K108 Process Controller 
(K108CtrlLite)
(freeware)

The DIY/Kitsrus Kit 108 is a general-purpose relay board, having 8 relay outputs and 4 digital inputs. It has a fairly simple command set, and uses serial communications for talking to a pc.  There is software supplied with the kit -- it's quite powerful, but complicated and not too friendly.  

K108CtrlLite is designed to provide general purpose control and monitoring functions for the K108 board. Note that it is not intended to be an exact replacement for the software supplied with the K108.  
  
This version replaces the original K108CtrlLite and K108CtrlPro softwares. It has the same functionality as the old K108CtrlPro software, but makes use of a user-configurable diagram for the visual interface, rather than a fixed instrument-type interface. A default diagram is included. New diagrams would be created in the Diagram Editor (a separate download). 

Process Diagrams
A Process Diagram (aka P&ID) presents a symbolic map of a control system or process. This could be a power grid, an irrigation system, temperature monitoring and control in a building, a security system, and so on. Having a visual map/diagram can help make a process more understandable. 
  
    

Software features:   - Relay Control by Input        - each of the 4 K108 Inputs can be configured to link to any            combination of relays.    - Timed Relay Control        - relay "events" can be scheduled at predetermined times.        - any combination of relays        - maximum frequency for scheduled events is once per minute    - Manual Relay Control        - each relay can be individually toggled        - there are 4 Pushbutton Switches that can each be configured            to link to any combination of relays. Each Switch can be set            to be momentary or latching.        - there are 3 "global" buttons (All On, All Off, Toggle All) that can            be used to test general operation of the relays.    - Logging of all actions, complete with date and time        - option to save to file every 24 hrs, or when the program closes.        - viewer utility for looking at saved log files    - Option to auto connect at program start    - Option to define "Start" and "Stop" relay states.    - Diagram interface        - Visual indication of Relay status, Input and Switch events.        - User-configurable labels for Relays, Inputs and Switches        - Create a diagram that suits the user’s environment            (use the Diagram Editor, which is a separate download)            (a default diagram is provided)    - User-configurable label in the application Titlebar area    - Configuration settings and scheduling info are stored in a database.

Change Log   

Sep 05/09  
v. 2.0.1 (17) 
  - core functionality is based on original K108CtrlPro
  - revised visual interface to use a user-designed diagram
  - configuration revised to work with diagram 
  - name change to K108CtrlLite
  - Help file updated

Apr 10/09 
v. 1.0.2.1 (48) 
  - Coding changes to improve reliability of sending commands to 
      the board. 
  - The database file (for scheduling and config) is now embedded 
      in the application (exe file). The program now checks for 
      the existence of the Data and Log folders at startup, creates 
      them if necessary, and loads a copy of the db file into the 
      Data folder. 

Feb 02/08 
v. 1.0.1.2 (45)
  - fixed problem with making a backup of the mdb file

Jan 16/08 
v. 1.0.1.1 (44)
  - Added color config options for the Custom Label and Friendly Names. 
  - Modified Database to accommodate new config options.
  - Internal changes in preparation for "Internationalizing" the program. 
      A consequence of this is many visual changes (most obvious with buttons and fonts). 
  - No changes or additions to basic functionality. 

Notes: 
a. See the Help file re load capabilities of the K108 board.
