The device has 8 momentary/latching switches for generating output signals. Another switch serves as a release switch. The status is displayed by 9 LEDs. With 4 potentiometers, up to 2 output voltages or 4 input voltages in the range from 0 ... 10 V DC can be set. A selector switch enables the selection of the voltages shown on the display. The connection between the simulation box and the process or the PLC for digital signals is made via a standard plug connection (SysLink). Analog signals are connected via a D-Sub connector. The simulation box is used to display the input and outputs signals of an MPS station or PLC. Two modes of application are possible: – Simulation of inputs for testing of a PLC program. Use I/O data cable (SysLink) (order no. 34031) for this purpose. – Setting of outputs (with separate 24 V supply) in order to operate an MPS station. The cable (order no. 167106, 2.5 m) required for this purpose is included in the scope of delivery. The I/O Interface is a module that interfaces with a computer for data acquisition and PID control of a real process. The I/O Interface provides interconnection between the process devices and the computer. It performs analog signal and digital signal conversions and sends the information to LVProSim, a process control software included with the interface. The I/O Interface has four 4-20 mA analog inputs, two 4-20 mA analog outputs, four 24 V digital inputs, two 24 V digital outputs, and two 30 V dc relays. It connects to a computer through a USB cable and must be powered using a 24 V dc power supply. The I/O Interface requires LVProSim, a free process control software specially designed to connect to the interface and collect data at a fast sampling rate (100 ms). LVProSim has two main features: it can operate as a process controller and a generic process simulator. The I/O Interface can be used with the Process Control Learning Systems and the Industrial Process Learning Systems. Note that, although the I/O Interface is designed to be used with LVProSim, its data acquisition interface is compatible with Linux, MATLAB, and NI LabVIEW. Raw data can be acquired using these software/platform, given the appropriate drivers are installed.
