• PLC/PAC System Integration (TC39P)

    Length: 5 days
    CEU Credits: 3.5


    What type of PLC/PAC system do I choose? The PLC/PACs system is provides three major subsections: (1) PLC/PAC hardware/software, (2) graphics and (3) communications. This course will explore all three areas and drill down to various options. In addition, how personal computers are being used as PAC front ends and I/O is being connected will be covered. You will develop possible system requirement questions for various PLC/PAC vendors prior to the time of the implementation project. You will also be able to choose the proper programming language(s) to fit your system (RLD, ST, FBD, IL and/or SFC).

    You will be able to:

    • Introduction:  Scary Stories - Accident Evaluation - Justification
    • Definition of SIS and its Functions:  Dormant - Separation - De-energize to trip - Safe Failure Complications
    • Components:  Processors - Sensors - Final Elements
    • Layers of Protection:  Separation and Probability Factors - Statistical Tools
    • Hazard and Risk Management:  Hazard Identification - The Safety Life Cycle - Basic equations and their origin
    • Failure Rates & Modes:  Definition of PFD/PFS - Availability
    • Systems:  Role of redundancy - Output protection - Diagnostics - Safe Failure Fraction - Hardware Fault Tolerance
    • Safety Standards and Certifications

    You will cover:

    • Basic components of a PLC/PACs system
    • Special considerations in choosing a system
    • CPU and I/O hardware configuration and addressing
    • Basics of graphics
    • Basics of various communication protocols and where to use them
    • The IEC 6-1131-3 specification for programming different languages used in PLC/PAC systems (structured text, relay ladder diagram, function block design, instruction list, sequential function chart's)
    • Programming in RLD, to include interlocking and timers/counters
    • Wiring a complete system, to include, the discrete and analog I/O
    • System installation guidelines
    • System wiring checkout
    • Possible questions to ask your vendor while developing system requirements
    • Economic trade-off considerations between DCS, PLC and PAC systems

    Classroom/Laboratory Exercises:

    • Wire a complete digital and analog I/O PLC system to a simulator and do a complete system check out
    • Configure a digital/analog I/O hardware and CPU from a system specification
    • Program, download to PLC and simulate a RLD example
    • Draw and tag basic graphic symbols
    • Set up communications between eight application programs, on a laptop, to a PLC
