Protocol Timer Tick
The Protocol Timer Tick is the time interval (in milliseconds) at which protocol is executed; the frequency at which the Server checks for work to do. A good analogy might be that the protocol timer tick serves as a metronome or heartbeat to the Server. Every tick, the Server executes a function, whether it is to listen at a particular port or to send a message to a device. The default is 65 milliseconds. At values below this level, the Server may query devices too quickly for the devices to consistently answer correctly.
The Protocol Timer Tick is the resolution of the scan interval – increasing this value slows down the Server but may improve communication reliability. Decreasing this value reduces communication reliability but may slightly speed up
NOTE: 10 msec is the minimum value for this setting.
