Problem Statement: In order to allow insertion of historical data into a repository, the past time parameter found when right clicking on the repository and clicking on Properties, has to be big enough (in hours) to go far enough back into the past to accept the data you're trying to insert. Also, the creation date of ... | Solution: At the command prompt, run the h21arcadmin utility to change the start or end time/date (whichever is applicable) of a fileset and then run the h21arcck utility, making sure you use the -x flag, to rebuild the fileset. This flag will stop the h21arcck from overriding your date change.

Problem Statement: How are the tag status values determined for SQLA tags? | Solution: The status codes are the same as those used for CIM/21. Please seeSolution #100142 for a list of these codes. Note that the number value is translated from CIM/21 usage to IP.21 usage. Therefore, when viewed in the data table in Process Explorer, you will see a different numeric value for the status that what... |
Problem Statement: Somewhere, such as inside a field in an Aspen InfoPlus.21(IP.21) record, or maybe in a .OUT file relating to an application, you might see the generic error message :
Data changed but no history generated (bad key time stamp) | Solution: The exact meaning of this error is that there was an attempt to write data into IP.21 history, but the timestamp associated with the value being written is older than what is allowed to be entered into the InfoPlus.21 History repository.
The mechanism for determining just how old data can be begins with openi... |
Problem Statement: How to load a list of calculations into AspenCalc without using the AspenTech's AspenCalc GUI program?
How to load calculations from a XML file into AspenTech's AspenCalc? | Solution: You can take advantage of the Aspen Calc GUI function to accomplish this.

Problem Statement: When the Windows system clock is set to the wrong time, various problems can occur if Aspen InfoPlus.21 generates a timestamp or invokes scheduled activations. This article describes how to change the default threshold Aspen InfoPlus.21 uses to check for unusual changes in the Windows system time. | Solution: Aspen InfoPlus.21 has been enhanced to periodically check for significant unusual changes in the Windows system time. Aspen InfoPlus.21 will lock the database if the Windows system time has changed too much. (The default threshold is one year.) Aspen InfoPlus.21 will resume after you have confirmed that the c... |
Problem Statement: This knowledge base article states AspenTech's position in regards to using the Aspen Manufacturing Suite on a server with a 64-bit processor. | Solution: Prior to V7.2 the Aspen Manufacturing Suite products have not been modified to take specific advantage of 64-bit processing. AspenTech has never tested installations of those earlier Aspen InfoPlus.21 versions on 64-bit processor machines therefore we can't say we support it even though it would most likely w... |
Problem Statement: Transition Manager entry stuck indefinitely after clicking on the Run and the Stop button. | Solution: The problem here is that when Transition Manager is being stopped before completing its processing, it will crash and get stuck in an indefinite loop. This is a known bug and it is fixed in ER # PM010220A.NTI (Solution ID #105145). This ER fixes various problems with Aspen Process Recipe and Transition Manage... |
Problem Statement: The setting selected in the IP_VALUE_FORMAT field of an IP_AnalogDef record dictates how the IP_VALUE field, and other floating point fields in that record, are displayed in InfoPlus.21. If numbers are not displaying as expected, you will need to verify the correct format was selected. The following | Solution: explains how the IP_VALUE_FORMAT sets the format of an analog point.
Solution
Analog data points are formatted by a floating-point value format. An example of an IP_VALUE_FORMAT field for an analog value is F9.3. F9.3 is itself a special type of record in the database known as a format record.

Problem Statement: Client tools are unable to see data in some history file sets. It is possible that different client tools may not display data for different time spans. For example, Process Explorer may see data from one file set while SQLplus sees data from the subsequent file set. | Solution: The end time of one archive file set may be set exactly the same as the start time of the following file set. As a result, client tools are unable to display data from both file sets.
To resolve the problem, use the h21arcadmin tool to modify the second file set so that its start time is one second after the ... |
Problem Statement: On rare occasions, incomplete data is returned by a custom application reading data from the History table.

Problem Statement: When upgrading an Aspen InfoPlus.21 system from v2004.1 to v2004.2 using the Upgrade\Repair option on the Program Maintenance screen the list of products to upgrade only shows Aspen Local Security. | Solution: Rename the ..\aspentech\setup\uninstall folder and restart the installation. The folder is used by the installation of AspenTech products prior to AspenOne (v6.1 and older). In some cases this folder may contain files from a previous installation. Renaming the folder eliminates the confusion with older file v... |
Problem Statement: Can older versions of Aspen Process Explorer (6.0.1 and earlier) connect to newer versions of Aspen Infoplus.21 (2004 and later)? | Solution: The answer depends upon whether or not Aspen Web.21is involved! If Web.21 is on the same machine as InfoPlus.21, when InfoPlus.21 is upgraded version 2004 or later, the Web.21 components will also be upgraded to the same version at that time. If that is the case, when an earlier version of Process Explorer tr... |
Problem Statement: What is the meaning of ASCII conversion error (no format record available) as a value for IP_ALARM_STATE (in the fixed area of a standard IP_AnalogDef or IP_DiscreteDef record). | Solution: This error message is a result of not having a value for IP_ALARM_FORMAT. Typically, this field is blank in a new record. In the Administrator, simply select a value (e.g. IP_AlarmMessages) from the drop-down list for this field and press F5 (or Shift-F5) to refresh the screen.

Problem Statement: Aspen Calc has On-Demand shared calculation for creating calculations without storing the results in Aspen InfoPlus.21 tags. Can I use results of one On-Demand calculation in another On-Demand calculation? | Solution: Yes. You can use results of one calculation in another calculation, like a tag name.
Example:
ATCAI is an IP_Analogdef tag that is part of the AspenChem demo. Create a new On-Demand calculation named 'TestCalc1' in AspenCalc using the formula =ATCAI. So the On-Demand formula refers to the demo tag name.

Problem Statement: 1. Does an IP.21 database perform better on a single 3 GHz processor server or on a dual 1.5 GHz processor server?
2. Is IP.21 optimized for CPU hyperthreading?
3. Are there any plans to have IP.21 make use of either or both of these features in the foreseeable future? | Solution: Answer 1:
IP.21 is a system of multiple processes. Consequently, you might generally expect to see performance gains by having a second processor. Also, at least some IP.21 processes are multithreaded. Even a single-threaded, one-process application could benefit by running on a multiprocessor system since it... |
