13.2 Control and Feedback Interface (PIQ/PII)
You can configure the address space of the control and feedback interfaces of the
4 IQ-SENSE. You can choose between Standard and Enhanced.
Standard Features
 The 4 IQ-SENSE occupies 4 bits in the feedback interface.
 The 4 IQ-SENSE can be grouped in a single byte. Two 4 IQ-SENSE modules
can be grouped in each byte. See also Section 6.1.
 You can evaluate the circuit state of each channel using the feedback interface.
Enhanced Features
 The 4 IQ-SENSE occupies one byte in the control interface and one in the
feedback interface.
 You can use the control interface to specify the sensitivity and distance values
for each channel (IntelliTeach via “IQ-SENSE Opto” FB) and execute teach-in.
 You can use the feedback interface to evaluate the acquired sensitivity and
distance values (switching threshold) and the circuit state for each channel.
Prerequisites:
 You can use the “IQ-SENSE Opto” function block. The FB facilitates easy
access to the control and feedback interface.
 Please note that in this case PII equals PIQ.
 You can download the function block and the relevant product information on
the Internet at http://www.ad.siemens.de/csi_e/gsd.
