K108 Controller Standard (K108CtrlStd)
(suitable for use on Win10 tablets)

The K108 Relay board from DIY/Kitsrus (www.kitsrus.com) features 8 computer-controlled relay channels, plus 4 digital (on/off) type input ports. This software provides general purpose control and monitoring functions for the K108 board.
Software features:
 - Relay Control by Inputs
     - each of the 4 K108 Inputs can be configured to link to a relay.
 - Relay Control by Manual action
    - 4 Pushbutton Switches that can each be configured to link to 
        a relay. Each Switch can be set to be Momentary or Latching.
    - relay indicators on form can be configured to act as pushbuttons,
        which allows each relay to be individually toggled.
    - 3 "global" buttons (All On, All Off, Toggle All) that can
        be used to test general operation of the relays.
 - Relay Control by Schedule
    - relay "events" can be scheduled at predetermined times.
    - any combination of relays
    - maximum frequency for scheduled events is once per minute
 - Logging
    - overall relay status is logged once per minute, 
       complete with date and time
    - scheduled relay events are recorded as they happen
    - Switch and Input events are recorded as they happen
    - option to autosave to file every 24 hrs, 
        or to manually save as desired
 - Configuration settings and scheduling info exist 
        only during program runtime.
