SECTION 4 - PROGRAMMING GUIDE
Here are examples of using the drivers with the 8-bit versions of the 40-296. Other versions operate in the same
way but have a different number of bits in their sub-units.
Using PILPXI
To operate a relay the user could use the simple OpBit command or the WriteSub commands
OpBit
DWORD sub_unit = 1; // Select channel 1
PIL_OpBit( card_num, sub_unit, 1, 1); // Operates bit 1 (A1 resistor relay)
PIL_OpBit( card_num, sub_unit, 2, 1); // Operates bit 2 (A2 resistor relay)
PIL_OpBit( card_num, sub_unit, 9, 1); // Operates bit 9 (B1 resistor relay)
PIL_OpBit( card_num, sub_unit, 10, 1); // Operates bit 10 (B2 resistor relay)
PIL_OpBit( card_num, sub_unit, 11, 1); // Operates bit 11 (B3 resistor relay)
PIL_OpBit( card_num, sub_unit, 12, 1); // Operates bit 12 (B4 resistor relay)
PIL_OpBit( card_num, sub_unit, 13, 1); // Operates bit 13 (B5 resistor relay)
PIL_OpBit( card_num, sub_unit, 14, 1); // Operates bit 14 (B6 resistor relay)
PIL_OpBit( card_num, sub_unit, 1, 0); // Releases bit 1 (A1 resistor relay)
PIL_OpBit( card_num, sub_unit, 2, 0); // Releases bit 2 (A2 resistor relay)
PIL_OpBit( card_num, sub_unit, 9, 0); // Releases bit 9 (B1 resistor relay)
PIL_OpBit( card_num, sub_unit, 10, 0); // Releases bit 10 (B2 resistor relay)
PIL_OpBit( card_num, sub_unit, 11, 0); // Releases bit 11 (B3 resistor relay)
PIL_OpBit( card_num, sub_unit, 12, 0); // Releases bit 12 (B4 resistor relay)
PIL_OpBit( card_num, sub_unit, 13, 0); // Releases bit 13 (B5 resistor relay)
PIL_OpBit( card_num, sub_unit, 14, 0); // Releases bit 14 (B6 resistor relay)
WriteSub
// Sub-unit is 16 bits wide, so 1 DWORD is needed to hold the pattern
DWORD data[1];
data[0] = 0x3F03 // Operates bits 1, 2, 9, 10, 11, 12, 13 and 14
PIL_WriteSub( card_num, sub_unit, data);
data[0] = 0 // Releases all bits of channel
PIL_WriteSub( card_num, sub_unit, data);
