A communication error occurred between the client and server. Will

data collection continue?

Because data collection is performed between the server and data collection devices, the

operation continues even when a communication error occurs between the client PC and

server PC.

When a communication error occurs between the client PC and server PC, the client logs

was in progress and the project’s Keep Lock State was set to ON, the project will remain

• Ask the user who locked the project to unlock the project.

• Clear the Keep Lock state.
