Programming the Operating Panel
The message texts and system parameters are
programmed on standard programming units
under MS-DOS. The "EBELT" software
required for this process and the corresponding
connecting cables are included in the
installation set. The configuration shown below
can be used to program the operating panel
and to program the PLC for all PLC
connections with an integrated "PG-MUX".
The text memory is divided into 3 areas:
- loadable character generator
- system settings
- message texts with variable definition
Depending on the device type, a Flash-Eprom, EEPROM or a Memory Card is used as text memory.
Depending on the device, the memory capacity is between 8 Kbytes (EEPROM) and 512 Kbytes
(Flash-EPROM).
1. Loadable Character Generator
In addition to the internal character generator,
the BEST operating panels with LED text
display allow loading of a second character set
which is independent of this character
generator. This allows for mixed representation
of various character sets on the display. As the
character generator consumes a certain
amount of space in the text memory, it always
comes with a text memory of at least 32
Kbytes. It can, however, be enabled in the 8
Kbytes version, on special request.
Operating panels with LCD text displays
provide only 8 freely definable characters with
one used by the firmware to represent an
acceptable "g". This leaves 7 characters which
can be used freely by the user (reference
characters are the numbers 1...7). The freely
definable character generator is created with
the programming software under MS-DOS.

Page: 4Programming the Operating Panel Editon 2/94
2. Programming the System Settings
All operating panel system parameters are set
in plain text. This offers the advantage of the
parameter settings being documented in an
understandable language together with the
message texts. The system settings appear in
front of the message 0.
The presettings do not have to be typed in letter
by letter! Connect the operating panel to your
programming unit and select the menu item
Read text display“ in the EBELT software.
The default setting (or the currently
programmed setting) is supplied, allowing you
to simply make modifications as desired.
The following parameters can be set:
Message text selection binary/BCD
Internal character set CPM/IBM
Display brightness (for LED displays)
Scroll and blink times
Communication flag for keys and LEDs
Keyboard characteristics (push-button keys or
latch-down keys)
LED characteristics (internal/external/color)
Printer connection on/o
2.1 Valid System Settings
Example: BEST224-12-Z
* Binär (1)
The binary system is used for message text
selection (in contrast to the BCD system). The
possible number of message texts is 1000 + 23
system messages.
* BCD (1)
The BCD (binary coded decimal number)
system is used for message text selection. The
number of message texts is therefore limited to
400.
* Cpm (2)
The first internal character set is loaded in
accordance with the ASCII-table used with
CPM.
* IBM (2)
The first internal character set is loaded in
accordance with the character table used with
the IBM PC.
* Scrollzeit: 3,2 (4)
When a message with more than 2 lines is
programmed and to be displayed on a 2-line
display, the display will automatically begin to
scroll the text one line at a time. This scroll time
can be set to a time between 0,1 and 6,3 s.
* BLink-Ein: 0,2 (5)
The Blink-On duration can be set to a time
between 0,1 to 6,3 s.
* BLink-Aus: 0,2 (6)
The Blink-Off duration can be set to a time
between 0,1 to 6,3 s.
* Ko-M Tast: 10 LED: 02 (7)
Communication flag for F-keys and LEDs
Exception: S5 is parameterized in the data
handling block.
* Ta-Mode/LED/Farbe/Blink (8)...(11)
The following lines vary with the different
operating panels depending on the number of
function keys and the assigned LEDs. For
operating panels with only 12 function keys,
they are defined in one line. For operating
panels with more function keys, a new line is
used for every 8 function keys.
* Ta-Mode: MBBBMMMM MBMB (8)
The key mode can be defined separately for
every key. M stands for monostable or push-
down key, B stands for bistable or latch-down
key. The sequence is read from left to right.
* Ta-LED: EIIIIEEE IEIE (9)
LEDs in the keys can be activated either
internally (directly by the key) or externally by
the PLC. E stands for externally, I stands for
internally. The sequence is read from left to
right.
*Binär (1)
*Drucker (12)
*IBM Zeichensatz (2)
*Helligkeit: 80% (3)
*Scrollzeit: 3,2s (4)
*Blink-Ein: 0,3s (5)

