This chapter contains a summery of commands and indications used to program the
IEC-Q. An overview of the following codes is given
• C/I channel commands and indications
• Predefined Monitor channel messages
• Predefined EOC messages
Furthermore, several examples for programming codes are given. This includes
• programming code for the C/I and the Monitor channel in the microprocessor mode
• Programming code for the power controller interface, which applies only in
• Programming code for test loop-backs (section 6.7)
• Programming code for activation and deactivation control for all important
Note 65: Programming the C/I channel and the Monitor channel can be performed
