BAD 255

[MatheusNcam]

Good afternoon!
Could anyone help me? I'm running the same code provided, just changing the port and ip, and in the end, all the arrays have a "BAD 255", for example:
TEST4: [ 'BAD 255', 'BAD 255' ]

[plcpeople]

Are you able to post more information such as the console output of your program, information on PLC parts you're using, a Wireshark trace, etc? Bad 255 most often means no communication to the PLC - are you able to ping it?

[MatheusNcam]

I'll be able to send the information tomorrow, when I'll be in the office, but the model I want to get the information from is a Mitsubishi M70V Series PLC (CNC), I'm trying first via Ethernet cable and then via Modbus

[plcpeople]

Are you sure this CNC PLC supports the same MC protocol that the Mitsubishi FX3U and other Mitsubishi PLCs support? I have zero experience with Mitsubishi CNC but I did a quick search and I'm not convinced it supports this protocol.

Good evening, sorry I didn't send it sooner, but it's below:
I tried 3 ports (5002,683 and 111) and they got it "right"
Code:

var mc = require('mcprotocol');
var conn = new mc;
var doneReading = false;
var doneWriting = false;

var variables = { TEST1: 'D0,5', 	// 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: 683, host: '192.168.200.1', 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.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(); }
}

It doesn't seem to accept the write, so I think this CNC doesn't work with this protocol.

Is there a place in GX Developer to set up the MC protocol connection similar to what is described in the README?
