From your PC, use the Niagara Workbench 3.n.nn installed with the “installation tool” option (checkbox “This instance of Workbench will be used as an installation tool”). This option installs the needed distribution files (.dist files) for commissioning various models of remote JACE platforms. The dist files are located under your Niagara install directory under a “sw” subdirectory.

For details, see “About your software database” in the Platform Guide.

Apart from installing the 3.n.nn version of the Niagara distribution in the JACE, make sure to also install the modbusCore module, plus any specific modbus<type> module needed (for example, modbusAsync, modbusTcp, and so on). Upgrade any modules shown as “out of date”.

For details, see “Software Manager” in the Platform Guide.

Following this, the remote JACE is now ready for Modbus configuration in its running station, as described in the rest of this document. See the next section Modbus Quick Start for a series of task-based procedures, as well as other sections Modbus Meets NiagaraAX and NiagaraAX Modbus Representation for conceptual and operational topics.
