== Problem ==
A common issue on any machine controlled by a Nextmove Controller is a loss of the communication channel between front-end (The winMulti program) and back-end (the nextmove controller). The fault symptoms are an error message box on the front screen that can often look a bit technical:<syntaxhighlight>
Fatal Error: Cannot Write fParameter data. Device Driver Failed

Fatal Error: Cannot read Inverter data

Fatal Error: Error Downloading Starter recipe

Cannot Read Firmware on Ethernet. Must use a setXXXLink function
</syntaxhighlight>


Often, this is an intermittent problem which makes it hard to pin-point. The only method to finding the fault is to replace or try each item in turn in the root causes until the problem stops happening.
