CONFIGURING SINGLE AND REDUNDANT D.20 RIOS
CHAPTER 6: USING THE D.20 RIO
Configuring Single and Redundant D.20 RIOs
A single D.20 RIO can be connected in a Terminated or Looped connection with
peripherals, while two D.20 RIOs can be connected in Redundant Links or Redundant Loop
connection with peripherals.
Single D.20 RIO
To connect to a single D.20 RIO:
1.
Complete the D.20 RIO initialization procedure: See “Initialization procedure” on
page 37.
2.
Configure the D.20 Peripheral Client from the D.20 RIO HMI by selecting redundancy
mode
Single Device
and committing the changes. Refer to the online help for further
details.
3.
Connect to the D400 HMI and execute the following steps.
3.1.
Go to the
Connection Configuration
screen, add Network connections and
select
D.20 Network Clients
from the drop down menu.
3.2.
Add the D.20 RIO device and click the
Retrieve D.20 RIO Configuration
tab.
To ensure that the service starts automatically, select the
Block Settings
>
Auto-start
option, and select
Enable on Startup
in the D.20 RIO device list table
for each device you add to the D400
3.3.
Enter the IP address, User Name and Password of the D.20 RIO and click
Download
. The default protocol is HTTP for retrieving the D.20 RIO
configuration; however if the user configures HTTPS in the D.20 RIO then the
protocol for retrieving the D.20 RIO configuration should be HTTPS.
3.4.
If the error message:
Max users logged in for user
appears in the D400 HMI,
close all open D.20 RIO HMI sessions and try to download the D.20 RIO
configuration again using
Retrieve D.20 RIO Configuration
tab of D400.
3.5.
Save and commit the configuration in the D400 HMI.
Redundant D.20 RIOs
To connect to a redundant D.20 RIOs:
1.
Complete the D.20 RIO initialization procedure in both D.20 RIOs: See “Initialization
procedure” on page 37.
2.
Designate one of the D.20 RIOs as the primary D.20 RIO and designate the other D.20
RIO as the secondary D.20 RIO. Further configuration is now done in the primary D.20
RIO
3.
In the primary D.20 RIO, configure the D.20 peripheral client from the D.20 RIO HMI by
selecting the redundancy mode as either
Redundant Loop
or
Redundant Links
and
commit the changes. Refer to the online help for further details.
3.1.
Provide the primary D.20 RIO IP address for IP Address
3.2.
Provide the secondary D.20 RIO IP address for Redundant RIO IP Address
NOTE
The applications on the secondary D.20 RIO would be stopped automatically while
performing the commit operation on the primary D.20 RIO. It may take up to 3 minutes
for the D.20 RIO to complete its commit operation. Wait this 3 minute period before
attempting the next step of the D400 configuration. If the error message “The D.20 RIO
server is not ready” appears, reboot the Primary D.20 RIO and then continue with
step 4.
