<div class="markdown_content"><p>Try moving your ECAT processing block onto high priority interrupt? For example in ABB AC500, "Ext CouplerX Hi Priority" would process ECAT blocks at every frame.</p></div>

<div class="markdown_content"><p>hello, all</p> <p>I am facing a problem in v3.5, there is a motor driver connect via EtherCAT slave, and one remote plc via Modbus TCP Slave.<br/> the EtherCAT is for driving the motor, and Modbus TCP is only I/O exchanging with CoDeSys v3.5.<br/> problem is:<br/> The motor was not running smoothly enough(rotating fastly or reversely suddenly), it seems motor was lost some pulses/step sometimes, if I delete the Modbus TCP slave, motor was runing perfectly, EtherCAT seems was affected by Modbus TCP, when I changed Modbus TCP polling cycle time, motor running better.</p> <p>can any one gives any tips? I really need some help from you guys now. </p> <p>thanks a lot.</p></div>
