11.2.4.14 Diagnostics value '15.DEVI - Dynamic control valve behavior'
Requirement: Monitoring of dynamic control valve behavior 'b.\\DEVI' (Page 168)
parameter is activated.
Display range: 0.0 ... 100.0
Purpose: This value in percent provides information about the current dynam‐
ically determined deviation from the model response.
11.2.4.15 Diagnostic value '16.ONLK - Pneumatic leakage'
Requirement: Monitoring/compensation of pneumatic leakage 'C.\\LEAK'
(Page 170) parameter is activated.
Display range: 0 ... 100
Purpose: This diagnostics parameter shows the current leakage indicator.
11.2.4.16 Diagnostic value '17.STIC - Stiction (slipstick)'
Requirement: Monitoring of stiction (slipstick) 'd.\\STIC' (Page 173) parameter is
activated.
Display range: 0.0 ... 100.0
Purpose: This diagnostics parameter shows the filtered value of the slip
jumps in percent resulting from the stiction.
11.2.4.17 Diagnostic value '18.ZERO - Lower endstop'
Requirement: Monitoring of lower endstop 'F.\\ZERO' (Page 176) parameter is
activated.
'39.YCLS' Tight closing/fast closing with manipulated variable
(Page 153) Parameter is set to one of the following values: 'do', 'uP
do', 'Fd', 'Fu Fd', 'uP Fd', 'Fu do'
Display range: 0.0 ... 100.0
Purpose: Indication of how many percent the lower endstop has changed
compared to its value during initialization.
