Issue
The Momentary Start / Stop (SS) object in a MNB controller is not working. The OutStrt output property remains ON and does not pulse off.

Resolution
The OnPulse input property is set higher than the required minimum of 2 seconds. In order for the logical outputs to work (OutStrt & OutStp), physical hardware tags must be assigned to the physical outputs (AddrStrt & AddrStp). This is required when using the Momentary SS object in any MNB controller.
The following logic can be used in place of the Momentary SS object to generate an equivalent OnPulse.
