FAQ00166 of Programmable Terminals FAQ

This message indicates that the Programmable Terminal is not communicating with the host. To start communications, the Programmable Terminal's communications settings must match the Programmable Controller's settings.

The communications protocol can be set to Host Link, 1:1 NT Link, or 1:N NT Link with the communications settings in the Memory Switch Menu of the System Menu's Maintenance Mode Menu.

The communications settings in the Programmable Controller depend on the model of Programmable Controller being used. For details, refer to the Programmable Controller's operation manual.
