3)Updated data

4)Acknowledgment signal

1)A satellite detects a breakdown of the back-up master through the system retry function when sending updated GLU data (and clerk data*) to both the master and back-up master. At this point, the message “BACKUP DOWN” appears in the pop-up window of the display of the satellite.

2)The master declaration operation must be done at the master. This operation informs all the satellites of the breakdown of the back-up master.

3)Each satellite in the IRC system starts sending updated GLU data (and clerk data*) only to the master.

4)The master receives the data and sends back an acknowledgment signal to the satellites.

*Only for the centralized clerk file system

The master declaration procedure is the same as “(1) When the master breaks down.”
