Advantech’s two new PCI Express DI/O cards, the 48 channel PCIE-1751 and the 96 channel PCIE-1753, both provide 5V/TTL compatible DI/O and counter/timer on the same card, therefore saving the need to buy additional cards in systems that have a limited number of slots. They are capable of performing tasks for many industrial features such as dry and wet contact; digital input filter to filter signal noise and improve data accuracy; pattern match interrupt; change of status interrupt; and additional counter/timer channels.
Through the use of interrupts, the card removes the need for the CPU to continuously check the changes in status and pattern matching, allowing users to optimize system performance.
PCI Express has been available in commercial PC’s for a long time and is becoming more common in industrial machines. Since these PCIE cards use the same underlying bus architecture as PCI, there is no need to redevelop software for transition and users can transfer their legacy systems to the new interface without any inconvenience.
PCI Express cards are configured using the same free universal utility and configuration software, Advantech’s DAQNavi. To help with the development of applications, Advantech provides a range of options such as an SDK which works with: Microsoft Visual Studio .NET including C#, VB, and C++, as well as Delphi. DAQNavi also includes free utilities such as virtual graphic VOM, a data-logger graphically displayed, function testing, documentation and code examples for the SDK.
