Watchdog Tab (Administrator)
Use the Watchdog tab to configure the Host Connection Watchdog, which is used with the Safe Status settings
to define each I/O channel’s response to a lost network connection. When the ioLogik E4200 loses its network
connection for the amount of time specified in the timeout, the Host Connection Watchdog will switch the
ioLogik E4200 to Safe Status and the I/O channels will reset to their Safe Status settings. By default, the
Watchdog is disabled. To enable the Watchdog, make sure Enable Host Connection Watchdog is checked,
set the Timeout value, and then click the Update button.
After the Watchdog is enabled, the ioLogik E4200 will enter safe status if the network connection is lost. Once
the connection has been restored, you will need to return to the Watchdog Tab in order to exit safe status. You
will see a “Host Connection Lost” message indicating that the I/O device is in safe status. Click Clear Alarm to
exit safe status and return to normal operation.
Active Tags (Administrator)
Click the Active Tags tab to configure the I/O channels to report their status to a Moxa proprietary Active OPC
Server package. The Active Tags and the Moxa Active OPC Server package provide I/O status reports by event
via TCP packets. This allows the ioLogik to provide the OPC-SCADA architecture with better I/O monitoring and
control. Specify the IP address of the Active OPC Server, select the I/O channel that needs to be updated, and
then click the “Create Tag” button. The tags will be created automatically. In other words, users only need to
launch the Active OPC Server program, and the I/O channels selected by the user will be “pushed” from the
ioLogik to Active OPC Server.
1. Download Active OPC Server Lite from Moxa's website and install it.
2. Log in to the Modular ioAdmin utility and go to the Active Tags tab.
3. Specify the Active OPC Server IP Address by clicking on the IP button. After clicking OK, Modular ioAdmin
will ask you to restart the ioLogik E4200.
4. Click the Active Tags tab to specify which I/O modules and channels need to be updated.
5. After clicking the Active Tags tab, we recommend specifying the Heartbeat Interval so that the Active OPC
Server is able to detect when the ioLogik E4200 is disconnected.
6. Next, click on the Create Tags button.
7. Launch the Active OPC Server program from the PC; all of the tags will be generated automatically.
