Property | Description |
|---|---|
Name | The name of this item |
Enabled | If checked the , Edge ACM will poll this device when running |
Publish Rate | The time, in milliseconds, between Device Data Messages |
Alter Publish Rate on Point Limits | If enabled, tag limits are monitored by the publisher and the publisher will switch to the Altered Publish Rate if any tag is out of limits |
Altered Publish Rate | |
The time, in milliseconds, between Device Data Messages if any tags assigned to this device are out of limits (Limits are set on the tag object)Device Address | The Modbus unit address of the device, valid . Valid values 0-65535. |
Modbus TCP | Sets the Modbus message encoding to TCP enabled. |
Register Set | Defines the specific register set to use when polling the device. Eight register sets are currently included with the application (definitions found below table):
|
Custom Modbus Register Set | The Modbus Register Set object associated with this device if Custom “Custom” is selected in for the Register Set above. |
Addressing Type | Defines the End Device addressing type for special configurations of Modbus. There are four options to choose from:
|
Null Terminated Strings | Determines if the string registers will be null terminated when written |

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.
|
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. |
