Setting addresses In order for the digital output cards to be addressed,
each card must be assigned a separate address. The
addresses are assigned with the coding switch on
each card (see Table 3-1 from page 3-8). This
address assigns to each card a special area in the
central unit. The chapter “Operation” from page 3-19
fully explains the syntax of addressing the cards.
Address the digital outputs cards one after each
other, starting with address 0 for the first digital
output card.
PS416-OUT-400
Two bytes are reserved in the central unit for the
16 outputs for each digital output card. The cards are
therefore addressed in two steps; only even-
numbered addresses are allowed.
A maximum of 18 PS416-OUT-400 digital output
cards can be used in each rack. In this case, the last
card is given the address 34.
Table 3-1 shows how poles 1 to 6 of the coding
switch must be set for each card address. It also
shows the output byte used to address the cards via
the software.
