Module Active

Functional Description:
In Design Pad a control node is formed by joining one or more modules together. Most modules are assumed to be "intelligent"---that is, they have processing and memory resources. The Module Active operator indicates if the module in the specified node position is responsive. The position of a module is relative to the leftmost module in the node. The leftmost module is in position 1, the module to its right is in position 2, and so on.

The operator output is HIGH if the module in the specified position is alive. This means that the module is responding to communication requests from neighboring modules. It does not necessarily imply that the module is executing a schema program or that no error conditions have been reported by that module.

The operator output is LOW if the module fails to respond to communication requests. This will occur when the module is removed from the node, if the module is not "intelligent", or if the module has sustained a hard failure (will not power up).

The operator has a single analog input that defines the module position that the operator is to report on. The module position can also be set as an operator property. If the input is connected, the property setting is ignored.

User-Defined Properties:
Object Name. A string label that identifies the operator

Display Module Position. This property determines if input pin x is visible in the schema diagram. Design Pad issues a warning upon processing the schema when the pin is visible but not connected. The warning message is not issued when the pin is not visible (when this property is not checked).

Module Position. The position in the node of the module of interest (the module whose health the operator reports on). This parameter is ignored when the module position input is connected.

Comments: None.
