Chapter 10 Operate the Module
The example indicates the status of voted alarm number 2.
However, the voted alarm instance that is provided in the status assembly is a
value from 1…13. To get the voted alarm instance, as referenced to the AOP
(0…12), subtract 1 from the decimal value of the presented 4-bit value.
Table 68 - Alarm Status Structure
The status structure consists of these parameters.
The data type for each attribute is either an ‘INT’ (16 bits), or a ‘DINT’ (32
bit). In each case, the state of the individual bits, as provided in Tab l e 67
, define
the status. It is possible for multiple bits to be set.
Relay Status Structure
The relay status structure contains the parameters that are shown in Table 69.
It communicates the status of the single on-board relay (relay 0) of the dynamic
measurement module. It also communicates the status of the relays in each of
the up to three connected expansion relay modules (relays 1...4, 5...8 and
9...12). The table consists of discrete bits, one per relay. When set, the bit
indicates that the associated relay is energized.
