    MA1059 MAQ20-DIV20/-DIVC20 Hardware User Manual Figure 3: Possible System Configurations 6.0 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 12: 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 Registration Numbers thereby making graphical representations match physical location for a single, local backbone.

    MA1059 MAQ20-DIV20/-DIVC20 Hardware User Manual there is communications activity on the TX and RX LEDs. Allow 1 second for registration. This module now has the same Registration Number as the one removed. CASE 2: I/O module is suspected faulty and is to be replaced with the same model number: Remove a single MAQ20 I/O module from any local or remote backbone position.
  • Page 14 MA1059 MAQ20-DIV20/-DIVC20 Hardware User Manual STANDARD EXPANSION PROCESS 1.) Turn system power on and observe communications activity on the I/O modules. 2.) Add a single MAQ20 I/O module in any local or remote backbone position. Observe that the green Power LED is on and communications activity is seen on the TX and RX LEDs. Allow 1 second for registration.
