executed
Note This communications cycle time is calculated assuming that there is no node
that transmits event frames before the RECV command is sent.
The following diagram indicates the data flow which will yield the maximum
delay time from the time SEND(90) is executed by the user program to the
time the Controller Link Unit stores the data in the destination Unit’s memory.
Max. transmission delay = Link Unit servicing interval (source node) + Trans-
mission processing + Communications cycle time + Transmission delay +
Reception processing + Link Unit servicing interval (destination node).
Link Unit servicing (source node) × 2
Link service processing (source node) × 2
