Configuration
Property | Description |
|---|---|
Name | The name of this item |
Enabled | If checked, Edge ACM will poll this device when running |
ROC Series | The type of ROC you wish to poll:
|
Industry Canada ROC | Indicates that the device has been configured to Industry Canada standards |
ROC Unit | Sets the ROC Unit Address, valid values 0-255 |
ROC Group | Sets the ROC Group Address, valid values 0-255 |
Host Unit | Sets the Host Unit Address, valid values 0-255 |
Host Group | Sets the Host Group Address, valid values 0-255 |
Max Message Length | Sets a limit on the maximum number of bytes to send in a single message to the End Device, valid values 8-240 |
Read User Opcode Data Via Opcode 10 | This option causes eACM to read user opcode points using ROC protocol opcode 10 instead of opcode 180. This can be a more efficient way to read user opcode points, as long most of the requested points are continuous. If there are many gaps between requested user opcode points, then this option may not be desirable, as gaps will cause items to be polled in separate reads. This option is sometimes required to read user opcode data sourced from a user program running the ROC device that cannot be read with opcode 180 |
Tag Groups | The Tag Groups that are associated with this device. Edge ACM will only poll this device for the tags in the groups selected here |
Connection Settings | The object that contains the connection settings Edge ACM will use to connect to the End Device |
Folder | The parent folder for this item |
Comm Stats
Items available for publishing:
Property | Description |
|---|---|
Internal Tags Publishing Group | An integer ID (0-255) that can be used to map the included Comm Stat tags in this device to a publish schedule. |
Include Active Items tag | Publishes the ActiveItems tag which is a count of the total number of tags on this device. |
Include Barometer tag | Publishes the Barometer indicator. Note: The communications barometer represents the marginal success rate of communications. For each poll cycle that does not receive a response for one or more poll messages, the barometer will increase by two (2), with a maximum value of 100. For each poll cycle that does receive a valid response for all poll messages, the barometer to decreases by 1, with the lowest value being 0. These barometer changes cause failures in communications to show up quickly as the barometer rises. However, good communications must be maintained longer and more steadily for the barometer to fall back to 0. |
Include Comm Status tag | Publishes the CommStatus tag which represents the status of the communication link to the device. The value will be 1 if a communication link to the device can be established – even if the device does not respond to polls. The value will be 0 if a communication link cannot be established to the device. |
Include Demand tag | Publishes the Demand tag which, when written to, will trigger an out of schedule poll of all tags on the device. |
Include Incomplete Poll tag | Publishes the IncompletePoll tag which is set to false at the beginning of each poll. The value changes from false to true if the last poll attempt was incomplete. |
Include Last Poll Attempt Time tag | Publishes the LastPollAttemptTime tag which is updated with the date time stamp of the last poll attempt in UTC (without time zone bias). |
Include Last Poll Failure Code tag | Publishes the LastPollFailureCode tag which is updated with an integer value indicating the result of the last poll.
|
Include Last Poll Length tag | Publishes the LastPollLength tag which is updated with the length (in bytes) of the last poll message sent to a device. |
Include Last Poll Success Time | Publishes the LastPollSuccessTime tag which is updated with the date time stamp of the last successful poll in UTC (without time zone bias). |
Include Seconds Since Complete | Publishes the SecondsSinceComplete tag which is updated with the seconds since the last complete poll. |
