8. In the Requested Packet Interval (RPI) field, enter the RPI for the
connection in 1 ms increments.
The default is 20 ms.
The RPI specifies the period when data updates over a connection. The
RPI of the consumed safety tag must match the safety task period of the
producing safety project.
The Connection Reaction Time Limit is the maximum age of safety
packets on the associated connection. For simple timing constraints, an
acceptable Connection Reaction Time Limit can be achieved by
adjusting the RPI.
The Max Network Delay is the maximum observed transport delay from
the time the data was produced until the time the data was received.
When online, click Reset Max to reset the Max Network Delay.
