    The IMFEC11 High Level Analog Input (FEC) module inputs 15 channels of analog or frequency shift keyed (FSK) digital sig- nals to the MFP or MFC module. The IMFEC11 module per- forms all the functions of the IMFEC12 module and also provides communication with the Bailey-Fischer &...

  • Page 11: Hardware Application

    HARDWARE APPLICATION The FEC module interfaces analog and digital signals from field devices to the MFP or MFC module. The IMFEC11 module can interface Bailey-Fischer & Porter FSK smart transmitters and other smart devices. The IMFEC12 is for use with conventional transmitters (BC, EQ and PT) and standard analog inputs.

  • Page 12: Features

    INTRODUCTION In the FSK analog point-to-point mode, the IMFEC11 module can interface up to 15 discrete analog process inputs from FSK smart devices and communicate (digitally) with those devices. Additionally, the IMFEC11 module can interface a mixture of conventional transmitters and other external analog inputs while operating in this mode.

    FEC module. FUNCTIONAL OPERATION The FEC module can be divided into four functional blocks for the IMFEC12 and five functional blocks for the IMFEC11. Figure shows a block diagram of the IMFEC1 Analog Input (FEC) module.

  • Page 20: Microprocessor And Control Logic Circuitry

    Module Input/Output Circuitry Process inputs to the IMFEC11/12 modules can be standard analog signals of four to 20 milliamps and ±10 VDC; or analog (point-to-point) or frequency shift keyed digital signals (on a field bus) (IMFEC11).

  • Page 21: Analog Inputs (Point-To-Point Mode)

    On-board jumpers on the IMFEC11 set the operating mode. NOTE: In field bus mode, the IMFEC11 module can handle up to 15 transmitters. The Type STT03 terminal can program a maximum of eight transmitters on a single field bus. Refer to the Smart Trans- mitter Terminal, Type STT03 instruction for more information (Table 1-2).

  • Page 22: Fsk Inputs (Field Bus Mode) Imfec11 Only

    DESCRIPTION AND OPERATION FSK INPUTS (FIELD BUS MODE) IMFEC11 ONLY For IMFEC11 modules in the field bus mode, all data and com- munication are FSK encoded digital signals on a shared bus and require decoding. The microprocessor can read any input by specifying the bus address of the device.

  • Page 24: Communication Circuitry (Imfec11 Only)

    DESCRIPTION AND OPERATION Communication Circuitry (IMFEC11 only) The IMFEC11 module can use FSK digital communication in the field bus mode or point-to-point mode. When the micropro- cessor enables the FSK receive gate, digital signals from an FSK style smart transmitter enter the FSK communication cir- cuitry.

  • Page 25: Fsk Operation (Imfec11 Only)

    Figure 2-5. FSK Signal and Decoded Digital Equivalent FSK OPERATION (IMFEC11 ONLY) The digital interface, made up of the IMFEC11 module and the controlling module, provides a communication path between an INFI 90 OPEN operator interface and Bailey-Fischer & Por- ter smart transmitters as shown in Figure 2-6.

  • Page 26: Fsk Modes Of Operation (Imfec11 Only)

    FSK MODES OF OPERATION (IMFEC11 ONLY) The IMFEC11 module has two operating modes: FSK field bus mode and FSK analog point-to-point mode. Mode selection is through FEC circuit board jumpers (J2 through J4). Function code 132 must be configured in the MFP or MFC device for every five analog inputs.

  • Page 27: Fsk Analog Point-To-Point Mode

    DESCRIPTION AND OPERATION ® Bailey-Fischer & Porter FSK style smart transmitters (Fig. 2-7). In this mode, the analog signal from each smart transmitter goes to an individual input channel (point-to-point). Because the inputs are analog point-to-point, the FEC module can interface any combination of devices while it is in this operat- ing mode.

  • Page 28: Section 3 - Installation

    SECTION 3 - INSTALLATION INTRODUCTION This section explains how to install the IMFEC11/12 high level analog input (FEC) module. Do not proceed with operation until reading, understanding and doing the steps in the order in which they appear. SPECIAL HANDLING Use the static grounding wrist strap when installing and remov- ing modules.

  • Page 29: Unpacking And Inspection

    1. Examine the module to make sure that no damage has occurred in transit. 2. Notify the nearest Elsag Bailey sales office of any damage. 3. File a claim for any damage with the shipping company that handled the shipment.

  • Page 30: Dipswitch And Jumper Settings

    DIPSWITCH AND JUMPER SETTINGS For the IMFEC12 module, there is one dipswitch (S1, Fig. is the same for both the IMFEC11 and the IMFEC12) that must be set before installing the module. The single dipswitch sets the I/O expander bus address.

    J6 through J20 and Table for jumper descriptions. If installing the IMFEC11 module in the field bus mode, the NTFB01 Field Bus Termination Unit must be used. Refer to Appendix C for information on NTFB01 configuration for field bus termination.

  • Page 33: Installation

    INSTALLATION ® For more information about the termination units or modules, refer to the instructions listed in Table 1-2. Installation The FEC module inserts into a standard INFI 90 OPEN module mounting unit (MMU) and occupies one slot. To install: 1.

  • Page 34: Section 4 - Operating Procedures

    When the IMFEC11 module detects a channel that is set up for a smart transmitter (a configuration containing function codes 132 and 133), it does a check of that channel. It reads the actual configuration of the smart transmitter and compares it to the configuration within the controlling module.

  • Page 35: Operation

    (reset) of the MFP or FEC module may be required for changes to take effect. For IMFEC11 modules, smart transmitter parameters can be viewed or modified using the handheld Type STT02/03 smart transmitter terminal. View only is possible when the FEC mod- ule is present and the FEC channel is on-line.

  • Page 36: Status Led

    OPERATING PROCEDURES STATUS LEDS The IMFEC1 module has two LEDs (red/green) on its face- plate that indicate module status. Figure shows the loca- tion of the status LEDs on the FEC faceplate. Refer to Table for a list of LED states and their meaning. B a iley IMFEC12 STATUS LED...

  • Page 39: Missing I/O Module Error

    TROUBLESHOOTING Missing I/O Module Error A missing I/O module error (no FEC response or wrong type) occurs when the IMFEC1 address (set by dipswitch S1 on the module) does not match the I/O module address in the control module configuration (function code 132). This error appears in the status bytes of the control module (bytes three through five).
