I figured there was some sort of limitation.</p>
<p>I wonder how things will be at Moeller since Eaton has purchased them?</p>

<p>I'm afraid that several instances of MBM_Communicate won't work.</p>
<p>The function block has global variables containing an array with all connections. The connections are limited to 10!</p>
<p>I suggest to contact Moeller support ( e <a class="" href="mailto:sia@moeller.net">sia@moeller.net</a> e ) May be that they can provide a modified Lib.</p>
<p>regards</p>

<p>Is it better to have 12 instances of the MBM_Communicate function block or only 1 instance where I loop through all the remote nodes?</p>
<p>The 1st option seems the better for me as it would require less code and as each of my slaves is identical, it could be encapsulated in function blocks.</p>
<p>Anyone have experience here?</p>
<p>Thanks</p></div>
