STG/IN8S and STG/OUT16S module addressing
STG/IN8S and STG/OUT16S modules are addressed using the two rotary switches in RSW 1
and 2 hexadecimals. Rotary switches permit hexadecimal settings (base 16). Each switch as
16 positions (0-F) and the pointer is positioned on the number chosen using a screwdriver
to create a decimal value between 1 and 255 (see table below). See the summary table 1 for
the maximum number of connectable modules to the gas control unit.
Each module must have univocal address in the system. Dual addresses are not permitted
even if modules are on different serial buses.
Figure 17) Example: If the address switches are set in this mode, RSW2 at 0 and RSW1 at D, the corresponding address in decimal numbers would
be 13 (see table below).
Table 6) Conversion from decimal to hexadecimal numbers. (*) Addresses not available for the Modbus protocol, (**) Address not available for
the Galileo protocol
