Processor module
PM V12
Change: SAF filter: more firmly specified (old: 8/4/1,5; new:16/8;3) for teach-in.
04.04.2006
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.
PM V13
Change: Digital filter in mode „Flat specimen" extended by „bipolar".
19.03.2007
ATTENTION! The allocation of the digital output signals for „bipolar" and „Flat" deviates from the
standard.
Introduction: Signal-noise ratio
PM V14
Change: Signal-noise ratio extended to 40dB resp. >40dB
13.07.2007
PM V15
Introduction Profinet (errors)
20.10.2008
PM V18
Introduction Profinet (error-free)
01.05.2009
PM V19
Works well with new leakage flux module and with old module; for NETDCU 10 too
28.01.2010
PM V20
Same as V19 + Error magnetic field on start-up fixed
15.04.2011
PM V21
Error message „Fan defect" ,error fixe on old leakage flux module
08.09.2011
PM V22
New Profibus modules utilizable
24.04.2012
PM V23
Detection of speed measurement: Increasing to 2000 values for one tube turn. ( previously 500 values for
18.02.2014
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
Adaptation to NETDCU A5; also suited for NETDCU 10
01.01.2016
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.

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
