IAS WD Structure and Attribute

The structure definition for the IAS WD cluster is:

typedef struct
{
#ifdef IASWD_SERVER   
  zuint16   u16MaxDuration;
#endif    
  zuint16   u16ClusterRevision;    
} tsCLD_IASWD;

where:

u``16MaxDuration is the maximum duration, in seconds, for which the alarm can be continuously active (for example, a siren sounded). The range of possible values is 0 to 65534 seconds and the default value is 240 seconds.
u16ClusterRevision is a mandatory attribute that specifies the revision of the cluster specification on which this cluster instance is based. The cluster specification in the ZCL r6 corresponds to a cluster revision of 1. The value is incremented by one for each subsequent revision of the cluster specification. This attribute is also described in Section 2.4.
