jmmoser / node-drivers Goto Github PK

I tried running these two examples:

README

const { TCP, CIP } = require('node-drivers');

const tcpLayer = new TCP('1.2.3.4');
const logix5000 = new CIP.Logix5000(tcpLayer);

console.log(await logix5000.readTag('tagname'));

Logix5000

  
const { TCP, CIP } = require('node-drivers');

const tcpLayer = new TCP({ host: '1.2.3.4', port: 44818 });
const logix5000 = new CIP.Logix5000(tcpLayer);

(async () => {
  try {
    console.log(await logix5000.readTag('R03:9:I.Ch1Data'));
  } catch(err) {
    console.log(err);
  }

  await tcpLayer.close();
})();

And both examples when I run node script.js I get this error:

const tcpLayer = new TCP({ host: '192.168.1.100', port: 44818 });
                 ^

TypeError: TCP is not a constructor

Node version: 10.9.0.

code

const { Layers } = require('node-drivers');
const tcpLayer = new Layers.TCP({ host: '192.168.0.230', port: 44818 });
const eipLayer = new Layers.EIP(tcpLayer);
const cipPCCCLayer = new Layers.CIP.PCCC(eipLayer);
const pccc = new Layers.PCCC(cipPCCCLayer);

pccc.typedWrite('F8:1', 0, (err)=> { if (err)console.log(err);})
pccc.typedRead( 'F8:1', (err, value)=> {
if (err)
console.log(err);
else console.log(value);
})

return this
$ node test1.js
{ message: 'Invalid parameter or invalid data',
info:
PCCCPacket {
command: 79,
transaction: 1,
data: ,
status:
{ code: 240,

description: 'Remote: Error code in the EXT STS byte' } } }
2.2779507836064226e-41

Note:
F8:1 has a value 1.00000
F8:2 has a value 2.00000

Any help please ?
Thanks,

Hello everybody

Somebody know if its works in micrologix?

Hi,
I've tried running the example below after installing node-drivers:
"Read/Write a tag from a PLC-5, SLC 5/03, or SLC 5/04 processor using PCCC embedded in CIP:"
However, I keep getting the following error:

console.log(await pccc.typedWrite('N10:47', 1000));
^^^^^

SyntaxError: missing ) after argument list

anyone have come across this issue?

Justin,

Questions
"node-drivers" use to work with a callback in the read Tag call.
Is this not possible any more?
I am not sure what "await" does. Does the node executive loop process other functions while waiting ?

  Also, can "node-drivers" talk to a A/B Compact-Logix or Control-Logix PLC ?
   If so, I see no examples of this. Seem like all the necessary low level code is in place for this.
