The number of bytes in/out of SST-DNET-COM software can also provide this information.
In the figure above, the input and Output 64-Bytes bytes provided under the "Polled" project are the default input
and output data byte lengths.
The maximum number of input bytes supported by SST-DNET-COM software is 128, and the maximum number
of output bytes is 112.
Take "Polled Input" and "Polled Output" as examples:
Click the "Polled Input" button, and then click the "Read" button, DeviceNet software will read the network input
data. If the user selects the "Continuous reading" check box, SST-DNET-COM software will continuously read the
network input data of the field DeviceNet device. As shown in the figure below:
Similarly, by clicking the "Polled Output" button, users can see the network output data dialog box. The user must
type in all the output data, otherwise the output data is incomplete (the number of bytes is incorrect), and the
output will not succeed.
