User to select an operand that will be used to select the target language. You can
use analog inputs or outputs from function blocks, marker bytes, marker words,
marker double words, analog outputs, or analog inputs as an operand.

out by the system. When MB1 is assigned a value of 1 in the program, the language
will be switched to English.
Language table
Column Description
Language
In the language table, you can assign any name of your choice to each lan-
guage in the project.
Download
Selecting <Yes> in the Download column will make the texts for the cor-
responding language be loaded onto the device. You can enter these texts for
each language in the text display editor under the tab for the selected dis-
play and entry element.
value
If the assigned operand assumes this value at runtime, the display will switch
to the corresponding language.
Default
You can select a language as the default language. Selecting <Yes> in the
Default column will make the corresponding language be selected whenever
the current value of the operand cannot be found in the Value column. In other
words, the default language will be used when a specific language is not
selected.
Time and number formats
The time and number formats for each language will be taken from the
formats specified in the corresponding column. Every text that is configured
will then need to be entered in each of the defined languages when defining
the text element in the text editor.

Signal diagram for text displays with different priorities
The following signal diagram shows four different text displays with different pri-
orities. The text display with the highest priority, D01, is displayed first. As soon as
D01_EN=0, other enabled text displays are output – D02 in this example. And as soon
as a text display with an alarm is enabled, e.g., D06_EN=1, the text display will be dis-
played and remain until the alarm is acknowledged with D06_AI=1. After the alarm is
acknowledged, the enable text display with the highest priority or with an alarm will
be displayed instead. In this example, D07 will be displayed until it is acknowledged
with D07_AI=1, after which the display will switch to D02, i.e., the only remaining text
display.
