14.3 Digital Outputs
The
Operation mode Digital output 1
530 and the relay output with the parameter
Operation mode Digital output 3
532 link the digital outputs to various functions.
The selection of the functions depends on the parameterized configuration. The use
of the multifunctional output MFO1 as a digital output demands selection of an
Oper-
ation mode
550 and linking via parameter
