7. Description of dialog-table words
C
Depending on the type of display unit, more or fewer alarms may be
permitted. Nevertheless, the structure of a word used to signal alarms is
always as follows: One 16-bit word, where each bit represents an alarm.
When several alarm words are positioned in a device, the alarms are
numbered bit by bit, starting with the least-significant bit in the lowest
order address (bearing the number 1) and ascending towards the
most-significant bit and the highest-order address:
When several alarm words are defined in a given device, these words
are always located in consecutive addresses: There cannot be a gap
between alarm numbers.
 Set terminal clock
This set of 16-bit words, each divided into 2 bytes, enables the control
system to update the display unit real-time clock.
