Functional Description:
The Modbus Coil Broadcast generic hardware operator provides access to a networking channel resource in the physical hardware. When the generic operator is linked to a specific networking hardware resource, it will broadcast a message over that channel resource using the Modbus protocol.

The Modbus Coil Broadcast operator encodes boolean input signal x into a communication message that it broadcasts over an industrial network. All devices connected to the network will receive the broadcasted message. But, only those controllers with a Modbus Coil Receiver operator "tuned" to that broadcast will actually decode the message.

The operator has a second digital input b that disables transmissions. When b = LOW, the operator broadcasts input x onto the network. When b = HIGH, the operator doesn't do anything.

User-Defined Properties:
Signal Name. A string label that identifies the broadcast signal. It is used to associate this Modbus Coil Broadcast operator in one schema with Modbus Coil Receiver operator(s) in other schemas.

Initial Broadcast Value. The signal value transmitted initially.

Display Disable Input. This property determines if the disable input pin b 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).

Comments: None.
