Perform Jogging by WebSockets

tlt

Hello,

I try to do http://localhost/rw/motionsystem?action=jog and get following message:

<span class="code">-1073436652</span>

<span class="msg">rws_resource_motionsystem.cpp[405] Change count mismatch code:-1073436652 icode:-1073436652</span>

Robot error list:

<li class="err-desc-li" title="-1073436652">

<span class="name">SYS_CTRL_E_HPJ_CHANGE_COUNT_MISMATCH</span>

<span class="code">-1073436652</span>

<span class="severity">Error</span>

<span class="description">Change count mismatch.</span>

Could you clarify what does Change count mismatch mean?

"change_count = counter to keep count for every change in the motion system(domain)"


We need to find the correct change count which we need to send to the controller with the jog request.


So first we GET this resource: http://localhost/rw/motionsystem?resource=change-count


This will return a <span class="change-count">0</span> which is the value we use in the jog request.
