Port General Properties

Use the General tab in the Port Properties dialog box to enter general information for the port. You can define the following.

Description

Enter an optional description to help you identify the port.

Scan Rate

Enter the base scan rate for the port. Point scan rates will be multiples of the base rate.

You can specify a scan rate in Ticks (100 ticks = 1second), Seconds, Minutes, or Hours.

Retry Count

If the enabler cannot complete a setpoint (write/download) to a device due to any reason, retries are performed. Enter the number of retries to perform before reporting the action as "failed".

Enable

Set this check box if you want the port to be enabled when the project starts. If you clear this check box, the port will not be enabled when the project starts, and points will not be available for devices on the port.

Enable stale data

Check to keep the point available in most circumstances that would have made it unavailable. However the point value will be stale, meaning it is the last known value and may or may not have changed in the device.
