Hard Configuration
Performing a Hard Configuration reconfigures the internal QCPort scan list to match all
physically connected devices on CHA and CHB. It generates the Modbus IO register
mappings that contain the input/output information for these connected devices. In
addition, the QCPort device parameters for all devices on QCPort CHA and CHB are set
to “factory default.”
Hard Configuration:
•
Sets all QCPort device parameters to their “factory default” settings
•
Erases the old QCPort scan list and creates a new scan list
•
Erases the old Modbus IO register mappings and creates new Modbus IO register
mappings
Warning
If any connected device has been custom configured, a Hard Configuration will
return the device’s parameters to “factory default”.
Hard Configuration Procedure
1. Set each QCPort device to a unique non-zero Group ID (per QCPort channel) using
the manual Group ID switches. To set the Group ID to an extended address greater
than the setting on the switch, use CH Studio.
2. If Channel B is being used, apply power to that channel so that the devices on
Channel B are active when the configuration takes place.
3. Using a pointed tool (such as a ball point pen), lightly press the Auto Configuration
button
while applying power to CHA and the D77D-EMA
. You must hold the AC
button during the power-up for a minimum of 5 seconds to begin the Auto Configure
process. During this time, the D77D-EMA Status LED will be solid green. Once it is
viewed that the Status LEDs on the QCPort devices change from fast flashing to a
slow flash (mostly off), the AC button can be released.
