A CASE STUDY

A system shown in Figure 2 consists of a cell simulator, a PLC emulator, a real robot device, and a
real bar-code reader, etc. By reading the task instruction from a KANBAN with bar-code reader, a
sequence of tasks is performed.
End-users can not only make a program in ladder and/or robot language, but also check a mechanical
motion and a cycle time, etc. in a distributed real simulation environment. Therefore, compared with
the stressful confirmation task in the real world, the user's load was much reduced.

CONCLUSION

In this paper, we proposed a distributed real simulation environment which composed of ORiN system,
soft-wiring system, cell simulation system and ORiN-HLA gateway. By using this simulation
environment, manufacturing system developers are able to use the same simulation model consistently
from a design stage to an implementation stage. A large-scale simulation and a highly accurate
simulation are also achieved. Consequently end-users can perform a lot of tasks in the simulation.
