COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
8 LEDs and address (FLxIO, Sercos III and Modbus TCP)
The drivers COSMOS 3000 are equipped with several status LEDs and with selectors for the field bus address setting.
The LEDs are of different colours and are grouped according to their function, in order to be easily understood; the
number and colour depends on the COSMOS models, according to the integrated field bus.
Also the number of address selectors changes according to the integrated field bus and can vary from 0 to 2.
8.1 Address setting
As you know, the field buses need to identify the devices connected to them in an unequivocal way, in order to ensure a
precise data communication. In COSMOS 3000 equipped with field bus Sercos III, Modbus TCP and FLxIO, the
identification (address) is set by means of rotary selectors installed on the front side.
The address must be unequivocal, otherwise the bus will not operate correctly.
Rotary selectors feature an hexadecimal notation
Here is the decimal-to-hexadecimal conversion table:

If only one selector (ADL) is present, the address will correspond to the number selected by the selector arrow.
If there are two selectors (ADL and ADH), the address will correspond to the number selected by the ADH arrow,
multiplied by 16 and summed up to the number selected by the ADL arrow. Therefore:
Address = ADH*16 + ADL
The address 0 can not be used.
Example 1: ADH set on A, ADL set to 5; the hexadecimal address is A5, the decimal address is 10*16 + 5 = 165
Example 2: ADH set to 7, ADL set on E; the hexadecimal address is 7E, the decimal address is 7*16 + 14 = 126
Example 3: ADH set to 0, ADL set on B; the hexadecimal address is 0B, the decimal address is 0*16 + 11 = 11
