4 years ago Device in use is FX3GE-24M.
The code is as follows: var mc = require('mcprotocol'); var conn = new mc; var doneReading = false; var doneWriting = false;
var variables = { TEST1: 'D0', // 5 words starting at D0 TEST2: 'M6990,28', // 28 bits at M6990 TEST3: 'CN199,2', // ILLEGAL as CN199 is 16-bit, CN200 is 32-bit, must request separately TEST4: 'R2000,2', // 2 words at R2000 TEST5: 'X034', // Simple input TEST6: 'D6000.1,20', // 20 bits starting at D6000.1 TEST7: 'D6001.2', // Single bit at D6001 TEST8: 'S4,2', // 2 bits at S4 TEST9: 'RFLOAT5000,40' // 40 floating point numbers at R5000 }; // See setTranslationCB below for more examples
conn.initiateConnection({port: 5556, host: '192.168.1.250', ascii: false}, connected);
function connected(err) { if (typeof(err) !== "undefined") { // We have an error. Maybe the PLC is not reachable. console.log(err); process.exit(); } conn.setTranslationCB(function(tag) {return variables[tag];}); // This sets the "translation" to allow us to work with object names defined in our app not in the module //conn.addItems(['TEST1', 'TEST4']); //conn.addItems('TEST6'); conn.addItems('TEST1'); // conn.removeItems(['TEST2', 'TEST3']); // We could do this. // conn.writeItems(['TEST5', 'TEST7'], [ true, true ], valuesWritten); // You can write an array of items as well. //conn.writeItems('TEST4', [ 666, 777 ], valuesWritten); // You can write a single array item too. conn.readAllItems(valuesReady); }
function valuesReady(anythingBad, values) { if (anythingBad) { console.log("SOMETHING WENT WRONG READING VALUES!!!!"); } console.log(values); doneReading = true; if (doneWriting) { process.exit(); } }
function valuesWritten(anythingBad) { if (anythingBad) { console.log("SOMETHING WENT WRONG WRITING VALUES!!!!"); } console.log("Done writing."); doneWriting = true; if (doneReading) { process.exit(); } }

Hey, I can set up the connection with the device on an specific ipadress and port (5556). However, I get an error mentioning 'Timed out' as can be seen from the screenshot
My code is displayed as well.
Let me know if this is an issue with the PLC configuration or improper addressing of the data. Test.txt
