To configure your pod to communicate with a Modbus Master, double-click the Modbus Slave System icon. The Modbus Slave System Settings window is displayed and a list of pods connected to your appliance appears. Using this window you can assign slave IDs to the available sensor pods and view the Modbus mapping of all pods and sensors configured on the current appliance.

Note: All sensors are Read-Only. Sensor states cannot be set with Modbus commands.

In the following procedures, it is assumed that you are starting from the Modbus Slave System Settings window.

Assigning a slave ID to a pod

To assign a Modbus slave ID to a pod:

1.Select one or more pods from the list and click Generate Slave ID.

2.A slave ID is generated automatically and assigned to each selected pod.

If you wish to manually assign a slave ID to a specific pod:

1.Select the pod from the list and click Modify Pod Settings....

2.In the Modbus Slave Sensor Register Settings window, click the Slave Address drop-down menu and select the slave ID you wish to assign to the pod. If the ID does not appear in the list, it is already assigned to a pod.

Removing a slave ID from a pod

To remove an assigned slave ID from a pod, select one or more pods from the list and click Remove Slave ID. Alternatively, you can click Modify Pod Settings... and select “No Slave Mapping” from the Slave Address drop-down menu.

Viewing the Modbus map

To view the mapping of all assigned Slave IDs and register addresses, click View Modbus Map.

The Modbus map is a summary of all Modbus information associated with the appliance. The information in the map can be exported to a text file for entry into the Modbus master map.

Note: After assigning slave IDs to pods, you must click Apply to save your changes before viewing the Modbus map. Otherwise, the newly assigned pods will not be included in the Modbus map.

Note: Up to 500 sensors can be seen for each Modbus pod or device. Pods or devices with more than 500 sensors will be indicated by a yellow highlight of the pod or device in the Modbus Slave System pane.
