2.1.2.8 Adjustable 750-461/003-000 Variation
The operating mode of the 750-461/003-000 variation can be parameterized
using the WAGO-I/O-CHECK 2 start-up and diagnostic tool (Item No.: 759-
302).
The default setting is Pt 100. In this operating mode, the module has the same
behavior and process values as the 750-461 basic module.
The parameter dialog box of WAGO-I/O-CHECK 2 contains select boxes
that are used to set this module.
