If the text displays are retentive, the actual value is retained when the
operating mode changes from RUN to STOP as well as when the power
supply is switched off.
When easy is restarted in RUN mode, the text displays D1 to D8 continue
with the retentively stored actual value.
Example of a text display:
The text display has the following display characteristics:
4.7.3 Scaling
The values of the analog inputs can be scaled.
4.7.4 Function
The D (D = “Display”) text display function relay works in the circuit diagram
like a normal M marker. A “1” signal at the coil will cause a stored text to be
displayed in the easy display line. For this to take place, the easy must be in
RUN mode and the Status display must be activated before the text is
displayed.
The following rule applies to D2 to D16:
• If several texts are present and are triggered, each text is displayed
automatically in turn every 4 s. This process will be repeated until:
• No other text display function block is set to 1.
• STOP operating mode is selected.
• easy's power supply is no longer present.
• A menu was selected via OK or DEL + ALT .
• A setpoint value is entered.
• The text for D1 is displayed.
The following function applies to D1:
• D1 is designed for alarm text. If a text has been assigned to D1 and it is
activated, this text is shown permanently in the display until:
• The coil D1 is reset to 0.
