    MA1062 MAQ20-ISOMV/-ISOV/-ISOI Hardware User Manual 9.0 Building a System An automated I/O module registration process reduces system setup to three basic steps: STANDARD SETUP PROCESS 1.) Install a MAQ20-BKPLx backbone in a DIN rail then insert a MAQ20-COMx module in the left- most position and apply power.

  • Page 15: Maintaining A System

    The system does not identify I/O modules by physical position on a backbone, only by registration sequence. MAQ20-940 ReDAQ Shape Software for MAQ20 provided by Dataforth shows a graphical representation of a system based on registration sequence and not by physical position. Tools within the software package allow the user to reassign and save Registration Numbers thereby making graphical representations match physical location for a single, local backbone and retain permanence.
