Local Cycle Time
for Sending
Step
1
Draw up a simple table with two rows and the number of columns corresponding to the send
messages.
Mark the first row "Send" and the second row "Receive".
2
Enter in the "Send" row the transit times of all possible send messages in descending order.
3
Then enter in the "Receive" row the transit times of all possible receive messages.
If you have fewer receive than send messages, you must complete the "Receive" row,
starting with the longest receive message, until the same number of send and receive
messages has been entered.
If you have no receive messages, do not make an entry.
If you have more receive than send messages, delete all excessive receive messages
starting with the last, shortest receive message.
4
You obtain the local cycle time for sending by adding up all the message transit times in the
completed table.
