I.8.4 Input/output board
o The input/output boar d is ess enti ally made up from:
• section includi ng the microprocess or and the memories that manage
the mac hine control algorithm;
• section dedicated to the interfacing towards the s upervision networ k
and the interfac e panel;
• section dedicated to the inputs/outputs that allow interfacing towards
the devices controlled via a ter minal board with removable c onnectors.
