The IPP 144 - 40 (Industrial Process Printer) is a device
designed for outputting text and data, i.e. measured values,
machine and process states, error messages, production
data, etc.
Two application examples:
.
Installation
68 +0,7
138 +1
The paper reroll mechanism is inserted into the DIN size
panel cutout from the front side and is clamped against the
rear side of the switchboard using the mounting screws.
The switchboard thickness must not exceed 12 mm.
Make sure that the unit is properly mounted before
connection and power on.
62
.
If connected to a digital voltmeter, the IPP 144 - 40
records the measuring values (with date / time for the
E version).
Its integrated interfaces allow the use of the IPP 144 40 as a pripheral for all PLCs (RS 232C; RS 422;
RS 485).
The alphanumeric printer is a DIN size panel mounting unit
which is able to print line widths of up to 40 characters per
line. The 14 m paper roll (commercial grade document proof
thermo paper) is located inside the housing and can be
easily replaced by means of a swivel type front panel. An
end of paper indicator lights up if the printer runs out of
paper.

II Paper reroll mechanism IPP - AW
1. General information
Up to 31 devices
Each printer is addressable, wich allows the connection of
up to 31 devices to one sender device via a data line at the
RS 485 interface, e.g. to a PLC.
Basic version The basic version provides one serial interface capable of
receiving only. Return (handshake) messages to the sender
IPP 144 - 40
are sent via hardware line. Text and measuring values to be
printed must be transmitted from the sender device since
the basic version does not have an internal text memory.
Extended
The extended version IPP 144 - 40 E provides a second,
version
bidi-rectional serial interface capable of outputting return
IPP 144 - 40 E messages under program control in compliance with a
protocol. In addition, this model includes a text memory
capable of storing up to 15 texts which are called by
specifying the corresponding text number. Moreover, date
and time may be printed with texts and data.
It is not possible for the user to upgrade the basic version to
the extended version; the extended version is a different
factory version.
Parallel Interface (PI)
Both versions may be optionally equipped or upgraded with
a parallel interface (BCD / Centronics)
(IPP 144 - 40 PI or IPP 144 - 40 E PI).
4
The IPP - AW is a paper reroll mechanism designed for
use with the IPP 144-40. It has been designed to match
the printer in colour and style. It is preferrably installed
directly underneath the printer. The printed paper is automatically wound on a drum by a motor. A swivel front panel
allows easy paper handling.
The paper reroll mechanism is a DIN size panel mounting
unit. It is supplied with power and controlled via the
connector cable which comes with the unit and which is
connected to connector 12 of the IPP 144-40 (see chapter
3). An LED indicates the ready status. Deoending on the
distance between the two devices at least the last 9 lines
printed remain visible.

8.3.2. Coupling of IPP 144-40 with a DAA message
display to print fault messages.
Messages can be issued by all DAA type B and C
versions. (The A version DAA are not capable of outputting
data but only of displaying them since there is only one
serial interface available which is used to receive data).
The connection of the printer is made via the interface II
(RS 232 C) of the DAA. The printout is normally triggered
by a control device (e.g. a PLC) with a strobe signal
(strobe T) via the terminal strip for control inputs (parallel
interface) at the DAA.

8.3. Connection Examples

Installation
8.3.1. Connection of the IPP 144-40 E to the
DPM ... MF for the insertion of
measured values into texts.
68 +0,7
138 +1
The IPP 144 - 40 fits into a DIN standard panel cut-out.
It is inserted into the switchboard opening from the front side
and is fixed against the switchboard rear using mounting
screws.
The switchboard thickness must not exceed 12 mm.
The configuration requires the E version with PI option installed. Since the standard version of the DPM ... MF is already equipped with 2 alarm outputs (open collector), these
can be used for the switching from one text to another.
The printer receives the measuring values via interface I /
RS 232 C (also possible via interface II); the text is selected
via the parallel interface. The relevant interface is the
interface for which the parameters have to be set in the
menu program. The recommended configuration is: 8 data
bits, no parity, 1 stop bit, 9600 baud. With 7 bit, no parity,
the sender must be set to
2 stop bits.
CR (carriage return) transmitted from the DPM ... MF with
each measuring value starts the printing of the text. The
space for the the measuring value must be reserved within
the text during text entry into the printer by „Ctrl V“.

Interface II
It then searches its text file, starting at Text No. 1, and
prints out that number of pre-stored texts where variable
fields have been reserved and inserts the variable data in
sequence. During the search, any texts without variable
fields that it finds before, or amongst, texts in the file with
variable fields are also printed.
RS 232 C
When the printing is complete, the IPP E resets itself and
is ready again at Text No. 1.
For examples refer to page 60.
General comments:
Each message can now contain up to 40 ASCII characters
in a variable field. During text programming <Ctrl V>
automatically reserves 6 spaces and during printing
variable data will be inserted from this point. Therefore, the
pre-stored text should have adequate spaces to accept the
data to be printed. The data will overwrite stored text if
there are not enough spaces.
It is not necessary to mark a „text block“ with
<Ctrl X> <Ctrl Y> during programming.
The PI option, if fitted, will not function while this mode is
selected.
The „print interval“ function cannot be combined with this
mode.
While this mode is selected the normal
<Ctrl C> Text No. <CR> method to print individual
pre-stored texts does not operate. The two modes cannot
be mixed.
Since there is a maxima of 15 pre-stored texts, any input
data which exeeds this limit will be ignored.

