Parameter concept of the measuring cycles

2.1
General
Measuring cycles are general subroutines designed to solve specific measurement tasks,
which are suitably adapted to the problem at hand with parameter settings. They can be
adapted for this purpose via defining parameters.
The measuring cycles also return data such as measuring results. They are stored in result
parameters.
These measuring cycle parameters are called Global User Data (abbreviated to GUD).
They are located in the battery-backed memory of the control. These values are therefore
not lost when the control is switched off and on.
Data block
The global user data is kept in data blocks.
• GUD5.DEF
• GUD6.DEF and
• GUD7.DEF (for measuring in JOG)
Delivery of the measuring cycles
On delivery, these data have default settings (see Section Parameter overview). These must
be adapted by the user or machine manufacturer on installation (see chapter Data
description)
Value assignments
The defining parameters must be assigned values before the measuring cycle is called:
• Either in the program or
• Operator input in the measuring cycle support
Data display
The data in the operating area "Parameters" can be displayed by means of "User data",
"Global user data", "GUD..." or "Channel-specific user data", "GUD...".. As an alternative,
parameters that are not assigned values in the program or in the measuring cycles support
can be assigned values directly by experts.
