3. Current and resistance parameters for the logical modules
For the safe use of a direct signal connection between control systems in EMCO Concept TURN 155 turning machine and FANUC RJ3iB robot, the input and output characteristics are shown in detail. The parameters of the current – tensional input Table 1.
Statement of input modules in binary information flowing track [1, 2, 4, 9, 10] modules are shown in table 1, whereas table 2 shown the parameters of output modules.
4. FANUC RJ3iB Controller main program algorithm
Because the configuration of the robot lathe center is based on the RJ3iB controller, which is used in that system as a MASTER, there was necessary to show a part of the lathe and robot integration algorithm (Fig. 8).
5. conclusions
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.
