transmissionType

@ConfigurationParameter
protected int transmissionType

The transmission types for the analogue inputs are described in the following: acyclic, synchronous: The transmission is initiated if a SYNC-message has been received (PDO- transmission type 0) and data has changed. cyclic, synchronous: The transmission is initiated if a defined number of SYNC-messages have been received (PDO-transmission type 1...240). synchronous, remote request: The state of the inputs is latched with each SYNC-message and is transmitted after the reception of a RTR-frame (PDO-transmission type 252). asynchronous, remote request: After the reception of a RTR-frame the last latched state of the inputs is transmitted (PDO-transmission type 253). event controlled, asynchronous: The transmission is initiated if the state of selected inputs has changed (PDO-transmission type 254, 255).
