108 Series 90B ANNUNCIATOR INSTALLATION AND CONFIGURATION MANUAL
AN3135 Mode
The system has the capability of mimicking the existing AN-3100C Modbus
functionality. The object is to provide a system that is backwards compatible
with the existing AN-3135 Modbus Module used on AN-3100C systems. The
AN3135 mode is restricted to the default Functions of 03 to read alarm data and
06 and 16 being used to write fault and control data. The principal difference
between this and the point mode above is that the AN3135 mode is restricted to
64 points.
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.
