11.2.4 Meaning of the diagnostics values
11.2.4.1 Diagnostic value '1.STRKS - Number of total strokes'
Display range: 0 ... 4.29E9
Purpose: In operation, the movements of the actuator are summed up and
displayed in this diagnostics parameter as the number of strokes.
Unit: 100% strokes, i.e. the path between 0% and 100% and back.
11.2.4.2 Diagnostic value '2.CHDIR - Number of changes in direction'
Display range: 0 ... 4.29E9
Purpose: Every change in direction of the actuator is noted in the controller
and added to the number of changes in direction.
11.2.4.3 Diagnostic value '3.\\CNT - Number of fault messages'
Display range: 0 ... 4.29E9
Purpose: Every fault is noted in the closed-loop controller with '3. CNT' and
added to the number of fault messages.
11.2.4.4 Diagnostic value '4.A1CNT - Number of alarms 1' / '5.A2CNT - Number of alarms 2'
Requirement: '44.AFCT' Alarm function (Page 156) parameter is activated.
Display range: 0 ... 4.29E9
Purpose: This value indicates how often the alarm has been triggered.