BEST 224 ready for operation

BEST240-24-Z Editon 2/94 Page: 5
* Ta-Farbe: RGRRRGGG RGRG (10)
The color of the LEDs above the F-keys can be
selected: R or 1 stands for red, G or 0 stands
for green.
* Ta-Blink: EAAAAAEA EAEA (11)
A blink mask can be defined for the illuminated
keys: E or 1 stands for Blink-On, A or 0 stands
for Blink-OFF.
The blink bits from the PLC and the blink
setting
in the operating panel are linked in accordance
with the logic operation "OR".
* Drucker (12)
Most of the BEST-variants allow connection of
a logging printer. In this case, the printer
(instead of the PC) is connected to COM1 of
the operating panel. However, the printer can
not be connected while the internal PG-MUX is
to be operated.
3. Message Structure
In addition to the text to be displayed, the
following information is programmed in the
message texts:
-variable format
-variable address for variable to be displayed
or to be edited
-input limits for input variable
-numbers of function keys that are to be reset
on actuating the Enter-key
-info text
The structure of a message can be visualized
as consisting of four sections:
Example:
Section 1 Variable definition
2Section 2 Display message image
Section 3 F-key reset
Section 4 info text
Section 1 is used to define the variables. That
is, the format, address and input limits of the
variables are defined here.
Section 2 shows the actual message image
with the filler characters (_) holding the place
for the variables. The number of filler
characters determines how many digits are
displayed. The input cursor is displayed as a
blinking cursor. The variable does not have to
be programmed as a blinking variable.
Section 3 is the separation line to the info text
and also contains a list of up to 8 F-keys which
are reset by pressing the Enter-key, if they are
set. The list applies while the message text is
being displayed.
Section 4 contains the info text which can be
called up by the operator with the info key. The
LED above the info key is lit if an info text is
available.

Page: 6Programming the Operating Panel Editon 2/94
3.1 Variable Definition
Up to 8 variables can be displayed or edited in
a message. In this case, variables are numbers
(16 bit or 32 bit). The data format is specified in
the definition line.
When a message is called up, the variables are
automatically read from the PLC and replace
the filler characters holding the place for the
variables.
Every variable is assigned to one block of filler
characters. This block determines the number
of variable digits (displayed).
Example:
The variables are defined line by line
and displayed in the message text in that order.
In the message text, every group of connected (_)
underlines represents filler characters holding the
place for a variable.
2
3.2 Message Texts with Filler Characters for Variables
Blocks of filler characters are separated by any
characters except "." and ",".
If the maximum number of 8 variables is used
per message text, they can no longer be
displayed on a two-line display at once. To
allow input, the message image is not
automatically scrolled (scroll time), if input
variables are programmed in a message. The
lines are displayed in such a way that the input
cursor is visible. An input variable must
therefore be inserted in at least every second
line.
If scaled variables are used, one line is required
to specify the scaling range. This reduces the
maximum number of variables by one each.
Specifying an index register for variables or
input limits also reduces the possible number of
variables by one.
3.3 Function Key Reset
The line with the character "@" separates the
message text from the assigned info text. Up to
8 function key numbers can be specified in this
line. The individual numbers are separated by a
space, stop point or comma. If the specified
function keys are programmed as bistable
(latch-down) keys and are currently set, they
are reset by pressing the Enter-key if the input
has been carried out correctly (range check).
3.4 Info Texts
In addition to every message and menu text, an
info text can be programmed. The red LED
above the (i) info key signals that an info text is
available for the message currently displayed.
Pressing the info key displays the programmed
info text in place of the message text. When the
info key is released, the message text is
@uns 16!
@bcd 18 1500 8000
@bcd 20 100 2700
Process inspection ACTUAL: ___
SETPOINT: ___ DIM.: __,__ mm

BEST240-24-Z Editon 2/94 Page: 7
displayed again. The info text display does not
interrupt an ongoing input process. This means
that after the info key is released, the input
cursor is in the previous position. It is not
possible to display variables in the info text.
Except for the identifier "@", only the numbers
of function keys to be reset are allowed in the
separation line.

