Reading other than memory area D

[danibjor]

I tried to read data from memory area HR.

Googled around a bit and found HR to be 0x80.
I've updated the constants.js file to include HR area like this:

module.exports.MemoryAreas = {
    'H' : 0x80,
    'D' : 0x82
};

I've added a console.log(temp) to fins_client.js' _translateMemoryAddress function just to verify that MemoryArea is in fact set to 0x80.

I do a simple .read('H00300', 24) and do a console.log(msg) in the 'reply' event method:

{
  remotehost: '10.0.0.233',
  sid: 9,
  command: '0101',
  response: '0000',
  values: [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ] 
}

In Omron Sysmac Studio, we inspect the H3xx memory area and it dones not look like this. Values should be like [big integer, 0, 2, ...]

Any ideas?

I could add that reading from D works fine - so the question really is if the headers or something else should change when reading from DM to HR (other than memoryArea byte)

Fixed it - HR register is 0xB2, not 0x80

Hi Danibjor,

Sorry for the late response. If you have any other problems let me know.
If you haven't seen this already, this manual will have memory codes and other helpful information:

Added a pull request with update to read HR register.

Hi all, does anyone know if it is possible to read EM Area of omron PLC via fins command?
I can't find a reference to what command code should be use.

yes, you have to use 0xA0 command. (see complete list below)

        /// <summary>Extended Memories</summary>
        EM = 0xA0,
        /// <summary>CIO</summary>
        CIO = 0xB0,
        /// <summary>Work Area</summary>
        WR = 0xB1,
        /// <summary>Holding Bit</summary>
        HR = 0xB2,
        /// <summary>Auxiliary Bit</summary>
        A = 0xB3,
        /// <summary>Data Memories</summary>
        DM = 0x82
