This paper deals with an example of a mutual communication
solution between all of the components in a robot flexible
integrated manufacturing system. This issue is complicated and it
requires an individual approach, which depends on system
flexibility. The typical solution of signal communication flow,
based on binary outputs, is simple, easy to use and it doesn’t
require logical reorganization in algorithm to steering system. It
happens so because of the solution simplicity. Unfortunately,
using binary data exchange solution makes complicated tasks
realization impossible through individual objects of robot
integrated manufacturing system. Using advanced information
exchange technology, based on industrial LAN, e.g. PROFIBUS
DP, decreases the information sending incompatibility between all
objects of robot integrated manufacturing system. It is also
possible to use PROFIBUS DP to initialise the supportive
operation and sending machining program or only its part to direct
numerical computer DNC. To use all possible of LAN
connections, it is necessary to change the steering system
algorithm, in order to add another object (lathe) to manufacturing
center.
