D400 SUBSTATION GATEWAY INSTRUCTION MANUAL
To configure a D400 to operate with a DNP3 I/O module.
1. Log in to the D400.
Result: The D400 HMI appears.
Refer to the D400 online help for detailed information on the D400 HMI.
2. Create the Device Type:
2.1. Click the Configuration
2.2. Click Client Map.
2.3. Click New to create a new device map file.
Result: The Map File window appears.
2.4. Select DNP and click OK.
2.5. In the left-hand pane, configure the device point settings.
2.6. In the right-hand pane, configure the device polling parameters.
2.7. Click Save.
3. Configure the DNP3 serial port parameters:
3.1. Click Connections.
3.2. Click Add Connection.
Result: The New Connection window appears.
3.3. Select Serial Connection and select DNP Multidrop on the Serial Configuration
Type drop-down list.
3.4. Configure the connection as required. For Map File, select the client map file
you created in Step 2.
3.5. Click Save Configuration.
Refer to Appendix B for DNP3 I/O module installation instructions.
A redundant D400 setup allows a secondary D400 to automatically take over operations
from a paired D400 unit that has failed.
D400 equipment redundancy requires two D400 units and zero, one, or two RS232 switch
panels.
The RS-232 switch panel is optional for Warm and Hot Standby redundancy.
A pair of LEDs marked CCU A and CCU B indicate which of the D400 units is currently active.
If the hardware or software of the active unit fails, it is automatically switched offline and
serial connections to the field are transferred to the standby unit. A toggle switch on the
RS232 switch panel can be used to switch the D400 devices between active and standby
modes.
If the active D400 unit fails, the following actions occur:
1. The standby D400 unit detects the failure through the lack of a heartbeat signal on the
ping cable or through a status change on the watchdog cable.
