Configuring “Racks” and “Slots”
Even though a VersaMax I/O Station does not have a module rack, both
autoconfiguration and software configuration use the traditional convention of
“racks” and “slots” to identify module locations. Each logical rack consists of the
NIU or an Expansion Receiver module plus up to 8 additional I/O and option
modules mounted on the same DIN rail. Each I/O or option module occupies a
“slot”. The module next to the NIU or Expansion Receiver module is in slot 1.
Booster power supplies do not count as occupying slots.
