Create, edit or disable a Modbus gateway in Chart’nX

In the Chart’nX Modbus catalog, a Modbus gateway describes the hardware reached over the network (IP address and port) and the project’s Can’nX box that records its data. Its reading configurations are then attached to it.

Intended for administrators and installers, in the Chart’nX energy or water generator. To remove a gateway from the project, follow Archive or delete Modbus items instead: deletion has different consequences from deactivation.

Before you start

• Prepare the network address of the hardware: IP address and port.
• Identify the project’s Can’nX gateway that should record the data. The form offers the compatible Kloud’nX and Emergy’nX gateways present in this project.

Create the gateway

1. Open the Modbus catalog, then click + New Modbus gateway; on a small screen, the label may be + Modbus gateway. The configuration form opens with the gateway creation fields. In a new configuration, the same + New Modbus gateway button, under the Modbus gateway selector, also opens these fields.
2. Fill in Gateway name, for example “Workshop gateway” (fictitious name), then IP address and Port. The initial port is 502: keep it only if it matches your device.
3. In Can’nX gateway that will save the data, choose the box intended for this project.
4. Click Create gateway. These four pieces of information are required. After success, the creation fields close and the new gateway is selected for the Modbus configuration.
5. Continue if necessary with Declare a Modbus configuration. To only create the gateway, then click Back in the catalog to return to the list.

The creation is saved immediately. Cancel in the gateway fields discards what has not yet been created; canceling a configuration or a dashboard afterwards does not remove a gateway that has already been created.

Edit an existing gateway

1. In Active, click the Edit gateway pencil in the gateway header.
2. Check the name, the IP, the port and the associated Can’nX gateway.
3. Click Save, or Cancel to close the fields without saving.

If the former Can’nX gateway appears as missing from this project, identify the correct destination with the person responsible for the installation before changing this association.

Disable or re-enable a gateway

The header switch has the tooltip Disable gateway when the gateway is active, or Enable gateway when it is disabled. A click applies the change immediately.

• Deactivation affects the reading of all this gateway’s configurations. The Disabled badge appears and reading tests become unavailable. The configurations are kept.
• To resume, re-enable the gateway if this action is planned, then check a reading and the data.

Check the result

The gateway appears in Active with its IP address and port. Just after creation, the reading test may remain unavailable: follow the message inviting you to test from the catalog once the gateway is online, then test a reading.

Troubleshooting

• The correct Can’nX gateway is missing from the list: have its attachment to the project checked by the administrator or contact support. Do not select another box just to complete the form.
• Fill in the gateway fields first: complete the flagged fields.
• Could not save the Modbus gateway or Could not change the gateway state: return to the catalog and check the state shown before repeating the operation.

If the result remains uncertain, contact support@can-nx.com with the message and the action attempted.
