2.10 DNP 3.0 / Modbus SCADA Interface (Option 21P/21Q)
The optional DNP 3.0 / Modbus SCADA Interface Communication Board, allows the user to remotely connect to
the A36D battery charger. The board is equipped with four methods of communication; DNP 3.0, Modbus ASCII,
Modbus RTU and Modbus TCP. There are three different ports for connection to the communication board. The
three port types for connection are: RS232, RS485, and TCP (Ethernet).
Communication Interface Connection Procedure
Before making any connections to the A36D, ensure that the AC power is off at the main breaker box and the
charger’s breakers are off. Choose which port to use for connection (Ethernet, RS232, and/or RS485 – refer to
Figure 18). Connect the appropriate cable between the port on the communication board and the port on the
computer.
For more details on connection instructions as well as operation instructions refer to the DNP 3.0 & Modbus
SCADA Interface instruction manual included with the A36D. The DNP 3.0 & Modbus instruction manual is also
available online at http://www.lamarchemfg.com/ .
2.11 Battery Side Alarm Sensing (Option 565)
The optional battery voltage sensing board (S2A-407S) will allow the user to see the battery voltage even when
the charger DC breaker is open.
The Low Voltage and End of Discharge alarms are based on the voltage measured on the battery side of the DC
breaker when the option 565 is used. In case of sensing board failure, a special alarm “S2A-407S Failure” and
the Summary alarm will be triggered. Also, the controller will start using the charger side voltage sensing for
Low Voltage and End of Discharge alarms.
