Configuration modes
5.4.1
General, Online and Offline modes
The settings in the configuration modes onPA and AdAP and the selection in the selection
mode (see fig. 5-2, page 153 takes place in online mode, i.e. the controller continues operating
in its last mode. The onPA and AdAP modes are entered directly from the selection modes by
pressing the Enter key (11). The analog x display (1) and w display (2) still display the process
image so that the reaction of the controlled system to parameter changes can be read off di-
rectly. The Internal LED (17) and Manual LED (12) and the Alarm LEDs A1 to A4 indicate the
current operating state. The Internal/External key (16) becomes the Exit key, the corresponding
CLED (18) indicates ready to exit, i.e. every time the LED flashes, pressing the Exit key jumps
from the selected mode to the next level up in the hierarchy.
The Automatic /Manual key (11) becomes the Enter key, the corresponding y external LED (13)
indicates ready to enter, i.e. whenever the LED flashes, pressing the Enter key jumps to the
next level down in the hierarchy.
Press the Enter key (11) for 3 s to go from the preselection mode to the offline mode with the
oFPA, StrS, APSt and CAE3 menus The user stays offline when returning (from offline menu)
to the preselection mode. When subsequently jumping to another off line mode the three-sec-
ond time condition is irrelevant. The three-second time condition for entering an offline menu is
only valid again after exiting the offline mode by selecting an online mode with the onPA and
Adap menus or exiting the preselection mode. The controller switches into the
absolute
manual mode
(offline mode), i.e. the last manipulated variable of the online mode is retained
(in K-controllers the last manipulated variable, in S-controllers no positioning increments are
output). A change in the manipulated variable using the
±
Δ
y-keys (7), (8) is not possible, the
control signals N (DDC), Si and
±
yBL are not effective. The analog output, the digital outputs
and the alarm LEDs A1 to A4 are held at the last value or status. To identify the offline mode,
the analog w display shows a striped pattern and the manual LED (12) lights up. The absolute
manual mode is retained when returning to the parameterization preselection mode (online
mode) or the process operation mode from the structuring preselection mode with the Exit key
(16). This also applies if only automatic operation has been preselected with S51 = 1. The con-
troller must also be reactivated in the process operation mode for safety reasons by switching
to automatic operation.
The analog x display (1) continues to display the controlled variable x during offline mode, the
Internal LED (17) the current status. The control elements keys (11), (16) and the LEDs (12),
(13), (17), (18) have the same function as in the online configuration modes.
If the control signal bLPS = 1, parameterization and structuring is blocked, no PS (w/x and y
displays) appears when you press the Shift key.
If the control signal bLS = 1, structuring is blocked. Only onPA and AdAP appear in the selec-
tion mode.
.
NOTE
Please note that changed parameters and structure switch settings are only
transferred to the failsafe EEPROM after returning to the process operation
mode.
