Global I/O not working after OnGuard server is rebooted


Global I/Os defined in the system are no longer working after the OnGuard server is rebooted.


In most cases, this issue is caused by the Linkage Server service not running, and/or not starting automatically on system boot.

To resolve this issue, follow these steps:

1) Click the Start button, then select Run. The Run dialog is displayed.

2) In the Open field, type services.msc and click [OK].

3) In the Services window, locate the LS Linkage Server service in the list. Right-click the service and select Properties.

4) In the Properties window, verify that the Service status is "Started". If not, click [Start].

5) Verify that the service has a Startup Type of "Automatic". If not, select "Automatic" from the Startup type drop-down.

6) Click [Apply], then click [OK] to save the changes.

After the LS Linkage Server service is started, global I/Os should be functional. Selecting a Startup Type of "Automatic" will ensure the service starts the next time the system reboots.
