NrioModule properties

NrioModule properties can be categorized into two groups:

As in other driver networks, the NrioModule has an available “Alarm Source Info” container slot you can use to differentiate NrioModule alarms from other component alarms in the station. See “Device Alarm Source Info” in the Drivers Guide for more details.

Device status properties

An NrioModule has typical device-level status properties (see “Device status properties” in the Drivers Guide). The following notes apply:

Status

Status of NrioNetwork communications to this NrioModule. Possible status flags include:
- ok - Normal communications, no other status flags.
- disabled - Enabled property is set to false, either directly or in NrioNetwork. While status is disabled, all child Nrio points have disabled status; NrioModule polling is suspended.
- fault - Typically an offline-added NrioModule (invalid 0 values for both Address and Uid).
- down - Error communicating to the Nrio processor on I/O device—possibly an RS-485 communications problem if a remote I/O module.
Enabled

Either true (default) or false. Can be set directly or in parent NrioNetwork. See Status disabled description above.
Health

Contains properties including timestamps of last “ok” time and last “fail” time, plus a string property describing last fail cause.
Fault Cause

If status has fault, describes the cause (e.g.: “Invalid UID: Do Discover and Match”).

Config and I/O-related properties

In addition to common device-level Device status properties, NrioModule has the following unique properties, where most are read-only types unless noted:

Address

Integer between 1 and 16, unique among all NrioModules under the NrioNetwork. Automatically derived (and associated) with physical I/O devices upon an online Discover.
Device Type

Currently, this is Io16. Other device types may be available as other I/O hardware products (accessed using Nrio) are offered.
Uid

Unique ID. A six byte number, globally unique to this specific I/O hardware device. Automatically obtained from each device upon an online Discover.
Installed Version

Reflects the IO firmware revision installed in the I/O module/device.
Available Version

Reflects the IO firmware revision available in the JACE’s installed nrio module. If this version number is later (higher) than the installed version number, you can initiate an I/O firmware upgrade from the Nrio Device Manager. For more details, see About Upgrade Firmware.
Wink Output

(Writable) Specifies which digital output (relay output) is cycled On and Off when a “Wink Device” action is invoked on the NrioModule, where default is output 1. Note although the range is from 1 to 8, currently I/O hardware (onboard “M2M JACE”, 10-16-485) has only four relay outputs (1-4).
Wink Duration

(Writable) Specifies how long the wink output is cycled On and Off, at constant rate 1 second On, 1 second Off. Default value is 10 seconds, with a range from 5 seconds to 1 minute.
Wink is typically used only in the early stages of station configuration of NrioModules under an NrioNetwork. Following the competition of job engineering, you may wish to “hide” the Wink Device action on NrioModules, to prevent possible (inadvertent) unintended cycling of loads. For related details, see About Nrio Wink.
LocalIo16 or Io16_n

(Nrio16Points) The “Points” extension/container for all Nrio proxy points for this I/O device. The name of this points extension reflects the name of the parent NrioModule component. Currently, no other properties exist. The default view is the Nrio Point Manager, which you use to add, modify, and delete child Nrio proxy points. These provide the interface to I/O hardware points. For more details, see the section Nrio Point Manager.
Io Status

(NrioStatus) Contains a concatenated “Io Status” summary of current IO values in hexadecimal coded format, and numerous component children with individual hexadecimal values.
Typical usage of Io Status values are for advanced debug purposes only. This is the value last received by the actrld process running on the JACE. For related details, see About the actrld (access control daemon).
