SUMMARY

The AbvSpu provides functions to read and write process attributes (status, measuring value, alarm information) as well as to control process parameters (limits, delay times, etc.).

PARAMETERS (IN)

obj (INT)

Object Number

PARAMETERS (OUT)

yAt (BYTE)

Alarm Typ

bOk (BOOL)

1=okay, 0=error

PARAMETERS (IN_OUT)

DESCRIPTION

GetAT_ex() - Alarm Typ
Returns the defined Alarm Type for the actual status.

The function is defined for analogue Measuring Points (MP) only.

• For binary MPs always Alarm Typ=0 is return.
• For Objects of the type 'Process Variables' <yAt=0> and <bOk=0> is returned.
• In case of an error <bOk=0> is returned.
• Possible Errors:
  • a) Invalid Object Number
  • b) Wrong Object Type

The Alarm Type is calculated from the Alarm Level of the actual status, whereby it is distinguished between the direction of the alarm (alarm up / normal down, respectively alarm down / normal up).
The Alarm Type is calculated according the following table:

Level	Direction	Alarm Type
0	down / up	0
1	down	0
2	down	3
3	down	5
4	down	11
5	down	9
1	up	0
2	up	2
3	up	4
4	up	10
5	up	8
