    Analog Measuring (Unity)

    General

    Purpose
    This manual contains a PLC specific description of ACESYS for the Schneider
    Electric Unity controllers. This version of ACESYS for Unity is designed for the
    HMI system ECS.
    This manual has to be seen in consecutive with the generic ACESYS manual.

    Main Program Structure
    It is recommended to create one section for each Analog Measuring object in the
    Structural View:

    Analog
    Section

    Figure 1 Analog Object- Structural View

    Afterwards attached the section to the Functional Section parent section (group or
    route):

    Figure 2 Localization of Analog Object

    The created section will now appears in the Functional View:

    PLC Program Analog Measuring

    Variable Definitions
    One tag of the type “ACESYS_ANALOG_FACEPLATE” has to be created for
    each Analog Measuring object:

    Figure 4 Analog Faceplate Tag

    This tag contains information to/from ECS. Address definition is required for data
    exchange with ECS. For further information about address see chapter Introduction
    section Memory Allocation.

    PLC Program
    Below is shown programming example for one Analog measuring unit:

    Figure 5 PLC Program Examples

    The following steps have to be done after inserting of the ACESYS_ANALOG


    function block and basic input pins are linked:
    1. Link the DEPT_CMD from the parent department object
    2. Link the raw analog input in Real format to the input PIW for indication
    on faceplate
    3. Link the analog input normalized to 0.0-100.0 in real format to the input
    PIW_NORM
    4. Assign U_RANGE, O_RANGE and SIG_FAULT to healthy default values
    (“1”) if no error check is possible. Another possibility is to link status from
    I/O-card or insert compare instructions to trig fault states above/below a
    certain analog value.
    5. Link the variable for faceplate parameters
    6. Link the token variable from parent object (group or route)
    7. Link the Machine Status Word (MSW) variable. The index has to be
    unique for each Analog function block

    ECS Analog Measuring Configuration

    Analog A-point Algorithms


    Create an A-Point using the following Interface type, Conversion Algorithm and
    Block algorithm:

    Conversion Algorithm: 1 – Linear input


    p= C1*aiv + C2
    C1 = Gain
    C2 = Offset

    For further information about Reference points see the ECS document
    “ApointAlgorithms30_English.doc”.

    Click at the icon to setup the Modicon Addresses.

    Analog A-point Addresses
    The following snapshots illustrate the Modicon address configuration in ECS. The
    addresses refer to the memory layout suggested in chapter Introduction section
    Memory Allocation:
    Unit = 1:

    Register = 3997 + Unit * 4

    Register = 12141 + Unit * 60

    Figure 6 Analog Address Configuration Unit no. 1

    Unit = 4:

    Register = 3997 + Unit * 4

    Register = 12141 + Unit * 60

    Info Faceplate
    The following faceplate can be called up from the Analog faceplate:

    Figure 8 Analog Info Faceplate

    ACESYS Version and Build Number indicate the version of the PLC function
    block.

    Program State expresses the current state of the function for debugging purposes.
