UPT-6010
Version 2
8.7.6
External module / channel errors
The device diagnosis uses the diagnostic channel of the PROFINET protocol to display any UPT-6010 errors
directly on the PROFINET controller. There is a text message stored in the device master file (GSDML) for each
error which is automatically displayed in plain text on the PROFINET controller, provided the controller has this
capability.
The display of external module / channel errors can be activated or deactivated with the parameter at index 9. The
default setting for external module / channel errors is "on".
You can check the controller status by means of the user data regardless of this parameter.
8.7.7
Measuring impulse duration
The length of the measuring impulses generated by the controller can be set with the parameter at index 10. It
may be necessary to set a measuring impulse longer than the default 1.7 ms for certain applications.
8.7.8
Data format
This parameter specifies the order of the bytes ("Little Endian (Intel)” or "Big Endian (Motorola)") in the cyclic data;
this setting applies to both input and output data (
section 8.4 "Communication protocol" on page 23).
We recommend selecting "Big Endian (Motorola)" for Siemens PLCs.
8.7.9
Correction factor Co
The correction factor Co allows you to adapt the controller to the actual conditions in the machine (type of UPT
heating element, impulse transformer specification, length of connecting cables, cooling etc.). You can set the
required correction factor with this parameter.
Proceed as follows to determine the optimum correction factor Co:
1. Controller settings:
- Set temperature: 160…180 °C
- Sealing time:
0.20…0.30 s
2. Heating impulses (ST bit = 1):
Proceed as described in section 8.5.2 "Start (ST)" on page 25.
Slowly increase the correction factor, starting either with the lowest value (50%) or with the value recommended
in the ROPEX Application Report minus 25%, until the actual temperature at the end of the heating impulse cor-
responds to the set temperature.
The correction factor should be checked, and if necessary corrected, whenever the machine is operated or the set
temperature or the sealing time is changed.
