Standard wiring of interface
Measuring procedure by external PLC
Note!
For the external triggering of a measuring with IN0, a valid program must be selected (externally or via keyboard) and the
unit must be in
”Automatic - Ready
” condition.
Parallel Data Inputs
1)
IN0
/ Measuring Start
IN1
/ Program selection
Parallel Data Outputs
1)
OUT0
/ Meas. Start active
OUT2
/ Ready for measuring
OUT3
/ Setup active
OUT4
/ Slippage
OUT5
/ General fault
OUT6
/ Reduced detecting capability
OUT7
/ Motor
IN0 and IN1 are edge triggered interrupt inputs. In the standard configuration the positive flank is active. Both inputs must
not be activated simultaneously. The min. time between 2 commands must be >20 ms. IN1 is the strobe input for the data
inputs IN2 to IN6.
The output signals OUT2 to OUT6 have two different functions.
On externally activating the command
”Program selection IN1
“ the input data IN2 to IN6 are mirrored at the outputs OUT2 to
OUT6, in order to enable transmission monitoring.
On externally activating the command
”Measuring Start IN0
“ the measuring result and status messages will be reported. In
the standard configuration High Level = active.
t1: < 20 ms
t2: < 30 ms
t3: Depending on tube diameter and turn rate.
t4:
≥
0 ms
t5: > 30 ms
