■ Overview
The PC IO central I/O expansion is a signal input/output module
for the SIMATIC Microbox PC 427B. The I/O mounted into the PC
facilitates particularly fast and realtime-capable measuring, e. g.
with a response time to a digital or analog input within 100 µsec,
for example with pick-and-place machines, robot controls and
filling systems.
This combination offers a powerful control solution to machine,
system and control cabinet manufacturers providing maximum
compactness, high efficiency and flexibility and minimized
costs.
The PC IO is equipped with all drivers for application in
C/C++-based automation solutions with the realtime operating
system RMOS3 as well as applications based on Windows XP
Embedded and XP Professional, e.g. WinAC RTX.
