Control Commands
A client sends control commands for most operations over the Control TCP channel (port 3190).
The Control channel and the Upgrade channel (port 3192) can be connected simultaneously. For more
information on Upgrade commands, see Upgrade Commands on page 486.
States
A Gocator system can be in one of three states: Conflict, Ready, or Running. The client sends the Start
and Stop control commands to change the system's current state to Running and Ready, respectively.
The sensor can also be configured to boot in either the Ready or Running state, by enabling or disabling
autostart, respectively, using the Set Auto Start Enabled command.
In the Ready state, a sensor can be configured. In the Running state, a sensor responds to input signals,
performs measurements, drives its outputs, and sends data messages to the client.
The state of the sensor can be retrieved using the Get States or Get System Info command.
The Conflict state indicates that a sensor has been configured with a Buddy sensor but the Buddy sensor
is not present on the network. The sensor will not accept some commands until the Set Buddy
command is used to remove the configured Buddy.
