STB Distributed I/O
Solution 0
Configuration and debugging software
For applications requiring short response times (< 3 ms), the Advantys STB
Distributed I/O Solution allows you to create reflex functions using the configuration
and debugging software. The reflex functions work directly at the level of the island
output modules, so that they are not taken into account or processed by the island's
master device. These reflex functions can be associated with “priority” I/O modules
to ensure reliable response times.
An Advantys STB island can call up to 10 reflex functions. These functions are
created from blocks whose inputs are activated by digital or analog input channels
and whose results activate a digital or analog output channel. You can nest two
reflex functions.
Various types of function blocks are available:
Documentation: A “Reflex actions” document is supplied on the CD-ROM
STB SUS 8800 and on our website www.us.telemecanique.com.
