Bit Feedback signal Remarks
4 Spare Reserved for
future use
5 in LE; VVS in Leading End Centering Only one of
these
signals is
active at a
time.
6 in BD; VVS in Body Centering
7 in TE; VVS in Trailing End Centering
8 Send Parameters Done
This bit is set by VVS after the parameters have been read as
initiated by the send parameters command bit (8).
-
9 Rear roll down
This bit is set when material is detected. The rear (1st) clamp roll can
now be lowered by the PLC.
The bit is reset when no material is detected.
-
10 Front roll down
This bit is set when a length of material set in the system parameter
"Clamp Position" is detected. The front (2nd) clamp roll can now be
lowered by the PLC.
The bit is reset when no material is detected.
-
11 Faulted
This bit is set when one of the major sensor errors or a motor error is
reported.
The status words 1 and 2 are compared with the bit masks 30FF and
003F. This means the bits 0 -7, 12 and 13 in the sensor error word 1
and the 6 motor error bits of word 2 will cause a major fault signal.
-
12 Material under sensor
For breaker
True if the camera detects 2 edges, else false
For Carcass:
True if both cameras detect an edge, else false.
For 90° breaker and Tread:
True if measured width larger than obstruction width, else false
-
13 Busy
Busy Homing or busy centering.
If the busy signal doesn't become high when a command is given,
the VVS software is not running. PLC software will timeout after 5
seconds and restart the given command.
Time-out on
this signal
14 Holded
High when hold command is active.
Use this bit to start the transport of the conveyor belt after a hold
command.
-
15 Heartbeat
This signal changes state every second. PLC should timeout after 2
seconds. If heartbeat restarts after a timeout, product parameters
should be send to the VVS system.
Time-out on
this signal
2 seconds.
