Description
Data Type: Unsigned16
This array contains one element for each
status class. The bits 0 to 14 of each element
mirror the statuses of individual Binary
Messages or device specific events. Bit 15
(MSB) is the OR combination of all Binary
Messages belonging to the status class and
shows if at least one of these Binary Messages
is active.
Data Type: Unsigned16
Contains all configured Binary Messages, each
Binary Message is represented by one bit. The
order number of the bits in the bit string is the
same as the order fo the Binary Messages in
the block parameter list of the Alarm
Transducer Block
Data Type: Unsigned16
Number of configurable Binary Messages in
the device.
