    MA1063 MAQ20-DORLY20 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 11: 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.

    MA1063 MAQ20-DORLY20 Hardware User Manual 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. Replace the module with another of the same model number. This module can be installed in any vacant local or remote backbone position.
  • Page 13 MA1063 MAQ20-DORLY20 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.
