<div><div>Hello,</div><div><br></div><div>I have a Beckhoff EL9820 slave board and its working counter seems to have a problem. Its actual/expected working counter is 3/5. Is it a master's bug or slave configuration's fault?</div>
<div><br></div><div>I am using ec_master version 1.4.0-rc3. I burnt the sii with the default TwinCAT configuration file, which is, I believe, from C:\TwinCAT\Io\EtherCAT\Beckhoff FB1XXX.xml.</div><div><br></div><div># ethercat pdo</div>
