SCP Instance Options

SCP launch options include Fast Load, Local Checkpoint, and Show Windows, and Logging.

Default Settings

The default settings for the four launch options are as follows:

The default settings will start an SCP instance identically to a real CP; it takes about four minutes for the SCP to start all peer-to-peer, or Object Manager (OM), connections that are found are connected. Restarting the SCP will restore the checkpoint file from the CP host (not a local copy). Use the default settings when building a new control system.

Fast Load

The Fast Load (FastLoad) option is enabled by the slider on the SCP Launcher. When the word "ON" is visible the option is enabled. The image below shows the Fast Load option enabled.

When Fast Load is ON the following occurs:

• The SCP application starts more quickly by skipping the OM peer-to-peer reconnect process

• If peer-to-peer is required, run the SCP Reset OM Tool (Start > SIMSCI > SCP > SCP Reset OM Tool) or re-checkpoint each SCP through the configurator when all SCPs are online. The executable is located in "C:\Program Files (x86)\SIMSCI\SCP\SCP Reset OM Tool".

When Fast Load is OFF the following occurs:

• The SCP application starts more slowly because the OM peer-to-peer reconnect process occurs

Local Checkpoint

The Local Checkpoint (Local Chkpnt) option is enabled by the slider on the SCP Launcher. When the word "ON" is visible the option is enabled. The image below shows the Local Checkpoint option enabled.

When Local Checkpoint is ON the following occurs:

• The SCP application starts more quickly by using the local checkpoint file and not the remote checkpoint from the remote CP Host machine.

• A local checkpoint file will be saved on the SCP machine under "C:\Users\<User>\Documents\SimSci\SCP\<CPName>\DBFC<CPName>.UC"

When Local Checkpoint is OFF the following occurs:

• The SCP application starts more slowly by loading the remote checkpoint file from the remote CP Host machine across the MESH network. The local checkpoint file is deleted.

Show Windows

The Show Windows option determines whether or not an SCP App console window is visible to the user when the SCP App is started. The Show Windows feature is disabled by clicking on the settings icon and deselecting "Show Windows". The image below shows the Show Windows option is disabled. To change the visibility of an SCP App that is already running, you must shutdown the SCP App, change the Show Window setting, and restart the SCP App.

When Show Windows is ON the following occurs:

• The SCP application console window will appear on the task bar when launched.

When Show Windows is OFF the following occurs:

• The SCP application will not console window appear on the task bar when launched.

Changing the state of Show Windows will have no effect on SCP Apps already launched.

Logging

The Logging feature is enabled by clicking on the settings icon and selecting "Logging". The image below shows the Logging option is enabled.

When Logging feature is ON the following occurs:

• Logs critical details to the startup window and to a file

• May significantly degrade performance

• Should be used for debugging purposes only
