An Nrio network (NrioNetwork or M2mIoNetwork) is a top-level container component for “one access path of Nrio” in a station.

In the initial nrio release, only a specialized type of Nrio network component is used: the M2mIoNetwork, which supports the integral “onboard I/O” on an “M2M JACE” (JACE-202 Express). Later, as remote I/O modules (10-16-485) become available, there may be multiple Nrio access paths, and thus a need for multiple Nrio networks in the station (using NrioNetwork components). Essentially, a separate path (network) is required for each of the following: any JACE onboard I/O, remote I/O modules wired to the JACE’s onboard RS-485/power connector, remote I/O modules wired to any RS-485 option card port.

Any Nrio network should reside in the station’s DriverContainer (“Drivers”). The simplest way to add an NrioNetwork is from the “Driver Manager” view, using the “New” command. Or, you can simply copy an M2mIoNetwork or NrioNetwork from the nrio palette into Drivers. This is the recommended method for an M2M JACE station to add an M2mIoNetwork—see M2mIoNetwork for details.

The JACE platform must have the nrio module installed. Otherwise, an error occurs explaining that the nrio module is missing. If this occurs, install the nrio module in that JACE and repeat the operation.

An Nrio network component has the typical collection of slots and properties as most other network components. For details, See “Common network components” in the Drivers Guide. The following sections explain further:
