Option
Description
MODBUS,
fast
For MODBUS applications. The SPA-2 stays in normal mode. This option permits
high data transmission rates, but increases power consumption.
MODBUS,
slow
For MODBUS applications. The SPA-2 goes into idle mode and can be woken up by a
command via the RS-485 interface with a low baud rate. This option reduces power
consumption at lower data transmission rates.
Standard
(default)
The SPA-2 goes into sleep mode and can be woken up by a command via the RS-485
interface only with a time delay. Option with the lowest power consumption.
F-D Warm-up time
The time between the power-supply is switched on and the first measurement.

Sommer ID
The Sommer ID is used to define stations within the Commander software. The ID is preset in the
device and corresponds to its serial number.SOMMER suggests not to change the ID, except if a
SPA-2 device is replaced. In such a case it can be practical to change the ID of the new device to the
ID of the replaced device to guarantee data consistency.
