A4.4
This enables two digit decimal numbers to be output as a single character hexadecimal number.
Decimal to hexadecimal conversion:
Decimal Hexadecimal Decimal Hexadecimal
0 0 8 8
1 1 9 9
2 2 10 A
3 3 11 B
4 4 12 C
5 5 13 D
6 6 14 E
7 7 15 F
8 8
e.g. With 01100 67X and 01100 68X software; if alarm parameters 93 and 92 are active, their sum
of equivalent decimal numbers is 8 + 4 = 12. The equivalent hexadecimal number is C and it is this
which is output on the datalink. Hence if no other alarms are active, the alarm status will be C000.
Similar outputs are obtained from 01100 66X software, but in the example given above the output
would be 0300.
The complete allocation of alarms is:
