We are trying to create a device using the module [Advanced Modbus](https://inductiveautomation.com/moduleshowcase/module/automation-professionals-llc-advanced-modbus) with [system.device.addDevice](https://www.docs.inductiveautomation.com/docs/8.3/appendix/scripting-functions/system-device/system-device-addDevice). On every try I get

The script I'm running is:

`system.device.addDevice(deviceType = "ModbusClient", deviceName = "A-11", deviceProps = {"framing": "MODBUS_TCP", "hostName": "192.168.75.83:502", "maxOutstanding": 1, "execTimeout": 4000, "tFramePlus": 0, "shortBrowse": True, "txIdLimit": 0, "elamSupport": False})`

| `Advanced Modbus Driver -- 1.2.1 (b260092138)` |
| --- |
| `8.3.4 (b2026030309)` |

@pturmel might be interested.  
The module is compatible with the function?

Currently, I have a SDK script that does it pushing are creating the config.json, resource.json and unit.csv on the current mode.

See page 14 in the user manual for the v8.3 driver. (Delivered with the module, accessed from the gateway.)

I suppose I should replace the v8.1 manual with the v8.3 manual on my site....

I see what you are saying but still. Running

```python
system.device.addDevice(
   deviceType = "ModbusClient",
   deviceName = "A-12",
   deviceProps = {
       "comms.framing": "MODBUS_TCP",
       "comms.hostName": "192.168.75.83:502",
       "behavior.maxOutstanding": 1,
       "behavior.execTimeout": 4000,
       "behavior.tFramePlus": 0,
       "behavior.shortBrowse": True,
       "behavior.txIdLimit": 0,
       "behavior.elamSupport": False
   }
)

```

or

```python
system.device.addDevice(
    deviceType="ModbusClient",
    deviceName="A-12",
    deviceProps={
        "comms": {
            "framing": "MODBUS_TCP",
            "hostName": "192.168.75.83:502"
        },
        "behavior": {
            "maxOutstanding": 1,
            "execTimeout": 4000,
            "tFramePlus": 0,
            "shortBrowse": True,
            "txIdLimit": 0,
            "elamSupport": False
        }
    }
)

```

Also, I need to add the unit.csv and I ready don't know how to the "delivered via API", which API?
