Change: SAF filter: more firmly specified (old: 8/4/1,5; new:16/8;3) for teach-in.
This filter is preferably used since being introduced. With the old settings the filter showed results “good”
to “very good” even with weak seam signals. Thus tubes with unsuitable seam signal were falsely declared
practicable. The new settings prevent from such mis-interpretations.
Introduction: Bus interface Profibus
Introduction: PLC interface additional input „Reset Fault “
Was introduced in order to permit the PLC to reset a fault condition.

Change: Digital filter in mode „Flat specimen“ extended by „bipolar“.
ATTENTION! The allocation of the digital output signals for „bipolar“ and „Flat“ deviates from the
standard.
Introduction: Signal-noise ratio
PM V14
13.07.2007
Change: Signal-noise ratio extended to 40dB resp. >40dB

Introduction Profinet (errors)
PM V18
01.05.2009
Introduction Profinet (error-free)
PM V19
28.01.2010
Works well with new leakage flux module and with old module; for NETDCU 10 too
PM V20
15.04.2011
Same as V19 + Error magnetic field on start-up fixed
PM V21
08.09.2011
Error message „Fan defect“ ,error fixe on old leakage flux module
PM V22
24.04.2012
New Profibus modules utilizable
PM V23
18.02.2014
Detection of speed measurement: Increasing to 2000 values for one tube turn. ( previously 500 values for
one tube turn)
Slippage: Minimum adjustability 0,1 % (previously 1% )
Sample rate: maximal 120 (previously 30)
Internal signal type calculation: 8 kHz (previously 2 kHz)
PM V24
01.01.2016
Adaptation to NETDCU A5; also suited for NETDCU 10
Delivery only with leak flux module 750mA
In combination units and leak flux units following the serial number 400052 (mid-April 2006) the
leak flux module 750 mA will be used.
Exception: Units with / for coil seam sensors NS9…EC.
Note for units with cable driver
Attention!
For units with cable driver module, please consider the following:
- Reduce the output voltage when using the cable driver:
- 0…25KHz = 20 Vss (no reduction)
- 50…100 KHz = 17 Vss
- 400…800 KHz = 5 Vss
