Introduction

VM3 is the third version of the "View Memory" utility written for MEI motion controllers; earlier versions (VM and VM2) worked with DSP-series controllers. The VM3 utility allows you to view and alter data stored in memory on the XMP-series controller card. This includes data inside and outside the SHARC DSP processor. When using VM3 to alter data on motion controllers, exercise extreme caution at all times:

DANGER! Changes made to memory take effect immediately, including data designed for motion components such as motors and encoders. Verify that personnel are clear of the movement zone and equipment is safeguarded BEFORE making any changes to memory data. Always operate equipment with an emergency off switch (EMO) at the ready, especially when writing and testing new software configurations.
