2.4.2 STG/IN8-S and STG/OUT16-S module addressing
STG/IN8-S and STG/OUT16-S 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 1). See the summary
table in para. X for the maximum number of connectable modules to the central unit. 1)
INTRODUCTION.
Each module must have univocal address in the system. Dual addresses are not permitted
even if modules are on different serial buses.
If the two switches are positioned as above, RSW2 on 0 and RSW1 on D, the
corresponding address in decimals is 13 (see table 1)
