6.7.4 Step level result variables
The Step level data is the data that can be reported for each individual step in a tightening cycle. It is
divided in two parts, Common data and Check data, where the first covers all variables that available for
all steps and the latter all variables produced by checks executed for the step.
Common data
This section lists all variables that are available for all steps without any specific configuration.
Variable name Description
Step No The step number. This is the order of the step within the program. First step is one (1).
Steps within a sequence are given the step number P * 100 + S where P is the step number
of the SE step that calls the sequence and S is the step number within the sequence.
Step Type The numerical representation of the type of step. See the definition of the respective step
for valid values (Step
– Control).
Par The parameters of the steps control part. See the definition of the respective step type
(Step
– Control) for which parameters that are printed, and in which order.
Note This variable always prints 10 values. If fewer parameters are used for a step then the
unused will have the value NOT_DEFINED.
Speed The target Speed for the step.
A Chan Con The angle channel used for step control
T Chan Con The torque channel used for step control
Errors Step errors that have occurred, see Errors.
Step Name Step name
Check data
The check data consists of the variables that are produced as a result of running a check, a restriction or
produced by the steps control function.
In addition to the variables listed below the high and how limit set up for it, as well as the Cp, Cpk, and
Cam SPC values calculated for them, are also available as result variables.
Each check data variable is defined once for each possible choice for check channel. The first variable is
reported when the default check channel is used (Monitoring).
Variable name Description
Peak T
Peak T1
Peak T2
Peak T3 The highest torque reached during the step. Produced by the "Check peak torque"
check.
