Cyclic Data Exchanges Overview
The protocol manager supports cyclic data exchanges between the controller and the slave devices.
The cyclic data exchange requests are supported by a channel for Modbus TCP.
Predefined devices have predefined data exchanges, for which the cyclic data exchanges are automatically defined. To configure the Generic devices, you must add the channel in Modbus TCP Channel Configuration.
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.
