• Direction: The direction of the alarm event: whether this record indicates the limit

going out, or coming back into limit.

1 Going out of limit

2 Coming back into limit

• Limit Type: Each limit (1-8) has both an above condition and a below condition.

Limit Type indicates which of those the record represents.

0 High Limit

1 Low Limit

• Limit ID: The specific limit this record represents. A value in the range 0-7, Limit ID

represents Limits 1-8. The specific details for this limit are stored in the program-

mable settings.

• Value: Depends on the Direction:

• If the record is "Going out of limit," this is the value of the limit when the "Out"

condition occurred.

• If the record is "Coming back into limit," this is the "worst" value of the limit dur-

ing the period of being "out": for High (above) limits, this is the highest value

during the "out" period; for Low (below) limits, this is the lowest value during

the “out" period.

Interpretation of Alarm Data:

To interpret the data from the alarm records, you need the limit data from the

Programmable Settings [0x754B, 40 registers].

There are 8 limits, each with an Above Setpoint, and a Below Setpoint. Each setpoint

also has a threshold (hysteresis), which is the value at which the limit returns "into"
