12.3.4.1.1 General information
There are two ways to carry out filling:
-
(A) Filling parameters are written at each start by the PLC.
-
(B) Filling parameters are stored in the device (PR 5220).
Requirements:
The system is ready.
The device has been checked to ensure it is ready for the start of filling. It is ready when
no filling is currently taking place and no parameters are being changed.
This status is signaled by bit 2 (Ready) in byte 3.
12.3.4.1.2 Filling start A
The material parameters can be found in the PLC.
-
Set point
-
Preset
-
Material overshoot (OVS)
-
Tolerance above/below set point
-
Calming time
Byte 1
These parameters are applied with the rising edge of the start bit. If the parameters
are valid, the filling process is started and the Dosing_Run bit is set.
The end of the filling process is signaled by the falling edge of the Dosing_Run bit.
12.3.4.1.3 Filling start B
The material parameters can be found in the device material table (PR 5220).
0000 1000 in byte 1

Filling control
12.3.4.2.1 Pausing filling
Requirements:
The system is filling, i.e.,
-
the Dosing_Run bit is active
and
-
the hold bit is not active
Example:
Set stop bit with 0100 0000 in byte 1.
Filling stops with the rising edge and the system goes to the hold status (hold state).
If the system is in hold state, filling can be restarted or canceled.
