Problem Statement: For a certain version of OPC server on the Honeywell AppNode (TPN Version R684.1, TPS Release 401 Version 1.3, and TPNDSS.EXE Version: 401.1.1.3.0), it has been observed that the OPC client configured in APC Builder may cause a memory leak in the TPNDSS.EXE process running on the AppNode. | Solution: The memory leak could be result of corrupted tag name cache on the OPC server. To stop the memory leak on the AppNode, disable "tag name cache" in the OPC Client configurations on the APC\online server. To change the configuration, launch Configure This Server through APC Builder, switch to the IO tab, selec... |

If this value starts counting down from 14400 then the controller has lost its license and ... |
Problem Statement: How does the DMCplus engine use the MOVRES parameter to calculate the step size for a MV? | Solution: The MOVRES parameter for an MV is used by the DMCplus engine to add a constraint on the smallest MV step that the controller can write out to the DCS. This feature is not for DCS resolution problems; rather it is for physical process limitations. MOVRES defines the smallest change (in engineering units) the c... |

Problem Statement: What does the message "Adjusted steady-state step to 10.0*(IPXNCI/300)*MAXMOVE" mean? | Solution: During the controller's validation, the maximum steady-state move (SSSTEP) of a MV has to be
0.0 < SSSTEP <= 10.0 * (IPXNCI / 30) * MAXMOV
where IPXNCI is the number of model coefficients and MAXMOV is the maximum move per cycle
Anything bigger will be reset to the mentioned high limit and a messa... |
Problem Statement: Why do the individual (Manipulated or Controlled) variable operator service switches remain ON even after the Main controller switch is OFF? | Solution: The service switch of individual Manipulated Variable or Controlled Variable is independent of the main controller Master On/Off switch. This allows the operators and engineers the option to take out only specific MVs, FFWs or CVs from the controller calculations when the controller is running in closed loop ... |
