<p>Network variable is work on the concept udp protocol, the schneider PLC if you using without network port then network variable will not be work.</p>
<p>Serial 1(RJ45) is not a network port. is just a serial port. Is just a serial port where using RJ45 connector.</p>
<p>The most simple for two plc communication is using modbus RTU.</p>
<p>Thank you<br/>

<p>I'm trying to get some communication between two M241 to work and wonder if it's possible to use SoMachine network protocol to transfer data.</p>
<p>I'm connected via USB to the first M241 and can connect to the second PLC via SoMachine network on serial line 1. (RJ45)<br/>
I have also got HMI to work via SoMachine network. But how do I transfer some variables PLC to PLC on the same line?</p>
<p>Any pointers are very welcome!</p>
<p>Regards<br/>
Tobias</p></div>
