High Country Tek DVC80 - Manual (Page 81)

P/N: 021-00154, Rev. A.6 - updated for V4.7 Tools Page | 81
The DVC21 screen is broken up into three areas: Name, MAC ID, and
Individual Input Configuration. The Name is used to uniquely identify a
particular DVC expansion module. The MAC ID tells the DVC10 how to
address the Input Module when communicating over the CAN Bus. You
configure the inputs by pressing the numbered buttons.
Digital Inputs
Digital inputs are Boolean inputs that are either true or false. The input is
enabled when the Name field is specified. The De-bounce Time setting is used
to filter momentary spikes on the input. The Input Polarity determines what
voltage level is interpreted as a true or false or which edge causes a software
toggle. Software toggle changes the state of the program variable when a
rising edge or falling edge is detected on the input.
Note: Regardless of what type of switch is used, the DVC10 will react according
to the voltage seen at the input (above 2.5 volts is a high level and below a low
level). Instructions for hooking up a switch to provide the desired voltage levels can be found in the hardware
manual.
Name:
The name used in the bubble logic screen to access this variable and properties.
Range: 16 Characters with no spaces. Usable characters are A-Z, a-z, 0-9, and "_".
Rules:
The first character cannot be a number.
Compiler Keywords or other Names already in use are not valid.
Debounce Time:
The amount of milliseconds to wait before accepting a change in input states
Range: 0 to 9990ms in 10ms Increments
Polarity:
Polarity has two types of control depending on the state of the software toggle.
When No Toggle and Active High are set, the variable is true when the input is + Voltage.
When No Toggle and Active Low are set, the variable is true when the input is Ground.
When Toggle and Active High are set, the variable changes states on a rising edge.
When Toggle and Active Low are set, the variable changes states on a falling edge.
Range: Active High, and Active Low
Software Toggle:
Toggle reverses the True/False state of a variable. The digital inputs level does not directly set the variables
value; rather, the rising or falling of the digital input will reverse the state of the variable. Software Toggle gives
the programmer more options for controlling an input variable.
When No Toggle and Active High are set, the variable is true when the input is + Voltage.
When No Toggle and Active Low are set, the variable is true when the input is Ground.
When Toggle and Active High are set, the variable changes states on a rising edge.
When Toggle and Active Low are set, the variable changes states on a falling edge.
Range: Toggle, No Toggle
