However, only one functional mode is permitted at a time. The internal relays
automatically assume the functional mode of the module connected. Interest-
ing possibilities with relay modules are :
- variant 2 :
assigning the relays to particular limit values and
- variant 8 :
allowing the relays to be driven from the computer. The following table pro-
vides an overview of the programming options for the external modules :

programmed to variant 2.
Alarm cable variant 2 ´Relays assigned internally´ also requires the assignment
of relays to particular limit values (see Section 9.10.3) by activating maximum /
minimum action in the special functions.
Variant 8 ´Relays driven externally´ makes it possible to manually control the
relays via the keyboard or via the user interface; (see Manual, Sec. 6.10.10).
