Programmable process images
It is possible, using BICO, to change the functionality of both input and output process
images, with the exception of the CTT2 serial channel present in Slave 1. This serial channel
is required to be present in order that Slave 1 appears correctly on the AS-i network. The
default settings for both single slave and dual slave modes are given in the tables below.
