Problem Statement: Is it possible to configure a calculation to automatically switch the Cim-IO server which the controller is communicating with in case this Cim-IO server goes down and there is redundant server?
Can a controller take advantage of redundant Cim-IO servers? | Solution: It is not possible to modify automatically the IO Source, not even by using calculations. Calculations per se only modify variables attributes such as setpoints, limits, etc. In case the Cim-IO server fails, the only way to switch the IO source is to to manually modify IO source in the ccf and then reload th... |

Problem Statement: AWMakeVec is a SQL function that can be used to extract Vector files. This Function can be used in the demo Query CreateVectores.sql located in:
C:\ProgramData\AspenTech\APC\Performance Monitor\etc\sql\Demo.
However, The AWMakeVec file has a limitation of 60000 Datapoints. | Solution: This 60000 Datapoints was frame due to memory consumption. In most of the cases this limitation should not represent a problem for creating the Vec. Files.
However, If it is required to extract more Datapoints an update of the existing record has to be done. Please find attached to this solution two files: an... |

Problem Statement: A typical redundant Cim-IO configuration consists of two separate Cim-IO servers. TSK_DETECT runs on the InfoPlus.21 server (which is also the Cim-IO client), and when it detects that the primary Cim-IO server is no longer communicating successfully it immediately changes over to the redundant Cim-IO... | Solution: Yes, that is a supported configuration, and it provides a way to take advantage of Cim-IO redundancy even when you have the "standard" minimum configuration of an InfoPlus.21 server and one external Cim-IO box. Keep in mind that for Cim-IO Redundancy it is recommended that both Cim-IO servers be the same (rec... |

Problem Statement: Two coefficients in the Gulf Coast sample model have the wrong sign convention and should be updated. | Solution: It was found that the coefficients for the feed rate FDR effect on both the Burning Air and Regen Temperature have the wrong signs in the SCCU submodel of the Gulf Coast sample model.
Attached is a model with the corrected coefficients. This model is compatible with PIMS versions 8.1 and higher. If you ar... |
Problem Statement: I have both fixed utilities which always remain the same and variable utilities which change with feed rate. How can I model fixed utility consumption in a submodel? | Solution: KB #129184 describes how to model fixed utility consumption using Fixed column activity approach. In this case if there is a need to shut down the unit user cannot fix the unit capacity to 0 as that will not shut down the fixed utility consumption. The only way to properly shut down the unit is to use DISABLE... |

Problem Statement: When I copy and paste a process flowsheet with several streams and unit operations it results in different energy values for the output streams. This occurs for a stream where an assay is attached with the input stream. | Solution: To understand the solutions to this discrepancy in HYSYS Refsys let us consider two streams. Consider a case where streams 1 and 2 both use the Peng-Robinson fluid package and have the same components, but stream 2 has a petroleum assay attached to it. Under identical flash conditions the results would be dif... |

Problem Statement: How can I specify the number of shell cans? or How to control the rolling capacity? | Solution: If the shell is long, it will usually be made up of several rolled steel shell cans. Customer standard lengths are determined by the rolling capacity, so anything longer than this standard needs to be made up of 2, 3 or sometimes 4 shell cans.
The rolling capacity varies across manufacturers
