If you encounter SuiteLink communication:
-
Confirm that Microsoft TCP/IP is operational on the computer on which the InTouch HMI is installed.
-
Verify the computer node name is 15 characters or fewer.
-
Confirm that SuiteLink is running as a service on the computer on which the InTouch HMI is installed.
-
SuiteLink is automatically installed during the InTouch installation. The SuiteLink service starts automatically. If the SuiteLink service stops, you must start it again.
