Entry and display of texts

Changing the texts displayed in the unit is only possible in the engineering tool! Max. 16 characters can be entered
into each text parameter. Dependent on whether a line was configured as an analog, digital, radio, switch, push-button
or menu line, all 16 characters (e.g. mMode x =

digital) or only the first 6 characters (e.g. mode x= analog)

are shown in the device. Further detailed information on the various display types is given at the end of the section.

With digital displays (digital, switch, push-button and radio):

signal = 0: dependent of line of ‘Text1 a ... Text6 a’
signal = 1: dependent of line of ‘Text1 b ... Text6 b’

VWERT operating page

The VWERT operating page can be selected in the operating page menu with non-activated ‘

hide

‘ input.

For information on the operation, see section Operating pages
on page 36

If aline is configuratd as display, the value can't be changed.

Operation of line modes radio, switch and push-button is des-
cribed in section

I.9.4 "Adjusting values".

When using the VWERT block in an enginering, operation and
function must be described separately.

VWERT block cascade connection
For linking several VWERT operating pages, the Bl-no output of a further VWERT must be wired with the Casc input of
the calling VWERT. Thereby, the last page which must be connected can be linked also to the start page (ring structu -
re).

Cascade connection of a VWERT block is indicated by arrows

pq on the display page. A previous block (Bl-no output

wiring) above the first line and a next block (Casc input wiring) below the last line are marked, otherwise, these arrows
are omitted. When setting the cursor onto one of these arrows and pressing key Enter, a change to the relevant
VWERT page occurs. With standard exit from the called up VWERT page a change to the selection list of the operating
pages is made.

Selectable display modes in detail

Data type “analog”
The line contains 2 static texts (6 characters) and the analog va-
lue connected to X1...X6. Changing the value is done as descri-
bed above, if changeability is configured.

With the corresponding input Xn wired via a type ALLP function
block, its limits H1 (max. limit) and L1 (min. limit) are used as ad-
justment limits for this value. Unless an ALLP block is connected
to the input, limits –29999 to 999999 remain valid.

Example: Value with limits:
Apart from its maximum number of digits behind the decimal
point, each value can have its own adjustment limits, which are
determined by parameter values L1 and H1 of a previous ALLP
block. Unless the source of the display value is the VWERT, the
ALLP uses these parameter values for limiting the value.
