Since, depending on the configuration, the block itself forms the digital feedback signals
internally via the "Open" and "Closed" positions, the following reaction results from the
"Feedback open" and "Feedback closed" signals.
● Control valve:
– "Feedback open": The display is derived from the FbkOpenOut output. However, this
output is formed from the configured limit for the "Open" position.
– "Feedback close": The display is derived from the FbkCloseOut output. However, this
output is formed from the configured limit for the "Closed" position.
● "Control auxiliary valve": only visible when there is a auxiliary valve
– Control binary control Ctrl.Out
– "Feedback Open auxiliary valve": FbkAuxVOpenOut.
– "Feedback Closed auxiliary valve": FbkAuxCloseOut.
– “Control channel auxiliary valve": Signal for control of the auxiliary valve from the output
channel block