Explanation concerning the signal names under RS 485
The names A, B, C correspond to the
EIA 485 - standard:
inaktive or logical „1“; A > B

If an interface does not comply with that standard,
the connections of A and B must be interchanged.

No means normal operation as before - using the PI
interface, if fitted.
How does it operate ?
Each block of variable data is market by <CR>. The
IPP... E takes and holds this data. After the last <CR> is
received it waits about 2 seconds and then counts the
number of <CR> markers it has received.

Note: Characters will be printed only up to 7F (HEX).
Timing
Note:
If all of the control inputs L, M, N and P are open, the
serial interface operates as in default mode, i.e. everything
transmitted is printed.
Wildcards
During text entry, in default mode up to six characters are
reserved automatically (see chapter 6.4.) for the printing of
measured variables; however, up to 10 digits may be printed.
These additional digits require additional blanks to be
inserted at text entry time, because otherwise
characters to the right of the wildcards would be overwritten. E.g.:
OIL TEMPERATURE X X X X X X
°C
2 additional blanks
„Ctrl V“ plus wildcards
If the wiring is correct, a measured value is printed:

5.3. Menu Program
Improved handshaking for pre-stored texts
All functions of the IPP 144 are set via menu program
using the ENTER and SELACT keys and are saved when
the user quits the program.
From then on the IPP 144 automatically uses these
parameters.
With the software (V 502,2) the printer now sets RTS at
„busy“ (and / or the signal „XOFF“ is transmitted) while a
pre-stored text is being printed.
This hardware (or software) handshake can be used to
control the data transmission and prevend rapid text calls
being lost or overwritten. When the printing of pre-stored
texts is complete, RTS is reset (and / or the signal „XON“ is
transmitted).
The possible settings are explained in chapter 6.
Entering
the menu
program
Press the MENU / SELECT key for approx 3 s.
The IPP reacts by printing
„ACTUAL PARAMETERS ?
PRESS ENTER“
Without handshake the following can occur, if the text calls
are sent in too quickly:
Data input:<Ctrl C> 1 <CR> <Ctrl C> 7 <CR> <Ctrl C> 11 <CR>
Actual print-out
Machine No. TREE

is used to control the data transmitter:
Data input: <Ctrl C> 1 <CR> <Ctrl C> 7 <CR> <Ctrl C> 11 <CR>
Print

Print interval
(serial)
During the presed wait delay the interface is not ready to
receive. After expiry of the wait delay the RTS signal (or
XON) becomes active again and requests the subsequent
transmission.
The next interval begins upon receiving of <CR> or
<CR + LF>,
< LF > on its own is not accepted.
XON / XOFF
The menu program Change Parameters can be called in
one of two ways:
•
•
Without prior printing of the current parameters:
Press both keys following ACTUAL PARAMETERS ?
With prior printing of the current parameters:
Press both keys following CHANGE PARAMETERS ?
The program is terminated by simultaneously
pressing ENTER and SELECT.
Following the printout * END * all modified
functions are saved.
Quitting
the menu
program
The report function printer ready / not ready are handled
by this protocol if no handshake lines are connected
(RS 232 C, RS 422 or RS 485).
XON
is transmitted if the IPP 144-40 E is ready to
receive.
XOFF
is transmitted if the IPP 144-40 E is not ready
to receive (see above).
If there are no keys pressed over a period of approximately
3 minutes, the program is terminated automatically and
any modifications made are not saved.
Note:
If the IPP 144-40 E is not ready to receive, it transmits
this character just once, not continuously.
No adjustments have to be made, this protocol always
runs parallel to the hardware handshake.

7. Functional Description
6.Adjustments
7.1. Start Printing
6.1. General Functions
To start the printing, the IPP 144-40 expects either one of
the characters
<CR> Carriage retum, Enter
und
<LF> Line feed.
Valid combinations are:
<CR>, <CR> + <LF>, <LF>.
Note:
Both combinations <CR> + <LF> and <LF> + <CR>
create two line feeds.
<LF> by itself has no effect combined with other control
characters (calling text, send clock, start print intervall see following sections).
The various functions and device parameters are selected
and set via the menu program (see chapter 5.3.).
The appendix contains a summary.
The are 2 operating modes:
ONLINE:
The device is ready to receive.
OFFLINE: The device is not ready to receive.

