Troubleshooting recipe support

This section describes cross checks and remedies to perform if HC900 Hybrid controller./UMC800 SPP Setpoint in percent. See also: setpoint parameter. and Recipe Support does not respond as anticipated.

Behavior Things to try or confirm

Cannot use Station Experion's main operator interface. Station presents information using a series of displays. See also: display. to control an HC900 or UMC800. The commands appear to have no effect.

  • Ensure that the application has been installed correctly and that all prerequisites have been met.

  • Make sure the UMC800SP.exe task is running.

Downloading/uploading a stored recipe or 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. profile fails and causes an alarm An indication (visual and/or audible) that alerts an operator at a Station of an abnormal or critical condition. Each alarm has a type and a priority. Alarms can be assigned either to individual points or for system-wide conditions, such as a controller communications failure. Alarms can be viewed on a Station display and included in reports. Experion classifies alarms into the following types: - PV Limit - Unreasonable High and Unreasonable Low - Control Failure - External Change. to be raised in Station.

The 'Clone a Profile' dialog box does not let me select the correct profile.

  • Check that each profile has a unique name. If this is not the case, then the dialog box will only select the first profile and clone this one.

Cannot enter a point name on the SPP Summary page.

Downloading a program from the SPP Program page fails and causes an alarm to be raised in Station.

The command issued to an SPP programmer appears to have no effect.

  • Some actions require the SP programmer to be in a certain state, for example, 'Clear' is not valid when the programmer is in 'Run.'

The 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. does not display the program history or the ideal profile.

The program history does not look like the ideal profile.

  • An 'Advance' command causes the programmer to advance to the next segment. This causes a 'gap' in the history values and results in the running program to be 'distorted.'

The trend draws fewer segments than in the SP program.

  • The end of the program is taken as the first segment with a length/rate of zero Ensure that your program only contains these types of segments at the end of the program. To check this, you can upload the program in the SPP Program page.

  • Check the server log for error messages.
