Introduction

PCI-1751 is a 48-bit digital I/O card for the PCI bus. Its 48 bits are divided into six 8-bit I/O ports and users can conﬁgure each port as input or output via software. The PCI-1751

also provides one event counter and two 16-bit timers, which can be cascaded to become a 32-bit timer.

Fulﬁlling the True Requirements of Industrial Applications

With two practical functions, the PCI-1751 fulﬁlls the true requirements of industrial applications. When the system is hot reset, (power is not shut off), the PCI-1751 can either

retain the last I/O port setting and output value, or reset to its default conﬁguration, depending on jumper settings. This function protects the system from wrong operations during

unexpected system resets. Additionally, the PCI-1751 supports both dry and wet contacts so that it can easily interface with other devices.

Interrupt Handling Capability

Two lines in each I/O port (C0 and C4) and two of the three counter outputs (Timer 1 and Counter 2) are connected to the interrupt circuitry. Two interrupt request signals can be

generated at the same time and the software can service the two request signals by ISR. Moreover, a pin in the connector can output a digital signal simultaneously with the card

generating an interrupt, and users can utilize this function to trigger external devices with the interrupt.
