The actual timing for data link area refreshing in this example is as follows:
• When transmitting: Data is transmitted over the network the next time that
the token right is acquired. (The transmitted data is delayed up to 1 com-
munications cycle time max.)
• When receiving: The data that is input was received from the network the
last time that the token right was acquired. (The data received is delayed
up to 1 communications cycle time max.)
Examples of Data Transfer Processing:
• Transferring Data from the Previous I/O Refreshing
