6. Function blocks
6.1 Manufacturer function blocks
Display priority
If multiple text displays from D01 through D32 are enabled simultaneously, the display
priority will be used to determine the order in which they will be displayed on the
easyE4 device display. The text display with display priority 001 will have the highest
priority, while the text display with 032 will have the lowest priority. The text display
with the highest priority will be displayed as long as it is enabled (EN=1). The text dis-
play with the next highest priority will not be displayed until the function block input of
the previous text display is disabled (EN=0). If multiple text function blocks with the
same priority are enabled, the corresponding texts will be displayed in a rolling pattern
based on the rolling time. Moreover, when a text display with an alarm becomes
enabled, it will be displayed on the device display immediately. (Please refer to the
Alarm parameter as well.)
Rolling time [s]
The rolling time parameter is used to specify how long text displays that have the exact
same display priority will be displayed on the device display. In order for this parameter
to do something, multiple text displays must be enabled simultaneously (EN=1). Please
note that the rolling time is specified in seconds. Moreover, when a text display with an
alarm becomes enabled, it will be displayed on the device display immediately. (Please
refer to the Alarm parameter as well.)
Alarm
If this checkbox is enabled, the corresponding text display will be displayed with abso-
lute priority until the device operator acknowledges the alarm via a rising edge at input
AI. This function is only effective for visible function blocks
If multiple text displays with an alarm are enabled simultaneously, the first one that
was enabled will remain on the device display until it is acknowledged by a rising edge
at input AI. The next text display will be shown then. Once all the text displays with an
alarm have been acknowledged by a rising edge at input AI, the text display with the
highest priority will be displayed on the device display.
It is important to keep in mind that the alarm acknowledgement function at function
block input AI always expects a rising edge. In other words, the AI function block input
does not need to be acknowledged immediately, but it does, however, need to be
acknowledged by the next alarm reset at the latest.
Activation P buttons
The P buttons on the easyE4 device can be used for input and menu control purposes at
runtime. You can use these parameters to individually define which buttons should be
enabled, and the specific button configuration can be different for each individual text
display. Please note that the buttons are required only if you need the operator to enter
input or switch screens.
