  3. Turbine Crane

  4. Walk downs • Review instructions to ensure workable and adequate • Right Parts/materials/tools • Permits • Relevant Operating Experience Turbine Crane

  5. Pre Job Briefs • Understand the Task • Critical Steps identified and OE used AND what actions are being taken in reference to these two areas • Two Minute Drills: • Hazards identified AND what are actions are you taking Turbine Crane

  6. Procedure Use & Adherence • WO / procedure in hand & latest revision • Place keepers being used • Sign steps as you go • Follow & understand steps - STOP if can't or don't Turbine Crane

  7. TURBINE CRANE • Terminal Objective Given references provided by the Instructor, the Plant Electrician will maintain Turbine Building Cranes as demonstrated by achieving a minimum of 80% on a written examination. Turbine Crane

  8. . Multi Stud Tensioner

  9. PRE-JOB BRIEF • Identify Critical Steps • Identify Error Precursors • Worst thing that can happen • Error prevention defenses to be used • Actions to assure proper configuration control Turbine Crane

  10. TURBINE CRANE EO 1.6 Describe the Programming of the Allen Bradley SLC 5/04 Programmable Logic Controller

  11. Software RSLogix 500 • RSLogix software is a Windows ladder logic programming tool for SLC500 processors. This software allows the user to: • Establish Communications with SLC 500 processors. • Display and monitor process data including FAULT Codes • Create and Modify new ladder logic • Configure your I/O modules Turbine Crane

  12. Off-line Computer Operation ***Projects that reside on the hard disc of a computer*** Viewing Projects: • Projects are files that store all of the program logic and data for a single processor. • Example: Turbinecrane.rss Turbine Crane

  14. Turbine.RSS Turbine Crane

  15. Off-line Computer Operation Project Files: DataBase Files • Files that contain information which is not used by the processor and is typically stored in the computer memory only. • Examples: Custom Data Monitors, Trends etc… Turbine Crane

  16. Turbine.RSS Turbine Crane

  17. Off-line Computer Operation Processor Files: • Files that can be modified or monitored from the computer while they are being used by the PLC processor • Examples: Data Files, Program Files, Force Files. Turbine Crane

  18. Turbine.RSS Turbine Crane

  19. Off-line Computer Operation Viewing Ladder Logic: • To view ladder logic, you must first open the project you are interested in. • Next, you are to open the ladder file you are interested in i.e. LAD02 Turbine Crane

  21. On-line Computer Operation ***Using the computer to view or work with a project that is loaded in a SLC 500 processor.*** Online: • The computer must be in continuous communication with the processor to allow the following actions can be performed: • Monitor or modify a project loaded in a processor • Monitor data while it is being collected • Modify data stored in a processor Turbine Crane

  22. Turbine Crane

  23. On-line Computer Operation ***Using the computer to view or work with a project that is loaded in a SLC 500 processor.*** Download: • Transfers a copy of a project from a computer to a processor. *****CAUTION***** Downloading will overwrite the program that is currently installed on the PLC. Turbine Crane

  24. On-line Computer Operation ***Using the computer to view or work with a project that is loaded in a SLC 500 processor.*** Upload: • Transfers a copy of a project from a PLC Processor to the memory of a computer. • Because uploading allows the user to view the actual project that is on the processor, it is commonly used by maintenance personnel to troubleshoot and monitor a project. Turbine Crane

  26. Connecting a Computer and Going On-line • RSLinx software must be loaded and enabled to allow communication between the computer and the processor. • A Communications Driver must be established to allow the software to communicate with the processor. • We will use Data Highway + (DH+) or RS-232 connection typically. • A cable will run from the computer to the Processor to establish the link. • Typically this will either be a RS-232 link or a PCMK (DH+) connection. • A USB to DH+ is also currently available. Turbine Crane

  27. Modes of Operation There are 3 modes of control for the SLC500 processor and they allow different functions to occur. They are selected from a keyswitch on the front of the processor and allow functions to occur as follows: Turbine Crane

  28. Processor Modes RUN – This is the mode you should find the PLC processor in. It allows the processor to perform its intended function and control the crane. • No programming can be performed in this mode. Turbine Crane

  29. Processor Modes PROGRAM – (PROG) When this mode is selected, the operation of the crane will cease. Downloading / Uploading and modification of processor projects can occur. Turbine Crane

  30. Processor Modes REMOTE – (REM) This mode is used to control a processor’s operating mode from the laptop connected to the processor. There are 3 separate modes of remote operation and they must be selected by the computer you have connected. Turbine Crane

  31. Processor Modes REMOTE • Remote RUN – This will allow for crane operation while the computer is connected. • Remote PROGRAM – This is the same as the regular program mode. • Remote TEST – This mode will allow you to run a program from a computer but it will disable the outputs of the PLC.

  36. I : 3 / 10 • I –indicates the Module Type (I- Input) • 3 –indicates the Slot Number • 10–indicates the Terminal Number Memory Layout and System Addresses SLC 500 Hardware Address Characteristics: **Address for a hardware device (input or output) is directly determine by the module slot number and terminal to which the hardware device is wired. Example Address: • I : 3 / 10 • I – indicates the Module Type (I- Input) • 3 – indicates the Slot Number • 10– indicates the Terminal Number Turbine Crane

  45. Hardware to Data Table Relationships Discrete modules • Each I/O module terminal point is represented by a bit in the input or output data tables. • Radix determines the data display available for each digit of a number in a numbering system (i.e. Binary is base 10 and uses a 0 or a 1) Turbine Crane

  47. Turbine Crane

  48. Hardware to Data Table Relationships Analog modules • Will be represented by a Decimal equivalent. • Radix must be changed to Decimal to view the number Turbine Crane
