<p style="margin-top:0;margin-bottom:0">Hello Steven,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">To summarize what we talked about this afternoon, finished today, and the plan for tomorrow:</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Today Amanda, Brian, and I updated the firmware on the HMS primary and redundant PLC from version 16.057 to version 20.058 and installed the new Ethernet (<span>1756-</span>EN2T), ControlNet (<span>1756-</span>CN2), and
Redundancy (1756-RM2) modules received last summer in both the primary and secondary controller chassis.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">To get the new redundancy modules working, we had to downgrade the firmware they came with to version 20.009. We were then able to get the HMS PLC program running and the redundancy modules synchronized. We saved the
.ACD program file as "<span>HMS_Controls_V21D.ACD</span>" in M:\dsg-hallc_controls.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Right now, even though the system is up and running, there is a red LED blinking on the new redundancy modules indicating that only one fiber cable is connected. Since the PLC system is running fine, it does not seem
like the second fiber cable is required to run. You mentioned that you would look into submitting a PR in for a second fiber cable to be able to clear the LED indicator on the modules.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Tomorrow, we will meet at 10:30AM in the counting house to test that the PLC system switches to the redundant chassis if the primary is disabled.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Best regards,</p>
<p style="margin-top:0;margin-bottom:0">Tyler<br>
