Series 90B ANNUNCIATOR INSTALLATION AND CONFIGURATION MANUAL
Event Data
Event data may be read in blocks of 10 events at a time. These appear in a
block of 60 registers (6 per event) located at the configured Start Address plus
1000 i.e. if the Start Address is set to 40001 then the events appear at 41001-
41060. Once ten events are read then the registers are reloaded with any
subsequent ones from the 500 event buffer. If no event has occurred, then all 12
bytes are filled with FF HEX.
The event data format is as shown below:
1 = Point on
0 = Point off
An example of the register format for the 10 events is shown below:
Year (0-99) high byte / Month (1-12)low byte
Day of month (1-31)high byte /Hours (0-23) low byte
Minutes (0-59) high byte / Seconds (0-59) low byte
Milliseconds (0-999) two bytes
