<p>Maybe the file is in a similar position as CODESYS Control for Linux SL.<br/>

I have a plc Eaton XC303 with 8 HMI connected. If I want to connect just on more I can't. I have disconnect all the hmi. Under device page, shell plc, I send "channelinfo" command and the respose is:</p>
<p>CmpChannelServer channel information:<br/>
Maximum 8 channels (at timestamp 109477)<br/>
Channel 0: OPEN PROCESSING AddrPeer 30CA.C0A8.896F.800F, ChannelId 50168, ComBufferSize 95776, LastRxTime 109476, LastTxTime 109466<br/>
Channel 1: FREE <br/>
Channel 2: FREE <br/>
Channel 3: FREE <br/>
Channel 4: FREE <br/>
Channel 5: FREE <br/>
Channel 6: FREE <br/>
Channel 7: FREE </p>
<p>It is obvious that the plc can handle a maximum of 8 channels. It's a plc's limit? It's a codesys' limit? How can I find a workaround? <br/>
Thank you and sorry for my english.</p></div>
