Symptoms:

When you try to download a strategy, you receive an Undefined Command error. The Undefined Command error message displays the last command sent and the response to the command. The last command sent may vary. The response to command is: "-1.#INF definition unknown".

This error may occur when an analog point has been scaled with a Lower Actual Scale value that is equal to the Upper Actual Scale value.
