To change the Server's internal parameters, invoke the /Configure/Server Settings...
command. The "Server Settings" dialogue box will appear:
The following describes each field in this dialogue box:
Protocol Timer Tick
This field is used to change the frequency at which the Server checks for work to do. This
should be approximately 2 to 4 times the fastest rate desired to update data from the SPA
bus devices.
NetDDE being used
Select this option if you are in network using NetDDE.
Configuration File Directory
The first field is used to specify the path (disk drive and directory) in which SPA will save
its current configuration file. SPA will use this path to load the configuration file the next

Notes.
1. Only the "path" may be modified with this field. The configuration file is always named
SPA.CFG.
2. There is no limit to the number of configuration files created, although each must be in
a separate directory. When using the SPA Server with InTouch, it is a good practice
to place the configuration file in the application directory.
Retry failed write messages indefinitely
This field is used to disable the deleting of pending write messages when slow poll mode
on some topic is started. As default all write messages for this topic are deleted when
topic enters the slow poll mode.
Note. Be careful when using this setting if SPA device is switched off, but client
application continues to generate new values to be written to this device -- it can cause
the computer memory overload with memory allocated for write messages.
Start automatically as Windows NT Service
Enabling this option will cause the SPA Server “Suite Link & DDE” version to start as a
Windows NT service.
Windows NT offers the capability of running applications even when a user is not logged
on to the system. This is valuable when systems must operate in an unattended mode.
Enabling this option and rebooting the system will cause the Server to run as a Windows
