The Soft-I/O Light Tower Soft-Device provides flexible, easily configured, high-capability control of a user-supplied light tower. Like all Soft-Devices, it is simply configured using a PC with web browser—no programming. It is easily integrated with existing or new machine designs, and can readily share a single Soft-I/O module with other Soft-Devices.
Soft-I/O Light Tower Soft-Device hardware interfaces include:
- 1 to 5 digital outputs for lights;
- a digital output for a buzzer;
- an analog input to set flash rate;
- a digital input for operator alarm acknowledgement; and
- up to 3 digital inputs to receive up to 8 machine states.
The Light Tower Soft-Device network interface handles the host commands to: 
- set the light tower state (of up to 8 states);
- read the current light tower state;
- set the acknowledge state;
- set the timeouts for each individual state;
- read the acknowledge state;
- read the flash rate (analog value);
- set the flash rate and duty cycle for a light or buzzer; and
- read the flash rate for a light or buzzer.
The image below displays the setup screen for one of the states. Reference the Light Tower Soft-Device data sheet for further information.
