  • Page 21: Nim Block Diagram

    NIM Block Diagram Figure 2-1 is a simplified block diagram of the Series 500 NIM. The media interface blocks are intentionally left unlabeled because the type of media interface depends on which NIM model you are using. The blocks are described as follows.

  • Page 22: Timimg Considerations

    TIWAY I Network Configuration (continued) The basic difference in the NIM models is the configuration of the media interface cards. Examples of the possible application of the different models are as follows: If you want media redundancy for a dedicated line (lease-line) modem, or an RF (short-haul) modem, use PPX:500–5040 which supports RS-232-C/423 on both Port A and Port B.

  • Page 23: Rs-232-C Cable Installation

    RS-232-C Cable Installation The physical layer in TIWAY I provides a modem interface for synchronous or asynchronous modems at data transmission rates up to 115.2K bits per second. The modem interface provides standard signals, as defined in Table 2-1, for control of two-way alternate data transmission using both half and full duplex modems.

  • Page 24: Pin Assignments Of Local Line Connectors

    Local Line Cable Installation The following paragraphs describe Local Line characteristics and installation guidelines. Local Line The TIWAY I Local Line is a physical signaling technique (baseband, Characteristics differential current drive) which operates over shielded, twisted-pair cabling. The Local Line cable may be up to 25,000 feet long, depending on loading and baud rate selection.

  • Page 25: Network Cable

    Network Cable The TIWAY I local line network cable consists of a main cable or spine with droplines or taps for each Secondary. Interrelated network variables having direct influence upon network performance are: Maximum trunk cable length Cable type Tap length Tap spacing Number of Secondaries Maximum baud rates...

  • Page 31: Cable Routing

    Local Line Cable Installation (continued) Cable Routing Cable routing should be planned as if the path between all stations on the network were free of obstructions. Next, modify the first routing to account for obstructions, then calculate the amount of cable needed. CAUTION All local and national electrical and fire codes should be observed when installing wiring.

  • Page 32: Obstructions

    Surface Duct Routing. Surface ducting for network cabling is usually installed along the baseboards or is attached to walls at desktop height. While surface ducting protects cables from both physical and EMI effects, it may also require that network computing devices be positioned near a wall. Obstructions Aside from physical obstructions such as posts, walls, and partitions, electrical interference should also be avoided.

  • Page 33: Local Line Biasing

    Local Line Biasing The TIWAY I Local Line is designed to operate with shielded, twisted-pair cable which has a characteristic impedance of 124 ohms. In certain network configurations, the Local Line must be biased to raise its noise immunity and to prevent oscillations of receivers connected to the line. In all configurations, the Local Line must be properly terminated at both ends of the trunk to prevent an impedance mismatch which could result in signal reflections on the line.

  • Page 34: Terminating The Local Line

    Turn on the bias switch on the unused port to prevent the entry of noise into the NIM. Terminating the The Siemens Local Line must be properly terminated at both ends of the Local Line trunk to prevent a possible impedance mismatch which could result in signal reflections back along the line.

  • Page 35: Terminating The Local Line

    Switch, the bias switch should be moved downward to the ON position. Figure 2-6 Terminating the Local Line NOTE: All Siemens tap housings contain factory-installed terminating resistors. If the Tap Housing is not used to terminate the Local Line, the terminating resistors must be removed when the output cable is attached.

  • Page 38: Installing The Nim

    Installing the NIM This section describes how to mount the NIM in the Series 500 I/O base, connect the communication cables to the NIM, and initialize the system for operation. The programmable controller (P/C) and the programming device should be in place before you install a NIM. Before inserting the NIM into the I/O base, first determine which two adjacent slots that the NIM will occupy.

  • Page 39: Inserting The Module Into The Base

    Inserting the Module into the Base Before using the module, you should decide whether you want to protect it by “keying” the module’s position in the I/O base. As shown in Figure 3-1, keying is accomplished by placing the three keys provided in the right-hand slot of the two slots occupied by the module so that they fit into the notches on the module edge card.

  • Page 40: Installing The Nim In The I/O Base

    Once the keys are in place, orient the module so that the indicators are on the top half of the module. Then, carefully push the module into the I/O base as shown in Figure 3-2. When the module is fully seated in the I/O base, tabs will hold the module in place.

  • Page 41: Setting The Dipswitches

    Setting the Dipswitches As Figure 3-3 illustrates, there are two blocks of dipswitches on the Series 500 NIM. The lower block of eight switches is used to select the NIM’s address on the network. The upper block of ten switches is used to configure the network communication parameters.

  • Page 42: Selecting Network Configuration Parameters

    There are two physical Parameters media types over which TIWAY I communication can occur: Siemens Local Line and RS-232-C. Several dipswitches on the configuration switch block are ignored when operating on the Local Line media. These switches are noted in the following descriptions.

    Setting the Dipswitches (continued) Figure 3-3 NIM Switches and LEDs Installation SIMATIC TIWAY I Series 500 NIM User Manual...

  • Page 44: Network Data Rate Switch Settings

    Configuration switches 1 through 4 (on the configuration switch bank) select the data transmission rate. All devices on the network must be configured to communicate at the same data rate. The data rates corresponding to the switch settings are shown in Table 3-3. For synchronous operation in RS-232-C communication, the rate of data transmission is established by the modem.
  • Page 45 Setting the Dipswitches (continued) Synchronous/Asynchronous Selection. Configuration switch 5 selects synchronous or asynchronous operation for modems. For synchronous modem communication, the NIM receives the transmit and receive timing signals from the modem via transmit signal timing element (DB), and receive signal timing element (DD). If the modem data rate does not match a TIWAY data rate exactly, the data rate select switches should be set to a rate that is the next lower data rate from the modem For example, if a 56,000 bps synchronous modem is used, a data rate of 38,400 bps should be...

