Description

Byte StateUpstreamZoneInverce
0.0
0.7
0.0
0.15
Status of the upstream zone of the fieldbus controller in
ZPA mode with inverted direction of flow (current direc-
tion of flow ≠ configured direction of flow). Description of
the transfered data corresponds to 1 byte (StateUp-
streamZone)
Byte StateUpstreamZone
1.0
1.7
Status of the upstream zone of the fieldbus controller in
ZPA mode:
Value 0x01 Empty : There is no material to be con-
veyed in the zone and no material is arriving from the
upstream zone (sensor free, motor not enabled)
Value 0x02 Accepting: Zone is empty, but material to
be conveyed is arriving from the upstream zone (sensor
free, motor enabled)
Value 0x04 : Full and Running : There is material to be
conveyed in the zone and it is being conveyed in the dir-
ection of the downstream zone (sensor occupied, motor
enabled)
Value 0x05 Full and Stopped : There is material to be
conveyed in the zone and it is being accumulated there
(sensor occupied, motor not enabled)

1.15
Status of the downstream zone of the fieldbus controller
in ZPA mode with inverted direction of flow (current dir-
ection of flow ≠ configured direction of flow). Description
of the transfered data corresponds to 1 byte (StateUp-
streamZone)
Byte StateDownstreamZone
3.0
3.7
Status of the downstream zone of the fieldbus controller
in ZPA mode:
Value 0x01 Empty : There is no material to be con-
veyed in the zone and no material is arriving from the
upstream zone (sensor free, motor not enabled)
Value 0x02 Accepting: Zone is empty, but material to
be conveyed is arriving from the upstream zone (sensor
free, motor enabled)
Value 0x04 Full and Running : There is material to be
conveyed in the zone and it is being conveyed in the dir-
ection of the downstream zone (sensor occupied, motor
enabled)
Value 0x05 : Full and Stopped : There is material to be
conveyed in the zone and it is being accumulated there
(sensor occupied, motor not enabled)
