Changing Network Sample Rate

RapidCode API

How do I change the EtherCAT network sample rate? I tried just using controller->SampleRateSet(500) but it looks like I also need to recreate the ENI file? I do not see any options related to sample rate in rsiconfig so I’m not sure how to achieve this.

Hi @edco,

You want to create an ENI file with the new sample rate.

Fresh system without a network running.
Use SampleRateSet
Discover the Network.
Generate a new ENI file.
Start the network.

I believe RapidENI will generate an ENI file at the controller’s current sample rate.

The RMP sample rate is in the rsiconfig generated settings.xml, you can see it here:
