Alarm State Mode

(only available in communication modules with part numbers starting with 1085- and 1086-)

The system can provide data reflecting the alarm state of the system. This mode
operates as output only (transmit alarms) from the system.
The alarm state data is present within a 16 bit register format as shown in the
table below. The data is in a nibble format (4 bits per point, 4 points per register)
and reflects the already established DMS3000/RTU3000 style format. Note the
control transfer is not supported in this mode as the control state of any point is
included within the data transferred.

Point Mode

The system can present or accept (transmit or receive) raw field input point data
plus alarm controls. Single and multiple register writes are supported. Data is
again presented in a 16 bit register format. The last word of a transfer of input
data may optionally contain control data.
The data layout for a sample system configured for point data will be as below.

AP refers to Alarm Point Channel. ACK refers to the Acknowledge Pushbutton
and RST refers to the RESET Pushbutton.
The local pushbutton controls (on the front of the Annunciator and other ones
connected to the external pushbutton inputs) can be transmitted (Tran) to a
remote device using Ack Tran and Rst Tran as shown. The Annunciator can
also receive (Rec) the pushbutton controls from the remote device using Ack
Rec and Rst Rec as shown.
