15.3 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 func
tions.
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 Digital operation MFO1 554.
