Correct, base Ignition only supports connecting as a Master modbus device.

However, some third party modules, like Automation Professional's [Advanced Modbus Driver](https://forum.inductiveautomation.com/t/automation-professionals-advanced-modbus-driver/41312), allow you to configure Ignition as a Modbus server device or a Modbus Master device, while also adding additional helpful functionality.
