9.3 Error Messages

Overview

Sometimes errors occur while you are programming or loading a configuration into your instrument. In most cases the instrument displays a descriptive error message. For example, if you try to program a function block incorrectly, the instrument tells you the problem.

Table 9-4 lists these error messages along with a description of each one and what action to take.
