7.6.61.2 Compare actual position with values stored
l PSAVE-ON = HIGH:
– The inputs PSAVE-MPOS and PSAVE-ACTPOS are compared with the stored values. The
deviations are output at PSAVE-M-DIFF or PSAVE-ACT-DIFF.
PSAVE-M-DIFF  gespeicherterWert 
{
PSAVE-MPOS
}
PSAVE-ACT-DIFF
 gespeicherterWert 
{
PSAVE-ACTPOS
}
– The evaluation of one of the channels can be suppressed by means of a code. In this case,
PSAVE-DIFF = 0
l PSAVE-ON = LOW:
– The outputs remain PSAVE-DIFF = 0.
7.6.61.3 Output of status signals
The digital outputs are set according to the difference calculated (PSAVE-DIFF), is PSAVE-ON =
HIGH.
l The hysteresis can be set via code:
– for MPOS C1430/1 in m-units
– for ACTPOS C1430/2 in s-units
l as long as -DIFF < C1430/x:
–-M-HI=LOW
–-M-LO=LOW
–ACT-HI=LOW
–ACT-LO=LOW
l if -DIFF pos. and > +C1430/x
–-M-LO=HIGHor
– ACT-LO = HIGH
l if -DIFF neg. and < -C1430/x
–-M-HI=HIGHbzw.
– ACT-HI = HIGH
l If one channel is suppressed through code C1431, the outputs of the corresponding channel
are set to LOW.
