<div class="moz-cite-prefix">Thank you for your response. Sorry for the late response, but I was only able to try it out today because of life was so busy.<br>
<br>
You were correct - all I had to do was activate the master, and then wait a while.<br>
<br>
I looked at the dc_user example. What is registering PDOs all about? Do I just need to register one of the registers in a PDO mapping, or do I need to register all of them? I noticed that registering just one from each PDO mapping made the domain_data_size
correct. I have one PDO mapping for input and one PDO mapping for output. Should I create two different domains for each PDO mapping? Or can I use both PDO mappings with one domain?<br>
<br>
Is there an example program which involves both input and output?<br>
<br>
Is there documentation on the Ethercat User Group website that could help me sort this all out? (I have membership, so I can look at everything they have.)<br>

ask it to print out the PDO using ecrt_master_get_pdo and ecrt_master_get_pdo_entry, I get output that tells me it is using the 2nd PDO mapping (see below). I feel like I am missing something. Is there a good sample program that shows me how to set up something
like this that I can copy?<o:p></o:p></span></p>
