Download Absolute Rotary Encoder with Profibus

4.1.8 Upper limit switch
A total of two positions can be programmed. When
these positions are fallen below or exceeded, the
absolute value encoder sets bit 27 to one in the 32
bit process actual value; within the range it is zero.
Both limit switch values may not exceed the value
set for parameter ‘Total measuring range’. The
Upper limit switch is activated using bit 6 in octet
26 and the position value for the upper limit switch
is saved in octets 31 to 34:
