Adjustable 750-469/003-000 Variation
The operating mode of the 750-469/003-000 variation can be configured using the
WAGO-I/O-
CHECK
commissioning tool.
The default setting is Thermocouple Type K. In this operating mode, the I/O
module has the same behavior and process values as the 750-469 basic I/O
module.
The parameterization dialog in WAGO-I/O-CHECK provides the following
selection boxes for possible I/O module settings:
