<div class="markdown_content"><p>Apparently the master cannot be set to pre-op state.<br/> So I excluded the master, by using the ALL_EXCEPT_NMT_AND_SENDER flag;</p> <p>STATE := (Cia405.TRANSITION_STATE.ENTER_PRE_OPERATIONAL OR Cia405.TRANSITION_STATE.ALL_EXCEPT_NMT_AND_SENDER)</p> <p>Now the master stays in operational state. And all slaves go to pre-op state.<br/> This behaviour is acceptable for me (for this project).</p></div>

<div class="markdown_content"><p>In the GUI, I disbaled the CANopen Manager Autostart option. And I enable the CANopen manager from my application. <br/> With CIA405.NMT: DEVICE := MasterNodeId and STATE := Cia405.TRANSITION_STATE.START_REMOTE_NODE.<br/> That is working fine.</p> <p>Now I want to disable the CANopen manager (or go to the pre-op state). <br/> Using STATE := Cia405.TRANSITION_STATE.ENTER_PRE_OPERATIONAL, result in a ERROR = CANOPEN_EQUEST_ERROR. And the CANopen manager stays in operational state.</p> <p>Did anyone notice this behaviour too? And maybe has a solution to get the master out of operational state.</p> <p>Regards,<br/> Edwin.</p></div>
