The Component Rundown list shows one (1) day less than the campaign duration. For instance, if the campaign is 7 days long, the rundown list shows only 6 days. | Solution: This is a bug caused by Daylight Savings time. This causes MBO to incorrectly calculate the days to show for the Component Rundowns (see the purpose of this, below).

Problem Statement: How does Orion XT update events in a multi-user environment? | Solution: Here is a summary of some different situations:
Basis:
User 1 - is working in the 1st 5 days
User 2 - is working in day 6 and beyond (and includes days 1 to 5)
User 1 and User 2 are working in the same case
Situation # 1:
User 2 updates some events and does not save.
User 1 updates different events and then... |
Problem Statement: Is it possible to disable a tank in Aspen Orion XT? | Solution: A tank cannot be disabled directly in Aspen Orion XT. However, Aspen Orion XT has the capability to assign service to a tank (Material service Event ) and one could assign a tank service to be out of service. This would not, however, prevent the tank from showing up on a drop down list on an event dialog, for... |
Problem Statement: While using Aspen Orion XT 2006.5 to open a model made with Aspen Orion XT 2006 or earlier, you may see the following warning message. | Solution: This warning message indicates that you should use the Normalized Event Table option and your model requires upgrading.
Step 1: If you want to retain the existing un-normalized event table, then open Config table in the Orion Model, and add the following record as suggested in the message.
Step 2: Now save ... |
Problem Statement: When in a Trend Limit Dialog Box for a given Event Screen, if the user sets a trend limit for a tank that is not shown in this dialog box, then the trend limits that come up are not the ones for the tank specified, but for the first tank in the dialog box. Why? | Solution: Essentially there are 3 sources of the trend limit, table TREND_LIMIT, TREND_SCREEN and TANKS and the pecking order is as listed. When you change an existing trend variable to another tank that isn't already on the trend list for that screen then the new tank assumes the trend limits of the original tank rath... |
Problem Statement: Orion/SBO crashes for Gasoline blending Event Screen after apply Optimize button. | Solution: The problem here is that the number of specifications in the blend exceeded 50 which is the hard limit for the blends.
In v7.2 the following error message was added when this happen:
"The maximum number of specs for a blend is 50. Minimum specs of 0.0 and maximum specs of EMPTY are ignored and thus not counte... |
Problem Statement: In my database I have a custom table. It is possible to link this table to Aspen Aspen Orion XT so that the information can be updated by the model administrator directly from Aspen Orion XT? | Solution: The custom table can be added to the database table tree in Aspen Orion XT by adding a record in the MODEL_TABLES table. This would allow the administrator to modify the table directly from Orion. If the category for the table is set to ADMIN in MODEL_TABLES then only someone in the ADMIN group may see this b... |
Problem Statement: It is possible to specify a timeout on the adapter requests when using web services? E.g. when the Aspen Orion scheduler hits import inventories and qualities can they specify in a config file somewhere how long it will wait? If not what is the current timeout? | Solution: There is a timeout setting which can be specified for every request service. Select the Request Services folder | Request_Supply_Demand - Request Tab, then change the timeout.

Problem Statement: Users may see the warning message "ADAPTER INITIALIZATION FAILED" when trying to import Events into Orion (Integration| Import Events) even if they are NOT using the adapters. | Solution: This can happen if during the Orion installation procedure, the adapter components option was selected by error. To fix this problem follow up these steps:
1. In CONFIG table, verify/add the register called "CHECK_OMII_REGISTRY" with value = 'N'
2. Remove/delete from the following:
2.1.- C:\WINNT\Assembly... |
Problem Statement: Is it possible to display Crude Properties other than API and SUL in the standard "Crude Yields and Properties" Dialog Box? (via "Events", "Show Crude Yields" in the Menu Bar) | Solution: The answer is yes. Additional Crude Properties may be defined in data table CRUDES. The following procedure will illustrate how to accomplish this.
1.-Open table CRDPROPS :
2.-Add the property that you want to have ( CRDID (name of the crude), PROPID (CRD), PROPID (name of property, check that it already ex... |
Problem Statement: It would be very helpful if the Scheduler had another way to quickly detect problems like overage and shortages in addition to the red /green dots (points at which bounds have not been maintained) shown on the Trend Screens (Gantt interface). | Solution: Aspen Orion XT has a feature called "Inventory Problems" that allows you to display inventory problems caused by events in your schedule.
To access the "Inventory Problems" dialog box do the following:

Problem Statement: When importing a PIMS Unit Operation Event to ORION using PIMS to Orion interface, the PIMS event won't delete preview event and will display duplicate event on screen.(Ex. VDU has 09/01 to 10/15 and import PIMS event for VDU from 10/01 to 10/30, after, go to VDU event screen and check. The VDU event... | Solution: PIMS to Orion interface will only delete an existing (previous) Orion event if the Orion event start and stop exactly matches the imported PIMS event start and stop.
For more information about PIMS-Orion interface, there is a full help file called ORIONPIMSInt.chm. This file should be in the same location as ... |
Problem Statement: The IsConnected property returns true in ACM when a port of a submodel is linked. If the model is exported, the property IsConnected returns false in Aspen Plus. This is causing some problem in ACM below v7.1. The problem does not occur in ACM v7.1 and higher
We have the following:
model acm_noop
i... | Solution: This was a deficiency of the IsConnected property in ACM older than v7.1. This is not a problem with v7.1 and higher versions.
The attached file shows the expected behaviour as per design.
The rest of this section applies only to versions older than v7.1, which are no longer supported. This is only for hist... |
Problem Statement: This knowledge base article describes the possible causes for the following error message which can be logged in the cimio_msg.log file.
CIMIO_SOCK_GETSERV_FAIL, Error looking up service name WNT Error=11004 The requested name is valid and was found in the database, but it does not have the correct ... | Solution: This error message usually indicates that there is a problem with the entries in the services file. The services file is located in the following folder:
WINDOWS\system32\drivers\etc
Ensure that the services listed in your services file match the entries in your cimio_logical_devices.def file.

Problem Statement: Where are my Aspen PIMS Family Sample Models? | Solution: In the 2006.5 release of Aspen PIMS (version 17.5), the location of the Aspen PIMS Family Model templates has been moved from
<Program Installation Directory>\Aspentech\Templates\<Application Name>\<Files>
to
C:\Documents and Settings\All Users\Shared Documents\AspenTech\<Application Name>\<Files>

Problem Statement: How do I calculate the activity coefficient for a stream in Aspen HYSYS through automation? | Solution: Currently, there is not a direct way to get the NRTL activity coefficient from Aspen HYSYS. Although Aspen HYSYS internally calculates them, it is not exposed to user interface. It is planned to be available in the future release.
In attached file, MS excel macro is written to obtain the BIPs' value for all c... |
Problem Statement: The purpose of this solution is to provide more information about various XNLP/XSLP settings and highlight which settings are most important.
There are many settings related to the nonlinear model building (XNLP) and solving (XSLP) in PIMS. Whatever the setting is, our goal is to come up with a def... | Solution: XNLP Settings
XNLP Settings are the settings used when generating the nonlinear model formulation as described in the XMPS.mps file. Remember that the model is separate from the solver in PIMS-AO (Advanced Optimization).
