# Controlling an SP programmer

Considerations:

- You can change the present segments while the program is in operation. You must first place the programmer in the Hold state, then you may alter the Start Value/Soak Value or Rate/Soak Time. You must then select the Start action for the program to continue.

- Not all commands are valid in all programmer states. For example, Clear is not valid when the programmer is in Run. You must also go to the Hold state first before Advance or Reset. You can only start the program in the Ready state Commands can also be issued from the SPP Setpoint in percent. See also: setpoint parameter. 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. page.

## To control an SP programmer

1. In Station Experion's main operator interface. Station presents information using a series of displays. See also: display. select Configure>Applications>HC900/UMC800>Programmer Operation.

   The SPP Summary display opens.

2. Select a 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. in the combo box.

   The display updates with the current state of 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 configured.

3. Select the programmer that you want to control. Click on programmer's number to load the SPP Program page with its configuration. This is as shown below.
4. Click Command Programmer. The Select Action dialog box appears. Select the required action and click OK.
5. A confirmation dialog box appears. Click OK to accept the action or Cancel to remove the dialog box.

   If the command is successful, the message 'Command sent.' appears and the SP programmer status changes to reflect the command. Otherwise 'Failed to send command.' appears. See the topic titled 'Troubleshooting recipe support' for possible fail reasons.

   While the program is running, the present segment number is highlighted and the segment and elapsed timers are active. When in Hold, the segment timer stops but the elapsed timer continues.

   Click the Trend icon at the top right of the SPP Program display to access the SPP Trend display. If a profile has been downloaded to the programmer, an SP pre-plot for 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. programmer output appears. The time of the program is spread over a single screen for this plot in hours or minutes, depending on the time units. Alternatively, you can also select the Auxiliary output plot (if configured).

   You can operate the programmer using the Command Programmer button as described for the SPP Program display. The status information includes the event LEDs that are red when the event is ON.

   When the program is in Hold, the 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. plotting stops. The PV continues plotting when the program is restarted.
