Cyclic Data Exchanges Overview
The protocol manager supports cyclic data exchanges (implicit messaging) between the controller and the slave devices.
The cyclic data exchange requests are supported by a connection for EtherNet/IP.
Predefined devices have predefined data exchanges, for which the cyclic data exchanges are automatically defined. Devices with an EDS file have predefined connections—you must select the connection or channel to use with your application.
If necessary, you can configure these data exchanges using the dedicated DTM or the appropriate third-party tool. For details, refer to the documentation of the device.
You can add and configure new requests for these devices and generic slave devices.
For all data exchanges, you can map variables to be used by the program.
