12.2 Control bits (transmitted data bytes 0…3)

Byte Bit Name Description

0 Start 1 = Start feeding. Allow signal to remain until status bit "Feeding completed" = 0.

After each feeding process, the signal has to be set to zero before restarting is possible.

(continuous operation: scale feeds with signal = 1). 1 Clear bag

counter / total

1 = Bag counter is reset and the total weight deleted. (only possible in step 1 or 9. Only if bag counter mode CCLR = ON or with continuous operation).

2 Abort 1 = Switch to step 1.

3 FC alarm 1 1 = Fault in frequency converter of scale 1 (generates alarm FINV) 4 Refill release 1 = Refilling of all scales released.

5 Empty scale(s) 1 = Refilling and feeding time alarm is suppressed.

When all scales are empty, the status bit "Scale(s) empty" is set. 6 Acknowledge

"Tolerance alarm"

1 = Acknowledgement of tolerance alarms. Allow signal to remain until status bit "Tolerance alarm" = 0.

0

7 Acknowledge "New values ready"

1 = Delete status bit "New values ready" (leave until "New values ready" = 0).

0 Empty system 1 = Empty product feed and scales. Normal refilling continues until product feed is empty (suppression of filling time alarm). Then refilling and the feeding time alarm are suppressed. When all scales are empty, the status bit "Scale(s) empty" is set. 1 Cleaning 1 = Single filling of empty scale with cleaning quantity. Then

refilling and the feeding time alarm are suppressed. When all scales are empty, the status bit "Scale(s) empty" is set. 2 Continuous

operation

1 = Continuous operation 0 = Normal bagging mode.

(This setting can only be adjusted at the starting point, step 1.) 3 Release AO2 1) 1 = The recipe-specific actuating signal is generated at AO2. 4 FC alarm 2/3 2) 1 = Fault in frequency converter of scale 2 and 3 (generates alarm

FINV)

5 Bag 2)

hung on 2/3

1 = Bag is attached to the bag spout of the fast feed.

Release of fast feed for this cycle (signal must be active at start). 1

Profibus-DP Protocol Differential bagging scale (BAGD1, BAGD3) 63

Byte Bit Name Description

0 Refilling active 1 1 = Refilling of scale 1 is active, weight adoption / start is disabled. Must be set when refilling 1 is present and must be deleted with a delay.

(If the signal is not used [continuous 0], then weight adoption / start fix is delayed by 1.8s.)

1 Refilling active 2 2) According to byte 2/0 2 Refilling active 3 2) According to byte 2/0

3 Man. discharge 1 1 = Manual discharge of scale 1. The 24 V output "Dosing 1" is set as long as the signal is at 1.

4 Man. discharge 2 2)

1 = Manual discharge of scale 2. The 24 V output "Dosing 2" is set as long as the signal is at 1.

5 Man. discharge 3 2)

1 = Manual discharge of scale 3. The 24 V output "Dosing 3" is set as long as the signal is at 1.

Byte Bit Name Description

0 Operation 1 = Scale started (not in step 1 or 0). 1 No. of bags reached Only with bag preselection.

1 = Feeding of scale 1 is fully completed. 0 = During feeding of scale 1.

4 Release bagging 1 = Without bag preselection, if the preselected nominal value has not yet been reached.

0 = The preselected number of bags is reached.

5 Scale(s) empty 1 = All scales are empty. In the case of "Empty scale(s)", "Empty system" and "Cleaning operation", the signal switches to 0 at the start of the function and to 1 when the scales are fully empty.

6 Tolerance alarm 1 = The bag weight is outside the set tolerance limits REC.TOL+, REC.TOL–.

0

7 New values ready 1 = New values are available (new bag weight, counter). 0 = Control bit "Acknowledge new values ready" = 1.

0 Feeding 1 1 = Feeding of scale 1 (also release of frequency converter). 1 Refilling 1 1 = Filling of scale 1.

2 Filling time alarm 1 = Filling time alarm for scale 1, 2 or 3. The scale was unable to be refilled within the time TFIL. Reset with the control bits "Clear alarm" or "Empty scale(s)".

3 Weight of checked bag

1 = Current bag has been checked (check cycle) (always 1 for BAGD2/3).

4 Recipe output A 1 = when REC.RDOA = ON. 5 Recipe output B 1 = when REC.RDOB = ON. 6 Alarm 2 2) 1 = Alarm scale 2.

7 Operation 2 2) 1 = Scale 2 is currently in operation and can be used for feeding. 0 = Scale 3 is in emergency mode.

0 Feeding 2)
