3.1 ALIEM (Alpha-Log Input Extension Module)
ALIEM is a module used to extend the number of sensors managed by Alpha-log. It measures the instant
values from the sensors connected (it does not perform any statistical processing) and makes them available
to Alpha-Log through the Modbus RTU protocol on the RS-232 port (3).
ALIEM looks like in Fig. 3.
