points.
The high, low, and rate of change alarms are extensions of output limiting. Generally, a group has up to 12 control loops or up to 36 indicator loops or a combination of both. Control loops assigned to indicator targets provide limited information and cannot be used for control. Page 64 Group Status Display Section 3 CCF Displays The trend graph represents one division of trended data 60 sampled points from the engineering low limit to the engineering high limit.
The most current trend sample is on the right side of the graph. Trend data is only displayed if the trend rate is enabled not 0 for the tag.
Only device descriptor command and state values of 0 to 15 are shown. Use the loop fcm if your configuration uses greater values. Group trends are displayed on three full-width graphs. Each graph shows trends for up to four loops, and is accompanied by the corresponding status blocks. The most current trend sample is on the right side of the grid. Control functions within the block depend on how the loop is configured and user authority.
The status blocks occupy the right one-third of the screen, and the graphic occupies the left two-thirds of the screen. Status blocks operate as described in Group Trend Status Blocks on page The primary event group page is a filtered set of event attributes such as state acknowledged and active and type operator action and process related.
Area Status Display One to three indicators are displayed on one status line, Figure 26, depending on the configuration. Each indicator line segment is context sensitive to its own tag. Measured Measured Device Variable The measured value bar graph also indicates the setpoint value with an orange triangle on the bottom of the graph, and it indicates the input high and low limits with red triangles on the top of the graph.
The page can provide further filtering of the events but cannot expand beyond the filter of the event group. When the Area Alarm display is first called up, the primary filter is applied and then the filtered list of tags assigned to the area is applied.
The graphic configured for that aspect gets displayed in the Area Graphic display. Sequential control operational displays support monitoring and control functions for TCL. These editors are available with AdvaBuild. Messages which require a response cause the originating sequence to pause until an appropriate response is entered.
Sequence Type Schedule, Procedure, or Operation. Access the Unit Detail Display of the unit where the recipe is to be downloaded. The operator can then resume or abort. Most of the runtime changes made to a sequence are done from this display.
Step data fields show the current step, next step, step time the time spent executing the current step , and pause step or the step on which the program pauses in semiauto mode. The next step can skip or repeat other steps as necessary. Pause Step determines at which step the sequence stops and waits for an operator response.
However, the write does occur and the first scan shows the old value and then the next scan shows the written value.
