I think implementing their software option A seems like a reasonable thing to implement in the code, although as they noted the polarity switch is under the purview of the MPS controller. Basically if the current is above a small amount e.g. 5-10 A the PLC
will ignore any value change of a different polarity. <span style="background-color:rgb(255, 255, 255);display:inline !important" class="ContentPasted0">I'll work with Aaron to get that added.</span></div>

Eugene has also suggested disabling the remote functionality completely and only switching polarity manually.</div>