7.2. Adressing
Each IPP 144-40 / IPP 144-40 E printer is addressable.
Thus, several printers can be supplied with different data via
one data line.
Up to 31 printers can be connected by one sender device
(e.g.
a PLC). The respective address is set in the menu program.
•
NORMAL:
•
INVERTED: The printout is made top down, the last
print line is at the bottom. In this case the
printout is in the proper order after the
paper has been torn off.
•
Note:
- Standard interface RS 232 only permits 1 sender /
1receiver - do not connect more than 4 IPPs as
receiver.
- Only interface RS 485 allows up to 32 receivers.
38
The printout can be read during printing,
the last print line is at the top.

Interval
The printing of measuring values can be carried out under
internal timer control.
Setting range: 10 s ... 24 h in steps of 10 s.
The interval starts after the printing of the line received last.
For the Centronics interface it is not possible to specify
an interval.

Up to 31 printers may be called from one sender (e.g.
a PLC). The respective address is set in the menu program.
For more information see chapter 7.2., Adressing !
24. 06. 98
Eventually, the current date is printed.
Note:
Incorrect entries, e.g. day 33 of the month, will not be
accepted by the printer.
Instead, it starts over at the base value 00.

6.3. The PI Option
BCD Interface
Numerator
This feature prints a three digit line numbering (1 ... 999).
So:
•
EXTERNAL RESET:
The numbering is printed continuously. The line number is
reset to 0 if during a strobe pulse there is a low signal at
pin 13a.
In EDIT mode:
<Ctrl A> <Ctrl X> text no. <CR> text no. <CR>
<Ctrl A> text no. <CR> text no. <CR>
...
.
<Ctrl A> <Ctrl Y> text no. <CR> Text <CR>
EXTERNAL CONTROL:
If pin 13a is open (high signal), there is no line number
printed.
The printing starts at number 1 if pin 13a is set to low
signal.
It is continued while pin 13a remains low.
Unit
In addition to the numeric measuring values, a measuring unit
may be printed (e.g. mm or kV).
The are 2 ways of setting the unit: in the menu program or via
the control lines.
MENU:
There are 31 selectable units:
A; V; g; m; mA; mV; mm; m/min; µA; kV; kW; kp; Hz; °C;
%; W; kW; kVA; kHz; cosj; °F; °K; Upm; MW; bar; kWh;
l/min; N; kN; cbm/h; ppm CO 1).

•
In FILE mode:
<Ctrl X> text no. <CR> text <CR>
text no. <CR> text <CR>
..
.<Ctrl Y> text no. <CR> text <CR>
The text within a text block must have continuous numbers.
To delete text within a text block without creating a blank
line, the text numbers following the deleted line must be
decreased by 1 to move them forward.
This is not done automatically but has to be entered
manually.
Refer to page 46, 47, 48 und 60.
Call a

EXTERNAL:
Via the control lines F, G, H, K , 15 units can be selected.
The codes are listed in chapter 4.4..

30
The 2 underlined captions can be user specific and set at the factory.
35
Reserving
space for
measured
variables
In order to be able to insert measured values (variables) into
text afterwards, the location within the text must be market
using „Ctrl V“, which reserves 6 spaces into which any
characters may be entered, since they are overwritten at a
later time anyway; they are merely wildcards.
Example:
Entry:
TEMPERATURE <Ctrl V> XXXXX °C <CR>
<Ctrl> counts as one digit, so you only have to enter 5
wildcard characters.
The printout would look like this:
TEMPERATURE 263,45 °C.
6.4. Version E (IPP 144 - 40 E)
Text Entry
Text can only entered via interface II, not via the parallel
interface.
The maximum text length is 40 characters; if the text
length exceeds 40 characters, only first 40 characters are
saved.
Text may be input via any device capable of sending ASCII
characters, e.g. programming devices, terminals, keyboards or personal computers.
The text entry program is called via „CHANGE PARAMETERS“ (see chapter 5.3.) and „TEXT INPUT YES ?“.
•
Creating
a text block
A text block is created by combining several texts.
In the first place, the interface parameters of printer and
input device must be adjusted to each other:
PLEASE SELECT SERIAL PARAMETERS
! ! ONLY FOR TEXT - INPUT ! !
A text block can be printed in a single call.
The baud rate limited to 1200 baud.
To achieve this, place beginning and the end of the text in
brackets at entry time. Use the control characters:
Ctrl X = opening bracket
Ctrl Y = closing bracket
(After quitting the text entry program, the printer resumes
its previous functions.)
•
Differences between the modes „EDIT“ and „FILE“:
1)
FILE: There is a device available
(PC etc.) which has
its separate editing software (PC TOOLS,
WORD etc.1)) which can be used to modify the
text prior to the transmission. The transmission
includes the entire file and all texts.
EDIT: There is a keyboard or a terminal available;
modifications of the text are made using the
<BS > (Backspace) key or the arrow keys. Any
text entered is immediately printed for checking
purposes.
