Configuring isochronous mode on the DP slave
1. Select the DP slave in the network view and navigate to the "isochronous mode" area in
the Inspector window.
2. Enable the option for synchronization to the DP cycle for the DP slave.
Default: The DP slaves get the Ti/To values from the subnet which means the values are
automatically the same for all DP slaves of the DP master system.
3. Enable the "Isochronous mode" option the the "Detail view" for all I/O modules you want
to operate in isochronous mode.
4. Repeat steps 1 and 3 for all DP slaves that you want to operate in isochronous mode.
