Introduction
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.
• 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.
Requirements:
• 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.
