The Digital Output block operates in a chain by sending digital values to an I/O address based on the value it receives from its upstream block. For example, the Digital Output block can control the status of an electric motor by passing the 1 or 0 value it receives from an upstream Boolean block's equation, as shown in the following figure.
Using the block's Open or Close (Labels) fields, you can enter the words OFF and ON to represent the motor's status and can display this text to operators when they view the status in the iFIX WorkSpace.
The Digital Output block, when used as a stand-alone block, allows either its Initial Value field, other blocks, or an operator to control the values sent to the I/O address. The following figure shows this configuration.
