Explicit Message Connection

Device Status is available by reading Class 1, instance 1, attribute 5. Vendor specific interface
for alarms and diagnostic for Explicit Message Connections is defined as follows:
Presence of process alarm can be detected by reading class 29, instance 1, attribute 5 and
class 30, instance 1, attribute 5. The module mode (Run or another state) has to be checked,
because the alarm bit is set to 0 = OK every time the module is not in Run mode.
The module mode can be detected by reading class 120 Instance 5 Attribute 1.
The presence of module diagnostic events can be detected by reading class 120 Instance 6 At-
tribute 1.
Detailed reasons for process alarms and system diagnostic events can be found out by reading
all 60 attributes of Class 120 Instance 3 which contains the dedicated system status bytes.