Page: 8Programming the Operating Panel Editon 2/94
4. Variables
The variable definition is placed in front of the
message text as already described. In order to
distinguish the variable definition from text lines,
the character "@" is inserted in front of the
variable definition.
General Syntax:
@[tttt]o[xxx]o[!]o[min]o[max]
@[tttt] =variable format
[xxx] =variable address
[!] =identifier for an indication
variable
[min] =lower input limit
[max] =upper input limit
In this case, the box (o) stands for a space.
When creating text, the underline represents a
filler character holding the place for a variable.
4.1 Indication Variables
The character "!" signifies an indication
variable. Indication variables are continuously
read from the PLC. Input is not possible (e.g.
temperature display).
Example:
4.1.1 Suppression of Leading Zeros for Indication Variables
Indication variables allow suppression of
leading zeros for the following variable formats:
UNS, BCD, BCDL
The character "!" is replaced by a "#".
Example:
4.2 Input Variables
If limit values are specified after the variable
address, this variable is first read once from the
PLC and is then be released for an input
process. When the Enter-key is pressed, the
entered value is checked to ensure that it is
within the specified limits. If the value has been
entered correctly, it will be written (back) to the
PLC at the specified address.
Example:
4.2.1 Indexed Variable Address
General Syntax:
@[tttt]oi1+k[!]o[min]o[max]
[i1] =variable address for pointer
[k] =constant
The actual variable address comprises the
contents of [i] and the constant [k]. It must be
ensured that the sum of [i] and [k] does not
exceed the valid range of values for the PLC.
The index register is defined in the same
message:
i1 = the first index definition found
i2 = the second index definition, etc.

BEST240-24-Z Editon 2/94 Page: 9
4.3 Input Limits
The operating panel monitors input variables to
ensure they are within an upper and a lower
limit. The input limits are programmed directly
after the variable address. A corresponding
error message from the text memory (message
1000 or 1001) is displayed if a value either falls
below the lower input limit or exceeds the upper
limit.
4.3.1 Indexed Input Limits
The limits can also be indexed, if the PLC
program is also to modify the input limits.
In this example, the max-limit is read from
register (data word or flag word, depending on
the PLC) 17 and the min-limit is read from
register 16.
The input limits are read in the same variable
format as the input variable (in the example as
a signed 16-bit number).
Index registers are defined in the same way as
indication variables. The limitation of 8
definitions per message applies here also. This
means that the number of possible variables is
reduced by one per index register. This applies
only to the current message - all other
messages may still contain the full 8 variables.
4.4 Variable Formats
The representation format of a variable is
specified as part of the variable definition. This
manual describes all of the formats supported
by the BEST operating panels. Because of the
large differences between the various PLC
types, each description lists the variable
formats actually possible for the PLC
connection.
4.4.1 Variable Format UNS
The defined data word is interpreted as an
integer without a sign in the range of 0 ...
65535. Only the keys 0 and 9 are accepted by
the input editor. The number of filler characters
must be between 1 and 5.
4.4.2 Variable Format INT or KF
The defined data word is interpreted as a
signed integer in the range of -32767 ...
+32767. The key [+/-] allows the sign to be
reversed. When programming the filler
characters, it must be taken into consideration
that one digit is required for the sign. The
number of filler characters must be between 2
and 6.
4.4.3 Variable Format IL or MD
Represents a signed 32-bit number. The
number of filler characters must be between 2
and 11. Two consecutive registers are
automatically read for PLC types which are only
provided with 16-bit registers (data words).

@idxo16!
@idxo17!

Page: 10 Programming the Operating Panel Editon 2/94
4.4.4 Variable Format BCD
The defined data word is interpreted as a 4-digit
BCD number in the range of 0 ... 9999. The
number of filler characters must be between 1
and 4. If the data word has been predefined
with nibbles >>9 by the PLC, they will be
represented by the characters A to F.
4.4.5 Variable Format BCDL or LNG
The defined data word is interpreted as an 8-
digit BCD number in the range of 0...99999999.
The number of filler characters must be
between 5 and 8. Two consecutive registers
(data words) are automatically read for PLC
types which are only provided with 16-bit
registers (data words). If the data word has
been predefined with nibbles >>9 by the PLC,
they will be represented by the characters A to
F.
4.4.6 Variable Format HEX or KH
The defined data word is interpreted as a 4-digit
HEX-number in the range of 0 ... FFFF. The
number of filler characters must be between 1
and 4. The keys 0 and 9 are accepted by the
input editor. The characters A ... F are
produced by simultaneously pressing the key
[SFT] and one of the keys 0 ... 5 (corresponds
to A .. F).
4.4.7 Variable Format BIT or KM
The defined data word is represented as 16
single bits. The number of filler characters must
be between 1 and 16. The keys 0 and 1 are
accepted by the input editor.
Example for an input variable:
Example for an indication variable:
The bit variable is read from register 10 and
represented from bit 7 onwards. The zero is a
dummy parameter used to identify the bit
variable as an input variable. It should be noted
that the bits that are not displayed are still read
and written back to the PLC unchanged when
the Enter-key is pressed. This can mean that
any modifications made by the PLC in the
meantime are cancelled.
After the character (!), indication variables
require an additional parameter for the start bit.
