Chapter 1 Introduction
Board ID Setting
The PCIE-1756H has a built-in DIP switch that defines each card’s ID when multiple
cards have been installed in the same PC chassis. The board ID setting function is
very useful when users build systems with multiple PCIE-1756H cards. With correct
Board ID settings, you can easily identify and access each card during hardware con-
figuration and software programming.
Channel-Freeze Function
The PCIE-1756H provides Channel-Freeze function, which can be enabled either in
dry contact or wet contact mode (selectable by the on-board jumper). When the
Channel-Freeze function is enabled, the last status of each digital output channel will
be safely kept for emergency use. Moreover, you can enable this function through
software as it is useful in software simulation and testing programs.
Reset Protection
When the system has undergone a hot reset (i.e., without turning off the system
power), the PCIE-1756H can either retain output values of each channel, or return to
its default configuration as open status, depending on its on-board jumper setting.
This function protects the system from wrong operations during unexpected system
resets.
All these merits make PCIE-1756H an excellent choice for industrial applications.
1.3 Applications
Industrial ON/OFF control
Switch status sensing
BCD interfacing
Digital I/O control
