Hi,

I'm trying to connect PLC and Thingworx via EMS.

In modbusExample.lua file, defining property for Thing is essential.

I put this property like this,

properties.Int16HoldRegExample = {value="300", dataChangeType="ALWAYS",pushType="ALWAYS", key ="holding_register/1/40001", handler="modbus_handler", basetype="NUMBER"}

But I can't connect.

Which URL does this "key" table mean?   PLC ,EMS or Thingworx Composer ?

please let me know information...

Best answer by PaiChung

The Modbus example is specifically for connecting using Modbus protocol.

You have a modbus protocol setup to your PLC?

the Key refers to the Modbus register that is to be read.

I use Modbus package and set up modbus protocol to my PLC.

Is it ok that only modbus register is included in key contents,for example key = "40001" ?

Unfortunately I'm not too familiar with how the modbus.lua is setup and how it processes the key that is put in.

Hopefully someone else can give some input on that.

Eric, what version of the MicroServer are you using? Do you have the Modbus package with it as well?

Hi,


Thanks for your fast reply. Sorry that i am very new to Thingworx.

How to check the version? The modbus package is that something like mobusscript.lua?

Fyi, i had actually downloaded the EMS to Syslink Systech SL-3000.
