In Action
You configure the limit switch by giving it a name, for example "Float Switch Low", and then drag-and-drop the connections to any Soft-I/O pins. Mechanical switches "bounce" when they close. Because Soft-I/O is so fast, Soft-I/O can sense multiple "bounces" of the contacts and could perform the function more than once. To avoid multiple responses, you merely configure the "de-bounce time" when you configure the limit switch Soft-Device. Generally a time of 25 milliseconds will allow the contacts to settle. When you have finished the configuration, merely submit your choices and then test the button on the Soft-Device page. What could be simpler?
Technical Specifications
Each limit switch is connected to the Soft-I/O module with two wires—the module supplies switch power, and that simplifies wiring.
Non-volatile, user-configurable parameters include: Soft-I/O module supplied 24 V or 5 V power selection; normally open or normally closed switch sensing and state naming; switch debounce time; and Soft-I/O pin assignments. IMPORTANT SAFETY NOTE: All limit switches must be electrically configured to unilaterally remove power from potentially dangerous circuits. Limit switches are connected to programmable control systems, such as Soft-I/O for information only.
