12 Chapter 7 Programming The Model 7026 is a PXI register based card assembly designed for use with the National Instruments PXI specification. You can program the Model 7026 in 8, 16 or 32 bit wide data format. By way of your PXI controller, you can write the data to the appropriate register, shown on the register map, for the relay or relays in the register that is being closed. When the data bit is true, the relay chosen is closed. You can determine relay state in a register by simply reading the desired register. Data read back represents the value of the desired register. In addition, you can read back the coil state to verify that the coil is driven correctly by the program register. This scenario verifies that the program register has correctly controlled the relay coil. A register map can be organized to show the relay designation at each register, followed by the register s functionality and the path connections to the front panel. PXI automatically assigns the starting address of the card, called Bar0. Bar0 becomes the starting address of the first register. Each address location controls 8 bits. The control functions using 16 format are shown in the illustration below. Programming of the Model 7026 is very straight forward. The module is organized as a 1x32, two wire, 2 amp general purpose relay board. The location of the first register is assigned by the PCI enumerator. This is designated as "Bar0" or the starting address of the card. The program registers using 16 bit format are located as follows: Register #1 : read/write function address = Bar h coil read back address = Bar h BIT RELAY K16 K15 K14 K13 K12 K11 K10 K09 K08 K07 K06 K05 K04 K03 K02 K01 Register #2 : read/write function address = Bar h coil read back address = Bar Ah BIT RELAY K32 K31 K30 K29 K28 K27 K26 K25 K24 K23 K22 K21 K20 K19 K18 K17 Page 12
