10.3 Calculation of the input delay t
d
for muting in
conjunction with a M4000
The following information only applies to applications where an M4000 Advanced is
operated on the SDL connection of the UE4155
and the muting sensors are connected via
PROFIsafe.
When using muting in conjunction with an M4000 a minimum distance
L between the
recognized object and the M4000 must be calculated. To calculate the minimum distance
L the input delay t
d
of UE4155 is required.
How to calculate the input delay t
d
:
Please also observe the information on the arrangement of muting sensors in the
operating instructions of the M4000 multiple light beam safety device in the chapter
“Arrangement of muting sensors“.
You can route the signals of the muting sensors to M4000 in two ways:
Connection of the muting sensors via the FPLC (see Tab. 22)
Connection of the muting sensors to UE4155 bus node PROFIsafe, cross routing (see
Tab. 23). This requires function package UE4100 for M4000.
Line Required detail Time
1 The muting sensor switches via the FPLC. The information
of the muting sensors is available at the bus nodes.
The following times must be totalled among others:
response time and processing time of the muting
sensor
processing time of the input card
bus communication of the input card
FPLC
processing time of the FPLC
FPLC bus communication
of the bus node
(Worst case conditions apply to all these parameters.) + ______ ms
2 Internal processing time of the bus node + 6 ms
3 Total = input delay t
d
= ______ ms
Line Required detail Time
1 Longest set input delay of all field signal inputs to which a
muting sensor is connected
+ ______ ms
2 Internal processing time of the bus node + 6 ms
3 Total = input delay t
d
= ______ ms
