Introduction

Command Path Project, Settings...

NOTE: SysCAD must be stopped for this command to be accessed.

This command will open the Project Settings dialog box. The user may set some project, tag naming convention, historian and network options with this. The Project Settings command is not available if SysCAD is running or solving.

Modes

ProjectSettings.png


Network Solution

  • The simulation mode is displayed here as either ProBal (Steady State) or Dynamic.
  • The mode is set in the Project Configuration when the project is first created.
  • If both ProBal and Dynamic are allowed in the Project Configuration, then this field will be white and the user may change the Network solution here. Otherwise, if only one solution is allowed, then this field will be grey and the user may not change it.
  • If the simulation mode needs to be changed after the project has been created, then user must first close the project, then edit the Project settings to change the simulation mode.

Node solution

  • This field is used in the Dynamic mode. It allows the user to set the default solution for surge units.
  • The solutions that are visible in this field will be determined by the level selected in the Project Configuration. Therefore, not all of the solutions shown below may be visible.
  • All of the available solutions are:
    1. Inline - The units have surge and allow the user to implement internal level control in the unit.
    2. Direct - The units will have no surge and will behave in exactly the same fashion as a ProBal model.

Link solution

This solution is Direct and may not be changed.

Flow Calculations

  • This field is used in the Dynamic mode. It allows the user to set the default calculation method for links, or pipes.
  • The solutions that are visible in this field will be determined by the level selected in the Project Configuration. Therefore, not all of the solutions shown below may be visible.
  • All of the available solutions are:
    1. Transfer Push - See Dynamic Transfer - Transfer Push Mode for more information.
    2. Transfer Pull - See Dynamic Transfer - Transfer Pull Mode for more information.
    3. Simple - The flow is calculated based on a relative pressure network, used when absolute pressure values are not available.
    4. Linear - The flow calculation is linear.

Heat Calculations

This determines the default method used to calculate the energy balance. The three options available to the user for both ProBal and Dynamic modes, as shown in the above image, are described here:

  • None - For user wanting a mass balance only, using this option provides a faster calculation speed. However, do take note that this would result in all streams being at 25°C.
  • Reduced - SysCAD will perform an energy balance for the project. Calculations involving water and steam will use the Low Fidelity water properties (See Water and Steam Properties)
  • Rigorous - SysCAD will perform an energy balance for the project. Calculations involving water and steam will use calculations based on the IAPWS-IF97 standard (See Water and Steam Properties)

Dynamic

These two options are only available in Dynamic mode.

  1. The user may enable Synchronise with Clock by checking the tickbox.
    • This will run the simulation in real time.
    • A real time project uses the computer's clock as its time base, and is used in the historian and the trend windows.
  2. The Time input box allows the user to specify a current time. The format is: date <in number format>:time<hour:min.sec>.

Graphics and Tags

These are the defaults and rules are used when working with graphics and units.

Project Settings 2.png


Graphics Default

  1. Library - The location of the library containing any groups that the user may create or insert in the project. Please see Insert Group and Create Group.
  2. Group - The default here is Frames
  3. Page Frame - This sets the size of the markers on the graphics windows. The default is Extents-A3 (420 x 297 mm). NOTE: if user wishes to add in their own border then it is best to select the "none" option.

Tag Naming Conventions

  1. Allow Tags Beginning with Numeric - if this tickbox is enabled, then SysCAD will allow units and pipes to have tags beginning with a number. However, the tag MUST also contain at least one letter from the alphabet.
  2. Non-numeric character to insert - If the above tickbox is disabled, then SysCAD will insert this letter before a number in the case where the tag only contains numbers.
  3. Numeric Suffix Length - the numeric length used for default tags. The default is 3 - so for example pipes will be named P_001, P_002, etc.

Archive

Please see Archive Reporter.

Historian

Please see Setting up the Historian.

IO Connections

The user may set the rules for connecting to other software.

IO Marshal

  1. Enable the IO Marshal by checking the On tickbox.
  2. Browse for the marshal configuration file (.scm). If Marshal is running on a different PC (node) you will need to specify the node of the other location.
  3. SysCAD will open SysCAD Marshal and load in the IO tag data defined and report any errors. Any errors will be reported in the SysCAD Marshal program.

(Please also see SysCAD Marshal for more information on this topic)

OPC Server

  1. Enable the OPC Server by checking the On tickbox.
  2. Use as SysCAD2OPC - This allows you to run 2 copies of SysCAD both acting as differently named OPC servers. If this is disabled the normal name is SysCAD.OPC.
  3. Reset Registration - this registers the OPC server at startup.
  4. Use Aliases - Allows user to specify a list of tag aliases in a csv file. Use Browse to browse for the csv file. File is automatically reloaded after a change. Press Check Tags to check that tags in list are valid.
  5. Tag Browser Options - User can choose combinations of Tags (PlantModel, GlobalArea and any inserted unit models), $Tags ($Ctrl, $Pwr, $SDB and $Solver) and Aliases from dropdown list. This affects what items are displayed in the Browse window in the OPC Client. User can choose to have tags with or without conversions.

Alias File

Alias file contains two columns: First column is the alias used in the OPC Client, second column is the SysCAD tag. First row of text (or csv) file is ignored. The Alias must be unique (duplicates not allowed).

Two types of Aliases can be used:

  1. A full SysCAD tag can be mapped to a full Alias. Tag can optionally contain conversions.
  2. A partial SysCAD tag ending with .* wildcard can mapped to an Alias. See example below.

For example:

Alias Tag
Lvl TNK_001.Lvl
Lvl_Perc TNK_001.Lvl (%)
Pipe5 P_005.Qo.*

In this example, all P_005.Qo part tags will be available in the OPC Client as Pipe5. For example, using Pipe5.Qm (t/h) in OPC Client will map to P_005.Qo.Qm (t/h).

DDE

The user may enable a DDE link by checking the On tickbox.
