Description

Sylk Device

Select the required Tr4x device from the drop-down menu.

Status

Read-only point. Shows the status of the parameter. (alarm, fault, overridden, disabled, down, stale, null, unackedAlarm). For further details see Sylk Component Status Behaviors.

faultCause

Read-only point. Indicates the reason why the parameter is in fault. This property is empty unless a fault exists. When there are more than one errors, the fault cause shows only the error which is at the top of the list of errors. If the error is corrected, the next error is shown.

sendInterval

Seconds

Send interval is the time between the end of a timeout period or completion of a network request and the next request for data on the network. Default is 5 seconds.

The category defined by the user while configuring Sylk parameters. By default, it shows Category as category.

paramPermissins

User can select the viewing option for the parameter. Select the parameter as viewable by Contractor Only or Tenant Read Only from the drop-down menu. If Contractor Only is selected, only the contractor can view the parameters in the wall module. If Tenant Read Only is selected, tenant can view the parameters, but cannot make any changes in the parameters.

enableFD

The time it takes for a failure to be reported to the Sylk device.

"Yes": If the parameter has not received an update from the BACnet network source within the fail detect time, an alarm is generated, and the current value is set to invalid.

Note: The time it takes to detect a failure is determined by the update rate that has been set.

"No": No means that the object will retain the last value written to it until the BACnet network source changes.

Out Save

Master Sync Enabled : If you set it to "true" the last output will be set as output for one cycle after the controller restarts. The application can use it to return to the same state before the controller restart.

Out: To enable or disable the Out feature.
