The only hardware required is a Speedgoat target machine to simulate the behavior of the plant, the environmental conditions, and all interfaces to which the PLC is connected. This setup enables the user to test the PLC algorithm for a wide range of functions, in various states, and under nearly all possible conditions.
Hardware-in-the-loop simulation with Speedgoat target machines causes the PLC to behave as if connected to the real plant. This allows testing of the PLC software and the physical connections of the final hardware with network slave devices such as motor controllers, sensors, I/O couplers, or robots.
