Google Translate says "Hello everyone, I have in the factory an IRB 1400 M94A S4 controller, what software do you recommend for the simulation?"
The software for an M94A IRB1400, depending on the CPU boards, could be CommWare 2.0, BaseWare 2.1, or BaseWare 3.0.
If you use RobotStudio only for simulation, you can choose an IRB1400 in the robot library. I think the reach is the same no matter the model year. Please do not attempt to load any files created in RobotStudio into your S4.
