Abstract
An industrial network apparatus includes: a control data communicator configured to transmit control data in a priority transmission period that occurs periodically; and a message data communicator configured to determine whether or not to start transmission of message data in a non-priority transmission period depending on a required transmission time of message data and remaining time of the non-priority transmission period that is different from the priority transmission period, and to transmit the message data when determining to start transmission of the message data.
Claims16
An industrial network apparatus comprising:
- a control data communicator configured to transmit control data in a priority transmission period that occurs periodically;
- and
- a message data communicator configured to determine whether or not to start transmission of message data in a non-priority transmission period depending on a required transmission time of message data and remaining time of the non-priority transmission period that is different from the priority transmission period, and to transmit the message data when determining to start transmission of the message data.
A data communication method comprising:
- transmitting priority data in a priority transmission period that occurs periodically;
- determining whether or not to start transmission of non-priority data in a non-priority transmission period depending on a required transmission time of non-priority data and remaining time of the non-priority transmission period that is different from the priority transmission period;
- and
- transmitting the non-priority data when determining to start transmission of the non-priority data.
An industrial network apparatus comprising:
- control data communication means for transmitting control data in a priority transmission period that occurs periodically;
- and
- message data communication means for determining whether or not to start transmission of message data in a non-priority transmission period depending on a required transmission time of message data and remaining time of the non-priority transmission period that is different from the priority transmission period, and also transmitting the message data when determining to start transmission of the message data.
