Schloms Process Interface (SPI)
Inputs can be realized in 3 different ways:

1. By additional sensors (pressure/temperature/flow)

2. If analog inputs/sensors
(pressure /temperature, flow rate,…) are already installed, electronic signal duplicators are used to feed the SPI

3. New systems may have Modbus system; these signals are used straight into the system/databank via LAN for further evaluation
