5 APC: MaxBasic: Nov01 SimDis.dll MAXUM Performance Optimization Procedures September 13, 2005 The following performance improvements will significantly improve operation of Maxum by reducing information that is typically not used. The analyzer should be at 3.2b Patch 2, 4.0b Patch 4, 3.2b or later for these optimizations. It is recommended that you read through each of the procedures prior to implementing them. A. Procedure to Remove Excess Gating on Unused Detectors: Unused detector channels need to be turned off for the entire cycle in order to optimize system performance. (Unused channels that do not have the integration turned off can cause a significant processing load even though the information is not used.) 1) Load the method to be optimized into EZChrom on the Workstation. 2) Select the first unused detector. 3) Select (Method>>Integration Events) 4) Add an Integration Off entry with start and stop times that bracket the full cycle. (Typically 8 to Cycle End) 5) Repeat steps 2-5 for all unused detectors. 6) Go to Procedure B step 3 to optimize performance parameters prior to saving the method. B. Procedure to Turn Off EZChrom Performance Parameters:

6 EZChrom performance parameters that are not typically used can have the calculations turned off (example = theoretical plates, baseline noise etc.). This procedure will reduce SNE processing requirements at the end of each cycle. 1) Open EZChrom Instrument on the Workstation for the application being modified. 2) Import the method from the analyzer if the current method in the workstation does not match the method in the analyzer. 3) From the Menu Bar select: Method>>Advanced, then select the Column/Performance tab. 4) At the bottom of the "Advanced Method Options" window, uncheck all of the calculation methods that are checked. 5) At the bottom of the "Advanced Method Options" window, uncheck Calculate performance parameters for this channel. 6) Select the next detector channel at the top of the main screen and repeat steps 4-5 for each channel. 7) Export the method to the analyzer. (Go to Procedure C step 3 to export the method with maximum performance improvements.) 8) Save the method on the Workstation (File>>Method>>Save or Save As) 9) Repeat steps 1-8 for each Analyzer Application to be modified. Note 1: Procedure B. should not be used on analyzers with the Total Sulfur application since this application requires one of the performance parameters that would be turned off. Note 2: If performance parameters such as theoretical plates and peak asymmetry are monitored using the Maxum OPC Server the performance parameters must be left ON. C. Procedure to Minimize EZChrom Data Unpacking: The Minimum Data Procedures will reduce Syscon processing at the end of each cycle. When implemented, the analyzers will unpack only compact results into the database. (Concentration values plus peak details used by OPC) All data will still be viewable in EZChrom on a workstation when data is imported. Minimum Data Procedure using 4.1 Workstation 1) From EZChrom select (File>>Method>>Import)

7 2) Highlight the first method in the pop-up window and select Import. 3) From EZChrom select (File>>Method>>Export) 4) After the Method export window pops up, open the list box in the lower right hand corner. 5) Select Compact results only from the list box. 6) Check the Save settings box at the bottom of the window. This will cause your default method export to use the Compact results only setting by default the next time you export a method to this application. 7) Press (Export). 8) Highlight the same method imported in step 1 and press Export. 9) Repeat steps 1-8 each application. Minimum Data Procedure using 3.2b or 4.0b Workstation 1) From EZChrom select (File>>Method>>Import) 2) Highlight the first method in the pop-up window and press Import. 3) From EZChrom select (File>>Method>>Export) 4) After the Method export window pops up uncheck Create Secondary Results in the lower right hand corner. 5) Check Save settings as default at the bottom of the Method export window. This will cause the Create Secondary Results box to be unchecked by default, the next time you load a method to this Maxum application. 6) Press (Export). 7) Highlight the same method imported in step 1 and press Export. 8) Repeat steps 1-7 for each application. Note: Procedure C. should not be used on analyzers with the Total Sulfur application since this application requires one of the performance parameters that would not be unpacked to the database. D. Procedure to Minimize Unnecessary I/O: The Syscon performance can be improved by disabling scanning of analog and digital inputs that are not required. The recommendation will still leave the measurement value scanning for display purposes. AI Reduction: 1) From System Manager under the first application select (Application IO) then select (AI). 2) Uncheck the Enable box and then press the Update AI button for each of the analog inputs listed.

8 3) Repeat steps 1-2 for each application. 4) Go to the System tables and select (Sys AI). 5) Uncheck the (scanenable) column (0 for all entries). 6) Go back to the first application and select (Application IO) 7) Check the Enable box and then press the Update AI button for each of the analog inputs required by the application. (Typical analog inputs left on are component data from continuous analyzers as well as the Measurement values for temperature and pressure controllers.) 8) Repeat step 7 for all applications. DI Reduction: 1) From System Manager under the first application select (Application IO) then select (DI). 2) Uncheck the Enable box and then press the Update DI for each of the digital inputs listed. 3) Repeat steps 1-2 for each application. 4) Go to the System tables and select (Sys DI). 5) Uncheck the (scanenable) column (0 for all entries). 6) Go back to the first application and select (Application IO) 7) Check the Enable box and then press the Update DI button for each of the digital inputs required by the application. 8) Repeat step 7 for all applications.
