Display elements for an output's FS enable
With the local enable principle (system environment A) or the enable principle (system en-
vironment B), FS outputs are activated via an ST section. An FS enable is assigned to each
of these FS outputs. The status of that enable is displayed via the enable LEDs (“FS0”,
“FS1”, “FS2” and “FS3”).
