Configuring SPP monitoring

The user may view and control the current state of set point Also known as SP. The desired value of a process variable. Setpoint (SP) is an analog point parameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. programs in the HC900 Hybrid controller. and UMC800 controllers from one of three monitoring displays. The SPP Setpoint in percent. See also: setpoint parameter. Summary displays allows the user to monitor the first four programmers in a given HC900 or UMC800 controller Also known as remote terminal unit, RTU. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC.. This display provides information about the SP The setpoint parameter of an analog point. The desired value of a process variable. Setpoint (SP) is an analog pointparameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. programmers, including their current state and segment number, the segment time remaining, and a history of the current program.

The SPP Program display allows the user to view the program configuration of a specific programmer. This display is very similar to the Profile Configuration display in that it shows a time-based program of 2 to 50 segments in length, where each segment of the program can be a ramp or soak except the last segment that must be a soak. The difference is that the SPP Program display reads and writes a set point program from an SP programmer, and does not store the program in the server The computer on which the Experion database software and server utilities run. See also: Experion server TPS. database.

The SPP Trend A display in which changes in value over time of one or more point parameters are presented in a graphical manner. See also: display, point parameter. display allows the user to view the history of an SP programmer and compare it to the ideal profile. To collect history, a point needs to be built for each SP programmer in a controller. These points are used to monitor the process PVs driven by the primary 1. For Regulatory Control blocks in a cascade strategy: A primary is an upstream block from which an initializable input is fetched. A block has one primary for each initializable input. See also: block. 2. The controller (or chassis) that is currently controlling the redundant process by carrying out the assigned functions. Compare: secondary. See also: assigned function, chassis, controller redundancy. and auxiliary outputs of the programmers, collecting the values and storing them in history.

Building points for SPP monitoring

Quick Builder The Experion tool used to configure system components, such as standard points, Flex Stations, controllers (other than process controllers), electronic flow measurement (EFM), and printers. See also: controller, electronic flow measurement (EFM), Flex Station, process controller, standard point. can be used to build the points for monitoring the SP programmers. The points must be of 'Analog' type, and a unique point must be created for each programmer. The source addresses used to monitor SP Programmer 1 in an HC900 or UMC800 controller are described below.

Table 5-1: SP Programmer 1 Parameter Definition
Parameter Also known as point parameter. A unit of information about a point. For example, an analog point includes parameters such as process variable parameter (PV), output parameter (OP) and setpoint parameter (SP). See also: analog point, output parameter, point, process variable, setpoint parameter. Source Address

PV The process variable. An actual value in a process. In the case of an analog point, for example, the PV represents values such as temperature, flow, and pressure. A PV may also be sourced from another parameter or be calculated from two or more measured or calculated variables using a point algorithm. See also: analog point, parameter, point algorithm, PV algorithm, PV clamp, PV period.

Address the PV being driven by the output of SPP 1 in your process. See below for an example.

AL1

PV high value

AL2

PV low value

SP

SPP 1 OUT

A1

Address the PV being driven by the auxiliary output of SPP 1 in your process. See below for an example.

AL3

A1 high value

AL4

A1 low value

A2

SPP_ADD 1 AUX_OUT

A3

SPP 1 STATUS_HOLD

A4

SPP 1 STATUS_END

The point should also be configured with:

The following diagram illustrates a typical HC900/UMC800 configuration. In this example, when configuring a point in Station Experion's main operator interface. Station presents information using a series of displays. See also: display. to track programmer block A unit of data and operation within Experion. Experion uses blocks as the component from which control strategies are built. The two categories of blocks are hardware entities and functional entities. SPP3, you should configure the point's PV parameter to read the PV of loop PID2, and its A1 parameter to read the calculated PV from CARB5.

Figure 5-1: Example SPP Implementation

To monitor the other SP programmers, create a new point for each programmer and replace the '1' in the Source Address with the given programmer number (valid 1 to 4). Each point must have a unique name. Repeat this process until you have created points for each programmer. When all points have been built, download them to the server database. See the Server and Client Configuration Guide for information on points.

To configure SPP monitoring

  1. Disable the HC900 HC900 & UMC800 channels.

  2. Select ConfigureApplicationsHC900/UMC800Programmer Operation.

    The SPP Summary display opens.

  3. For each HC900 and UMC800 controller, enter each point configured for this controller in the appropriate slot.

  4. Enable the channels.

    You can verify the SPP monitoring by checking that the primary and auxiliary SP follow that of the programmers (displayed on the controller faceplate A specialized pop-up that shows a subset of the details shown on the matching point detail (or template) display. It typically shows the point's runtime values and control settings. A faceplate appears when an operator clicks an object that is linked to a point. See also: point, point detail display.).
