Mode Selector, Rotary Table
In "Mode Selector" mode, you can connect 2, 3 or 4 inputs to
a mode selector and to test pulse output SI0 TP. Disable the
test pulse outputs you do not need. Use this setup together
with PLC component FB_MODE to implement a mode
selector switch. The associated logical output sets only if an
input is set. All other outputs remain in a safe state. If no or
more than one input is set, all logical outputs retain their safe
state.
Use FSoE parameter "External Input" to enable the "Mode Selector" function. Refer to manual
section
