API
datastore
- datastore.init(mongodbOptions, mqttOptions)
- datastore.quit()
- datastore.getRealData(tag array, [callback])
- datastore.upsertRealData(scadaId, parameters, [callback])
- datastore.updateRealData(scadaId, parameters, [callback])
- datastore.deleteRealDataByScadaId(scadaId, [callback])
- datastore.getHistData()
- datastore.insertHistData()
datastore.init(mongodbOptions, mqttOptions)
Connects to MongoDB and MQTT broker specified by the given options. You have to specify the following options, for example:
let mongodbConf = {
host: '127.0.0.1',
port: 27017,
username: 'admin',
password: '1234',
database: 'mongodb'
};
let mqttConf = {
host: '127.0.0.1',
port: 1883,
username: '',
password: ''
};
datastore.init(mongodbConf, mqttConf);
datastore#quit()
When no need to use datacore, close the connection.
datastore#getRealData(tag array, callback)
Get real-time tag data by the given tags list, a tag has scadaId
and tagName
properties.
The callback is called when all tag data has been gotten.
For example:
let t1 = {
scadaId: 'scada1',
tagName: 'Foo1'
};
let t2 = {
scadaId: 'scada2',
tagName: 'Foo2'
};
datastore.getRealData([t1, t2], (err, response) => {
if (err) {
console.error(err);
} else {
console.log(response);
}
});
datastore#upsertRealData(scadaId, parameters, callback)
Update real-time tag value. If tag is not found, tag will be inserted. The callback is called when tag value has been updated.
For example:
let scadaId = 'scada1';
let t1 = {
tagName: 'Foo1',
value: 100,
ts: new Date()
};
datastore.upsertRealData(scadaId, t1, (err, response)=> {
if (err) {
console.error(err);
} else {
console.log('success: ' + response.ok);
}
});
datastore#updateRealData(scadaId, parameters, callback)
Update real-time tag value. The callback is called when tag value has been updated.
For example:
let scadaId = 'scada1';
let t1 = {
tagName: 'Foo1',
value: 100,
ts: new Date()
};
datastore.updateRealData(scadaId, t1, (err, response) => {
if (err) {
console.error(err);
} else {
console.log('success: ' + response.ok);
}
});
datastore#deleteRealDataByScadaId(scadaId, callback)
Delete real-time tag data record by the given scadaId. The callback is called when tag value has been deleted.
For example:
datastore.deleteRealDataByScadaId('scada1', (err, response) => {
if (err) {
console.error(err);
} else {
console.log('success: ' + response.ok);
}
});
datastore#getHistData(parameters, callback)
Get history tag data according to the input parameters. The callback is called when data has been gotten.
For example:
let t1 = {
scadaId: 'cda43195-7a0a-4903-a533-d333d8c5f9d9',
deviceId: 'P02_SCADA',
tagName: 'ATML_PACPRF:CTR',
startTs: new Date('2015-01-01'),
endTs: new Date(),
orderby: -1,
limit: 10
};
datastore.getHistData(t1, function (err, response) {
if (err) {
console.error(err);
} else {
console.log(response);
}
});
datastore#insertHistData(parameters, callback)
Insert history tag data. The callback is called when data has been inserted.
For example:
let t1 = {
scadaId: 'cda43195-7a0a-4903-a533-d333d8c5f9d9',
deviceId: 'P02_SCADA',
tagName: 'ATML_PACPRF:CTR',
value: 100,
ts: new Date()
};
datastore.insertHistData(t1, function (err, response) {
if (err) {
console.error(err);
} else {
console.log('success: ' + response.ok);
}
});
