Data Transfer between Test Bed and PUMA Open System

1.4 Data Transfer between Test Bed and PUMA
Open System
At the PUMA Open system, demand values are calculated and trans-
ferred to the output modules. At the F-FEM-DAC, the digital demand
values are converted into analog quantities (current/voltage) again,
e.g. to control a throttle actuator.

Fig. 3 Data transfer between test bed and PUMA Open system
1 PUMA Open PC
2 IEEE 1394 PC board PCI, via which all signals of the F-FEM
modules are transferred to/from the PUMA Open system.
3 F-FEM-DAC – digital-to-analog conversion and output of the
demand values
4 Engine test bed – analog signals (speed, torque, etc.) are
output using actuators fixed at/in the engine.
