<div class="markdown_content"><p>Hello, I tried cansend can0 123#12 again. I have an o-scope attached to the TX pin, and see a flatline.<br/> Does not appear to record any packets transmitted either, so must be a problem with this cape (which has very limited and old documentation)</p> <p><img alt="IMG: can quelen.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4163"/></p> <p><img alt="IMG: no luck.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4162"/></p></div>

<div class="markdown_content"><p>Thank you, I have completed those steps, here are the results;<br/> When I put the wrong NodeID (intentionally) it gives the error wrong NodeID, which tells me CANopen messages are being sent. With the right NodeID, I get a SDO Read error. Below are my Slave devices SDOs, I do not see object 16#1000:16#00 mapped.</p> <p><img alt="IMG: debug3.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4142"/></p> <p><img alt="IMG: SDOs 2.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4139"/></p> <p><img alt="IMG: cansend.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4136"/></p></div>

<div class="markdown_content"><p>Has anyone been able to get the WaveShare RS485/CAN Cape to work? I followed Edwins BB setup instructions, by: <br/> 1. Installing the RT kernel (4.18.16-bone-rt-r15)<br/> 2. Enabling the cape id BB-CAN1 in the /boot/uEnv.txt file. (Is this the right name for this cape?)<br/> 3. Editing /etc/init.d/cpufrequtils Governor to "performance"</p> <p>I checked the salve device's baud rate (125kB) and device ID's are correct (id1). If I right-click on the CANopen Manager and scan for devices, it locks up Codesys.</p> <p>CANbus is green, but the CANopen Manager never starts and stays orange. Device is always red. </p> <p>On the device (WAGO 750-347 coupler) If I unplug the slave's cable I get the expected TX/RX error lights, but otherwise if I reboot slave after master is running, the RUN light blinks green slowly indicating pre-operational state. I believe it is seeing CAN messages otherwise it would not be in pre-operational state.</p> <p>Any ideas what I'm doing wrong?</p> <p>Here is a screenshot.</p> <p><img alt="IMG: fail.jpeg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4132"/></p></div>
