DMEShim®

Features

DMEShim® is the mechanism that allows InspectIt! to handle inspection errors from the DME I++ server directly. It also comes in handy when a user wants to inject their own commands into the DME. Homing a machine, or clearing errors are helpful. Further if a problem is encountered with a DME command it may be translated or converted to a different format when sent from the DME client to the server.

The DMEShim's is a communication shim between two ports. The DMEShim acts as both a client and a server and is able to read errors as well as inject commands into the communication stream when needed. For instance a DME client such as eMInspector would normally communicate on the standard DME I++ Server port 1294, however setting up the DMEShim to be a server on Port 1293 and changing eMInspector's MTI port to 1293 would force the commands to go through the shim. At the same time the DMEShim(Client) would connect to the DME I++ Server and relay commands as appropriate back and forth between the DME I++ Server and the DME I++ Client.

DMEShim® Features
Version	1.0
Technology	.NET (fw1.1)
> Asynchronous communication DMEShim® uses asynchronous communication as prescribed by the DME I++ specification. Transactions are processed normally and the DMEShim is transparent to both the DME Client and Server as they are relayed through the DME Shim.
> Error trapping directly from the DME I++ Server Using InspectIt! to increase inspection integrity by handling occurrances of errors appropriately to instill assurance in the inspection results it is important to detect the errors directly from the DME I++ interface. This way both standard and extended errors can be trapped directly and immediately without reliance on a third party. When an error occurs InspectIt will be notified and will react to the errors appropriately.
> Inject I++ commands directly in the communication stream When the DMEShim is in place it is possible to inject I++ commands into the communication stream to take advantage of many different aspects of the I++ protocol. Further, it is possible to handle error conditions of the machine such as the I++ DME requirement for the machine to be homed prior to the start of an inspection. InspectIt! can automate this so it is seamless for the operator. What used to be an error now becomes a prompt to let the user know the machine is not homed and to select OK to home the machine when the probe is cleared to do so.
> Communication sneak a peek DMEShim has the capability visualize all communication between DME Client and Server. If errors in communication happen it will provide a method to help diagnose the problem.
> Suppress commands DMEShim has the capability to suppress or change commands between client and server. In a dire straight this gives a capability of quick response to support issues that may happen in a production environment; better safe than sorry!
> Documentation, Tutorials  Documentation and self help tutorial will be provided.
