As these figures illustrate, the term "station" combines both the
communication adapter module and its connected programmable
controller processor. (When specifying only the individual processor or
communication adapter module at a station, the terms "station processor"
or "station communication adapter module" are used.)
The following sections describe the functions and compatibility of each
station hardware component.
A communication adapter module (cat. no. 1772-KA2) provides the
