TCP ECCONRESET #129

Open anacarolina-ms opened 1 year ago

anacarolina-ms commented 1 year ago

Hey! I'm working with your node on node-red for reading from a plc S7-1200, rack 0 and slot 1 with external functions. But every time I send a readAllItems I get the response I want but the connection resets every time and never closes, even with dropConnection and connectionCleanup... I've been trying to solve it for a few days now, if anyone has any ideas...

var devices = msg.payload; // devices example: {"delta":0,"name":"10.255.3.214","rack":0,"slot":1,"data":"Q0.0","ip":"10.255.3.214","port":102}

msg = [];

let nodes7 = global.get('nodes7');
var conn = new nodes7({ globalTimeout: 2000 });
var doneReading = false;

devices.forEach((/** @type {{ modbus_id: any; modbus_ip: any; modbus_port: any; address: any; quantity: any; }} */ dev) => {
   var variables = {
      DATA: dev.data
   };

   conn.initiateConnection({ port: dev.port, host: dev.ip, rack: dev.rack, slot: dev.slot, debug: false }, connected);
   function connected(err) {
      if (typeof (err) !== "undefined") {
         // PLC FORA DO ALCANCE
         //console.log(err);
         node.error({
            "ip": dev.ip,
            "port": dev.port,
            "message": "ERRO! Falha na leitura do host " + dev.ip + "!",
            "error": err.code
         });
         flow.set("aguarda", false);
         conn.dropConnection();
         conn.connectionCleanup();
      }
      conn.setTranslationCB(function (tag) { return variables[tag]; });
      conn.addItems('DATA');
      conn.readAllItems(valuesReady);
   }

   function valuesReady(anythingBad, values) {
      if (anythingBad) { console.log("ERRO! Falha na leitura do host."); flow.set("aguarda", false); conn.dropConnection(); conn.connectionCleanup(); }
      //console.log(values);
      if (values.DATA != "BAD 255") {
         node.send({
            "topic": "TCP Response",
            "host": dev.ip,
            "port": dev.port,
            "rack": dev.rack,
            "slot": dev.slot,
            "data": dev.data,
            "payload": values.DATA
         });
      }
      doneReading = true;
      conn.dropConnection();
      conn.connectionCleanup();
   }

});

return msg;

Obs.: I want to read just one time and one address and close connection

minhbonghot commented 1 year ago

Hi carolina You can use process.exit() Here for example:

`var nodes7 = require('nodes7'); // This is the package name, if the repository is cloned you may need to require 'nodeS7' with uppercase S var conn = new nodes7;

var variables = { machineNo: "DB1,C0.10", };

conn.initiateConnection({ port: 102, host: '192.168.0.1', rack: 0, slot: 1, debug: 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]; }); conn.addItems("machineNo"); console.log("-----------------Init done-------------") conn.readAllItems(valuesReady) }

function valuesReady(anythingBad, values) { if (anythingBad) { console.log("SOMETHING WENT WRONG READING VALUES!!!!"); } console.log(values); process.exit() }`

anacarolina-ms commented 1 year ago

Hi minhbonghot, thanks for your reply!

When I use the external module 'process.exit()' inside node-red, apparently the process it ends is the execution of node-red itself, so this solution doesn't work for me...

If I could just disable reconnection maybe the problem would be solved, I don't know.

plcpeople commented 1 year ago

Hi Ana, can you please change this to turn more debugging output on and then post the output again:

var conn = new nodes7({ globalTimeout: 2000 });

to

var conn = new nodes7({ globalTimeout: 2000, debug: true });

I don't have node red set up right now so I edited your code to look like this in index.js and I ran it standalone, and it disconnects from the PLC and reconnects properly:

let nodes7 = require('nodes7');
var conn = new nodes7({ globalTimeout: 2000, debug: true });
var doneReading = false;
var net = require('net');
var server = net.createServer();    

server.listen(9000, function() {    
  console.log('server listening to %j', server.address());  
});

conn.initiateConnection({ port: 102, host: "10.8.1.50", rack: 0, slot: 1, debug: true }, connected);
function connected(err) {
  if (typeof (err) !== "undefined") {
     // PLC FORA DO ALCANCE
     console.log(err);
     conn.dropConnection();
     conn.connectionCleanup();
  }
  conn.setTranslationCB(function (tag) { return tag; });
  conn.addItems('Q0.0');
  conn.readAllItems(valuesReady);
}

function valuesReady(anythingBad, values) {
  if (anythingBad) { console.log("ERRO! Falha na leitura do host."); conn.dropConnection(); conn.connectionCleanup(); }
  //console.log(values);
  if (values != "BAD 255") {
console.log(values);
  }
  doneReading = true;
  // If I comment out the next 2 lines the connection stays active
  conn.dropConnection();
  conn.connectionCleanup();
  setTimeout(() => {
    conn.initiateConnection({ port: 102, host: "192.168.1.2", rack: 0, slot: 1, debug: true }, connected);
  }, 3000);
}

Hi Ana, another thing I was going to mention:

There are a couple of projects that implement nodes7 within node-red already: https://github.com/st-one-io/node-red-contrib-s7 https://github.com/Hilscher/node-red-contrib-s7comm

Would these help?

anacarolina-ms commented 1 year ago

Hey! So, I managed to make it work for a while, I tested it for 3 days in a row to do consecutive readings from a PLC, however after a while the reading stopped working and I started receiving ECCONRESET again, this time without reading...

I believe that the problem is not the PLC because I monitored direct readings by MODBUS/TCP and they worked during these 3 days...

The reading process only works again when I restart my Raspberry Pi.

I started the readings at: 2022-10-07T15:15:06.9640000-03:00 And the last one was: 2022-10-08T09:49:59.7200000-03:00

And about the nodes for Node-RED, I tested them but they do not allow me to dynamically change the Host IP and Port as I do in this code.

Is there any connection limit? Because it seems to me that it works for 2 days then it stops working as if it has reached a limit.

Anyway, thanks for the help, I'll keep researching and trying to fix this. I'm still open to suggestions!

Hello, I'm dealing with similar issues and what I found out is that if you keep connection alive (won't drop it and clean ) it will add new Used connection to S7 communication pool every time you make a function call image

When you reach the end of the pool then you get ECCONRESET and can only recover from it by restarting NR. I wonder if it is possible to keep connection alive and have some connections pool defined by argument?

function valuesReady(anythingBad, values) {
  if (anythingBad) { 
      //console.log("SOMETHING WENT WRONG READING VALUES!!!!"); 

      node.warn("SOMETHING WENT WRONG READING VALUES!!!!");
      conn.dropConnection(); 
      conn.connectionCleanup();
  }
  console.log(values);
  msg.payload = values;
  node.send(msg);

  conn.dropConnection();
  conn.connectionCleanup();
plcpeople commented 1 year ago

@anacarolina-ms can you please check open TCP connections between the Pi and PLC using netstat on the Raspberry Pi or by looking at the active connection information in TIA Portal or the PLC web page, if enabled? I set up a similar flow (I pasted the flow posted by @liulysk in issue #130 and it has run for a few hours talking to an S7-1200 and so far seems to release all connections.
