1.3 Product Configuration
Figure 1 - Product Configuration Block Diagram - shows how the digital I/O boards may be
connected to form a variety of systems, by using the supplied cables. The simplest system
configuration comprises one board (either PCI215 or PCI272), a 78 way cable and an EX233.
This system provides user terminals to all I/O functions of the board. More complex,
configurable systems include isolated or common ground input and output at low or high level.
These boards employ the concept of I/O Groups, where a group can be six 16 bit counter timers
with interconnects, or 24 lines of digital input/output. These groups are integrated as necessary
to provide the specified functionality.
A clock source group provides five precise frequencies for counter/timer input. The PCI215 has
software configurable clock and gate source groups.
The user I/O connector map recognises this grouping and allows any combination of expansion
panels to be directly added to any of the boards, with each panel mapped onto a counter/timer
group or digital I/O group.
