Setting the PROFIsafe clock cycle
•
MD 10071 $MN_ IPO_CYCLE_TIME = 0.006 s
•
MD 10098 $MN_PROFISAFE_IPO_TIME_RATIO =

In the case of an agreement button connected-up in an exclusive OR
configuration, when OK, the signal state is transferred to the SPL defined by
the lower channel (channel 2 in the example).
$A_OUTSE(P) variables 1..4 are output to the F-DO module
•
MD 10387 $MN_PROFISAFE_OUT_ADDRESS[0] =
05 00 03 FD
H
•
MD 10389 $MN_PROFISAFE_OUT_ASSIGN[0
=
004 001
$A_OUTSE(P) variables 5..7 are output to the PM-E F module
•
MD 10387 $MN_PROFISAFE_OUT_ADDRESS[1] =
05 00 03 FC
H
•
MD 10389 $MN_PROFISAFE_OUT_ASSIGN[0]
=

A few definitions are now required in order to explain a safe programmable
logic (SPL). This is the reason that not all of the parameterized machine data
for Safety Integrated will be described. Furthermore, axial machine data are
only specified to represent an axis.
