When the motor controller is powered down it returns something that the xcuActor does not recognize. We need to parse and handle it.</p> <p>ics_xcuActor 1.5.1, FWIW.</p> <p>To wit:</p> <blockquote> <p>pfs@bee-r1:~$ oneCmd.py xcu_r1 --level=d motors status<br/> xcu_r1 d text="sending '~@,T2500,/1aM1R'"<br/> xcu_r1 d text="received '0011074006570014036'"<br/> xcu_r1 f text="command failed: RuntimeError('command response header is wrong: 0011074006570014036',) at /home/hostpfs/mhs/products/Linux64/ics_xcuActor/1.5.1/python/xcuActor/Controllers/PCM.py:96"</p></blockquote> INSTRM-67

Not detecting powered-down motor controller from PCM RS-485 traffic.

No matter which motor command was sent, the powered-down "controller" always responded with '\0`0', which is the response from a successful motor controller command.</p> <p>The suspicion is that the PCM (behind which the motor controller RS-485 bus lies) is returning the last response from the device. With that in mind I associated the ics_xcu_pcm component and am passing the ticket to Steve H.</p> <p><a href="https://pfspipe.ipmu.jp/jira/browse/INSTRM-88" title="PCM returns last response to command sent to unavailable RS485 device" class="issue-link" data-issue-key="INSTRM-88"><del>INSTRM-88</del></a> will fix this.</p> <p>Not an XCU issue; fixed by <a href="https://pfspipe.ipmu.jp/jira/browse/INSTRM-88" title="PCM returns last response to command sent to unavailable RS485 device" class="issue-link" data-issue-key="INSTRM-88"><del>INSTRM-88</del></a></p> Relates INSTRM-88 Development Rank 0|ii01hr:
