  • Page 23: Hardware Installation Outline

    2.4 Hardware Installation Outline PCI Configuration PCI cards (or CompactPCI cards) are equipped with plug and play PCI controllers which can request base addresses and interrupts according to the PCI standard. The system BIOS will assign the system resources based on the PCI card configuration registers and system parameters (which are set by the system BIOS).

    7250 and PCI-7251. The PCI-7251 is used as an expansion for the PCI-7250. The operations of the PCI-7251 are the same as that of the PCI-7250. There can be at most 3 PCI-7251 expansion boards to one PCI-7250. Therefore, the PCI-7250 can control up to 32 relays and detect 32 input signals.
  • Page 28 Installation...

  • Page 29: Registers

    Registers Detailed descriptions of the registers are specified in this chapter. This information is useful for programmers who wish to control the card with low-level programming. However, we suggest users fully understand the PCI interface before starting any low-level pro- gramming.

  • Page 30: I/O Address Map

    The following table shows the registers address map, including descriptions and their offset addresses relative to the base address. If the PCI-7251 expansion boards are not installed, corresponding registers have no significance.

    relay is open, the corresponding bit value read is ‘0’. If the relay is closed, the bit value read is ‘1’.

  • Page 33: Operation Theory

    Operation Theory 4.1 Using Relay Output The PCI-7250 contains two types of relays: Form C and Form A. Relays R0 - R3 are form C relays, and R4 - R7 are plain form A type. Note that the cPCI-7252 contains Form C relays only. The differences between these two types of relays are: 1.

  • Page 34: Figure 4-2: Form A Relay

    2. Form A Relay: (R4 - R7) Control Bit = High(1) Control Bit = Low(0) Figure 4-2: Form A Relay Form A relay only has two contacts: NO (Normal Open) and COM (Common). The COM post can make contact either with the NO post or not.

  • Page 35: Using Isolated Input

    4.2 Using Isolated Input The PCI-7250 (or PCI-7251) contains 8 identical opto-isolated control input channels. The circuit diagram of the differential input channel is shown below. Ω 1.2k DInH DInL PC-814 (opto-isolator) Figure 4-3: PCI-7250 Differential Input Circuit The digital input is first routed through a photo-coupler (PC-814), which is shown in the following diagram.
  • Page 36 In addition, a single-pole filter with a time constant of about 5ms is used to filter AC inputs passing through. The normal input voltage range for an active high state is 3 to 24VAC or DC. The normal input range can be extended by chang- ing the resister (Ri) to limit the current (IF) through the PC-814 (opto-isolator to about 10mA).

  • Page 37: C++ Libraries

    C/C++ Libraries This chapter describes the software libraries for operating this card. Only functions in the DOS library and Windows 95 DLL are described. Refer to the PCIS-DASK function reference manual, which is included in the ADLINK CD, for descriptions of Windows 98/NT/2000 DLL functions.

  • Page 38: Data Types

    In order to recognize the difference between the DOS library and Windows 95 library, a capital "W" is placed at the start of each function name Windows drivers. e.g. W_7252_Initial(). Data Types We have defined some data types in the Pci_7250.h (DOS) and Acl_pci.h (Windows 95) header files.

    5.4 725X Initialization @ Description The PCI-7250 and cPCI-7252 cards are initialized according to the card number. Because the PCI-7250 has a PCI bus architecture and meets the plug and play design specification, the IRQ and base_address (pass-through address) are assigned by the system BIOS directly.

    Appendix Relay Contact Protection Circuits The contacts are the most important elements of a relay construc- tion, Contact performance conspicuously influenced by contact material, and voltage and current values applied to the contacts. Another important issue is contact protection; the right contact pro- tection circuit can suppress the counter EMF to a low level.
