PLC/Screen Features

• Run screen displays status of Knees, real time position, target position, trouble messages, log breakdown, cant selected, amount of wood left on carriage and many other features.
• Board sizes, Cant sizes, Slabber sizes, Operational limits, Servo dynamic values, servo limits, etc. are entered through the Touch Screen Display and saved in the PLC battery backup ram.
• Help menus for trouble shooting if necessary are on the Touch Screen.
• Some operational features are displayed on the help screens.
• Input/Output status is displayed on the I/O screen.
• ServoSensor status is displayed on screen.
• The Run screen will also show a trouble message if a problem occurs with the system.

System Operation

• Sawing breakdown is determined by the sawyer using a saw line laser as a reference.
• This system can be upgraded with a scan system.
• Cants can be automatically selected by log diameter.
• The operator can easily adapt to the product flow of the mill.
• The operator can back stand cants only, half compute a log, manual or full compute a log.
• When computing a log, the operator selects a nominal cut and the computer will fill the log with as many nominal cuts as possible and will automatically step down to a lesser size cut until the log is full and the minimum opening face limit is met.
• The operator can stack boards for log breakdown, as well as select a cant or multiple cants.
• If the operator enters more boards or cants than the log diameter can handle, the operator can still compute the log and the computer will throw out the last entries.

System Hardware

• The system control cabinets, operator panel, and j-boxes are pre-wired at the factory.
• All cables are labeled and cut pigtails are left at the terminal blocks of each enclosure. Rewiring of the enclosures is expedited because the colored wires and pairs are left as they were when tested at the factory.
• Each enclosure has an identifying placard on the front of it.
• The operator console overlay is reverse engraved, to prevent wear and tear over the years of operation.
• An interconnect cable diagram is provided as well as an installation/operation manual. The manual is written to cover most operational procedures and installation requirements.