  • Page 46: Other Switches

    Lockout/Enable. Configuration switch 9 enables the P/C to “lockout” the NIM during time-critical operations. This function is not needed normally. During lockout, the NIM will not communicate with the P/C. The actual mechanism is as follows: The P/C “sees” the NIM as an 8 channel discrete output module on the I/O portion of the scan.
  • Page 47 Setting the Dipswitches (continued) A successful completion of these tests will leave only the NIM GOOD and PC/NIM COMM GOOD indicators on. If the TEST LED remains on, run the User Initiated Self-Test to determine the source of the error. The reset switch should always be pressed after you change the configuration or address selection dipswitches.
  • Page 48 Local/Remote. When set to remote, this two-position switch enables the NIM to perform write operations to controller memory. In the local position, the NIM cannot write to the controller. In either position, the NIM can monitor P/C memory and mode of operation. The Local Mode will be indicated (after the NIM is brought into the online state) by a flashing Online LED indicator.

  • Page 49: Series 500 Nim Self Tests

    Series 500 NIM Self Tests The three levels of Series 500 NIM self tests available in the NIM are described in the following paragraphs. They are: Power-Up Self-Test Run-Time Self-Test User-Initiated Self-Test Power-up Self-Test The Series 500 executes a Power Up Self-Test in the following cases: Immediately following the application of +5VDC from the I/O base (power-up) as part of its initialization Any time the Reset switch is pressed (See Figure 3-3)

  • Page 50: User-Initiated Self-Test

    Failures detected in the ROM integrity test will cause the NIM GOOD LED to extinguish, and force the NIM into a failed state. In this condition the NIM goes to the Logically Disconnected State (LDS) and will always issue a Disconnect Mode (DM) response to any commands received.
  • Page 51 Series 500 NIM Self Tests (continued) Start of execution of the User-Initiated Self-Test will be signaled by the illumination of the Test Mode LED, with all other LED indicators being extinguished. Then, after approximately ten seconds, all LED indicators will flash on and off for approximately two seconds.

    Connecting the Network Cables Network cabling should already be in place before NIM installation is begun. If you need information concerning network cabling, see the SIMATIC TIWAY I Systems Manual (TIWAY–8101). There are two communication ports on the Series 500 NIM, one on the top of the module (Port A) and one on the bottom (Port B).

  • Page 55: Tiway I Primitives

    TIWAY I Primitives Primitives are high-level commands that allow a user to access like data types in all different Secondaries in the same manner. For example, a Primary can access image register memory in a NIM-equipped 520, 530, 5TI, and PM550 controller with the same command. The purpose of the Primitives is to remove as many differences as possible between the controllers, so that applications programs at the Primary level may treat all TIWAY I Secondaries in the same manner.

  • Page 56: Primitive Functions

    Primitive Functions Primitives serve as the command structure that a TIWAY I Primary uses to access (read or write) information in a TIWAY I Secondary. The Primitives defined in the following paragraphs serve these basic functional needs: To access and retrieve data To ascertain the status and configuration of attached devices To perform control operations on the attached device SIMATIC TIWAY I Series 500 NIM User Manual...

  • Page 57: Primitive Structure And Operation

    Primitive Structure and Operation A Primitive consists of multiple fields that specify the Primitive’s length and function, type and location of data to be accessed, and data to be transferred. In TIWAY I, a Primitive forms the information field of an HDLC Information frame (I) or Unnumbered Information frame (UI) if HDLC operation is selected.

  • Page 58: Basic Primitive Structure

    Figure 4-1 illustrates the basic Primitive structure when HDLC operation is selected. There is a Request Format and a Response Format, as shown. The binary weight of the fields is detailed in Figure 4-2. All field lengths are multiples of 8 bits, which allows for octet testing of data link frames at the data link/media access control layer.

  • Page 120: Local Line Length

    Local Line Length The PM550 CIM supports operation over the Local Line at distances up to 10,000 feet and 9600 baud. Advances in technology have provided line drivers and receivers that support Local Line operation up to 25,000 feet. These new drivers have been incorporated in TIWAY I Conformant devices to support the extended operation.

  • Page 121: Local Line Bias And Termination

    Bias Switch. The CIM is provided with a jumper which allows selection of bias or no bias. The Siemens Local Line must be properly terminated at both ends of the trunk to prevent a possible impedance mismatch that could result in signal reflections back along the line.

  • Page 122: Local Line Bias And Termination

    If more than one CIM is attached to a Local Line, place CIMs at the extreme ends of the Local Line trunk. Install the jumpers provided with the outermost CIMs in accordance with the instructions in the PM550 CIM User’s Manual, Manual Number PM550–1101154–4. This will apply the correct bias to the Local Line to prevent oscillations of the CIM receivers.

  • Page 124: B.1 Introduction

    Introduction The Series 500 NIM allows IBMr excess 64 and IEEE representation of floating point data types (noted in Chapter 4). Floating point formats consist of three parts: the sign bit, the exponent, and the mantissa, or fraction. For both the IBM and the IEEE formats, the sign bit indicates the positive or negative value of the mantissa.

  • Page 125: B.2 Ibm Format

    IBM Format Floating point numbers are stored in memory in two 16-bit words as illustrated in Figure B-1. Before being stored in memory, however, the number is converted to a normalized hexadecimal fraction, a corresponding hexadecimal exponent, and a sign bit. The fraction portion of the IBM number is normalized;...
