This module is the Titanium implementation of IEC 60870-5-104 communication standard. The library can be used to program clients as well as servers. The module is work on progress and not ready for production.
First we need a connection to the server:
var IEC60870 = require("de.appwerft.j60870");
var conn = IEC60870.createConnection({
address : "192.168.0.3",
port : 1234,
commonAddressFieldLength : INT, // length of the Common Address (CA) field of the ASDU
cotFieldLength : INT, // length of the Cause Of Transmission (COT) field of the ASDU
ioaFieldLength : INT, // length of the Information Object Address (IOA) field of the ASDU
maxIdleTime : INT, // maximum time in ms that the connection may be idle before sending a test frame
maxTimeNoAckReceived : INT, // maximum time in ms that no acknowledgement has been received (for I-Frames or Test-Frames) before actively closing the connection.
maxTimeNoAckSent : INT,
maxUnconfirmedIPdusReceived : INT
});
conn.connect(require("onConnectHandler"),onErrorHandler);Alternatively to constructor parameters you can provide a json file in you folder Ressources. In this case you can simple connect by
var conn = IEC60870.createConnection();
conn.connect(require("onConnectHandler"),onErrorHandler);The default path of configuration file j60870.json you can overwrite in your tiapp.xml with parameter J60870_PATH. In this case you can only connect one server.
Inside of onConnectHandler.js can can implement:
module.exports = function(_connection) {
_connection.startDataTransfer();
_connection.send();
};
