Priority Control for Urgent Commands (Patented)
As Modbus networks increase in size and complexity, the lag time
between commands and responses becomes a major concern.
Advanced models of the MB3000 series provide a priority control
function for urgent commands, allowing users to force certain
commands to get an immediate response. Depending on your
system’s requirements, different methods are available to define which
commands receive priority.
