MultiZone for Java

This library is designed to simplify modbus communications with a Bacharach Multi-Zone leak detector.

This library can be included in your project easily with maven. First add the jitpack repository.

<repositories>
	<repository>
	    <id>jitpack.io</id>
	    <url>https://jitpack.io</url>
	</repository>
</repositories>

Then include this library as a dependency.

Getting Started

Below is some example code to show how to read the current parts per million and alarm status for each zone. Bacharach documentation states that a modbus master device, such as this library, should not poll the current zone statuses more often than every 20 seconds. (Manual B.3.3.)

	// This object represents a Bacharach MultiZone device on the modbus serial network.
	// /dev/serial1 - This is the default RS485 port name on the Comfile PI 
	MultiZoneDevice one = new MultiZoneDevice(1, "/dev/serial1");
	
	// Read the current ppm and alarm status for zone 1.
	CurrentZoneStatus single = one.getCurrentZoneStatus(0);
	System.out.println(String.format("Single Read - Zone 1: %s ppm - %s alarm status", single.getPPM() + "", single.getAlarmStatus() + ""));
	
	// Read the status of all 16 zones.
	int address = 1;
	for (CurrentZoneStatus status : one.getAllCurrentZoneStatuses()) {			
		System.out.println(String.format("Zone %s: %s ppm - %s alarm status", address + "", status.getPPM() + "", status.getAlarmStatus() + ""));
		address++;
	}

Roadmap

• Implement the 3000 series, write, Function Code 06 registers. (Manual Section B.4.2.)
• Fully implement the block mode registers for advanced remote setup and complete detail access. (Manual Section B.5.)

Release History
