12.3.2
Read window (output area)
Data are transferred from the slave (PR 5410) to the master in this window.
The data required for monitoring and controlling filling does not fit in a 64-byte write
window. For this reason the system differentiates between system and material
parameters. The value of the first byte can be used to determine whether the data refers
to the system or the material.
12.3.3
Indicator functions
E. g., gross, net, tare; all indicator statuses and commands are available at the same time.
In contrast to the 8-byte interface, in the 64-byte interface the parameters, statuses, and
values are all available simultaneously.
Some values may be output as data type DINT or REAL depending on write bit 2 in byte 2.
12.3.4
Filling functions
12.3.4.1
Filling start
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 5410).
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 5410).
1.
Write the material parameters.
2.
Set start bit:
1.
Write the material ID to byte 3.
2.
