- Page 10 Introduction Extended Operation In extended operation, you can use the complete range of functions as described in the AS-i master specification. This type of operation is supported by a function (FC) that is supplied on a diskette with this manual. In extended operation using the FC, you can also implement master calls in the user program.
- Page 11 Introduction Operator Control and Monitoring with C7 Overview Using the C7, you can visualize operating states and current process values. You can also enter information at the C7 that is written to the C7 CPU. You can also configure functions for machine diagnostics on the C7. The C7 provides a series of standard functions.
- Page 12 Introduction System Messages System messages display internal states of the C7. They indicate, for example, operator errors or problems in communication. This type of message has the highest display priority. If a problem occurs on the C7, the currently displayed event message is cleared and a system message is displayed.
