Advantages of the
PG 720
Compared with a PC with standard hardware and software, the PG 720
programming device of the SIMATIC family has numerous advantages:
S You can develop, debug and document user programs for SIMATIC S5
and SIMATIC S7 programmable logic controllers with the PG 720
without the need for additional hardware or software.
S The rugged design and practical functions of the PG 720 make it
particularly suitable for use on-site under tough industrial conditions. It is
extremely light and easy to transport. The PG 720 meets the specific
requirements of industrial environments such as noise immunity,
compliance with the relevant standards, ruggedness, simple transportation
and startup.
S The PG 720 is equipped with a battery allowing it to be operated without
a mains connection.
S The PG 720 can be set up and operated in a large number of different
ways and positions, and can therefore be used practically anywhere it is
needed.
S The PG 720 has all the integral ports necessary for connecting it to
SIMATIC automation devices:
– Programming interface for SIMATIC S5 memory submodules.
– Programming interface for SIMATIC S5 and SIMATIC S7 memory
cards in credit card format.
– Communication interfaces for connection to S5 and S7 programmable
controllers.
S The PG 720 is supplied with all the necessary system and automation
software already installed on the hard disk in compressed format.
S Since MS-DOS and Windows are also already installed, you can, of
course, also use the PG 720 as a stand-alone workstation, and run all the
standard software available on the market that requires MS-DOS or
Windows.
S In terms of performance and expansion capability, your programming
device meets all the normal requirements of a PC. This means that the
PG 720 can also be used as a fully-fledged personal computer.

Cleaning the
Trackball
The trackball is a pointing device for cursor control and menu selection in
many programs that support mouse operation. By moving the trackball, the
cursor can be positioned anywhere on the screen.
By pressing the left-hand button, you set a marker. The function of the
right-hand button depends on the particular application you are using. You
can select objects or items in a menu and start functions with the trackball.
The trackball is in a roller housing which normally prevents dust collecting
on the ball or transmission mechanism. Nevertheless, you should clean the
trackball at regular intervals.
Cleaning the trackball:
1. Switch off your programming device.
2. Remove the cover of the trackball housing by turning it
counter-clockwise, for example by inserting tweezers or a similar tool
into the holes in the ring.
3. You can now take the trackball out of its housing.
4. Wash the trackball in a solution of tap water and mild cleansing agent.
5. Blow any residual dust out of the trackball housing.
6. Dry the trackball and return it to its housing.
7. Replace the cover and tighten it by turning it in a clockwise direction.

Interfaces (20 mA)
Rules
In this section, you will learn how to connect your PG 720 to a programming
device or programmable control using a point-to-point link.
You can establish a point-to-point link by connecting the PG 720 to another
programming device or a programmable controller using
S a V.24 connection
S a TTY connection
T o ensure reliable data transfer, several factors must be taken into account.
You can reduce interference by choosing the right transmission cable and
connecting it properly and by observing the following guidelines.
S Use a shielded cable with a low DC resistance (130 W / km) (about 40 W kft)
and low capacitance (90 pF/m) (about 27 pF/ft). T wisted-pair cables are
less susceptible to noise and interference. A low DC resistance results in
reduced voltage excursions and shorter charge reversal times. The DC
resistance decreases with increasing conductor cross-section for the same
length of cable.
S The shorter the transmission link, the higher the maximum possible data
transfer rate.
S If there is an active sender and an active receiver at the same end of the
transmission link, the sequence of access priority to the transmission circuit
must be taken into account in order to achieve the longest possible
transmission link.
S Signal lines and power lines must not run together. Signal lines must be
installed as far away as possible from sources of strong interference (for
example, 400 V 3-phase power cables).
S The active TTY interface with a 12 V no-load voltage has been tested on a
1000 m (3300 ft) long cable at a transmission rate of 9600 bps in an
environment with normal levels of noise (field strength 3 V/m or 1 V/ft). If
a shielded LiYCY 5 x 1 x 0.14 shielded cable is used, reliable transmission
is possible over a distance of up to 1000 m (3300 ft). The AS511 protocol
(only one transmitter at a time) was used for testing.
Note
The interference field of the source decreases exponentially with the
distance.

Real-Time Clock
and Configuration
Battery V oltage
too Low
Replacing the
Battery
A back-up battery (3.6 V lithium battery) powers the real-time clock even
after the PG 720 is switched off. In addition to the time of day, all the
information about the PG 720s configuration is stored in RAM. If the
back-up battery fails or is removed, all this data is lost.
The clock uses very little power and the lithium battery has a high capacity
so that the battery can provide back-up power for the real-time clock for
many years and seldom needs to be replaced.
If the battery voltage is too low, the time of day and the device configuration
data in the RAM are lost.
In this case, you must replace the back-up battery. The battery is located
below the drive mounting.

8.2Interrupt Assignments
Hardware Information
Interrupt
Assignment
Priority
I/O Addresses of
the Interrupt
Controllers
The PG 720 uses the two integrated interrupt controllers of type 82C59 to handle
the 16 hardware interrupts (IRQ 0 to IRQ 15).
The INT output of the slave controller is connected to the IRQ 2 input of the
master controller. Interrupt 9 (IRQ 9) can be used on the bus for the assigned
interrupt 2 (IRQ 2).
In the initialization phase, IRQ is assigned to the software interrupt vector 0A
H (IRQ 2) by the ROM-BIOS.
The priority of the interrupts is in the reverse order of their numbering. This
means the following:
S Interrupt IRQ 0 has the highest priority and interrupt IRQ 7 the lowest.
S For triggering IRQ 2, interrupt IRQ 8 has the highest and IRQ 15 the lowest
priority. Interrupts IRQ 8 to IRQ 15 therefore have higher priority than
interrupts IRQ 3 to IRQ 7.
S The interrupt vectors are initialized and masked when the PG 720 is powered
up.
The following table provides you with an overview of the hardware
interrupts.

Access to the programs and data of a programming device can be protected
by passwords.
An application is a program which builds directly on, for example, the
operating system. Applications on your programming device are
MS-DOS/Windows, the STEP 5 Basic package, GRAPH 5 etc.
With an ASCII editor you can process (that is, edit) text files which are
stored in ASCII code (American Standard Code of Information Interchange).
The base memory is a part of the main memory. It is 640 Kbytes for all
programming devices. The size is entered in the SETUP menu under the
entry “Base Memory” and is not changed even if the memory is extended.
This is a software package which represents the basis for all other STEP 5
software packages. With the programming device (PG 720), this package is
used to program PLCs of the SIMATIC S5 family. The language used is
known as STEP 5.

Pressing and immediately releasing the left mouse button; this selects objects
or trigger commands.
The COM1 port is a serial V.24/modem interface. This interface is suitable
for asynchronous data transmission. It can also be used to connect printers
with a serial interface.
The COM2 port is a serial V.24 interface which can be used to connect a
mouse or a printer.
These are files which define the configuration after booting. Examples of
such files are CONFIG.SYS and AUTOEXEC.BAT.
The configuration software brings the device configuration up-to-date when
modules are installed. This is done either by copying the configuration files
supplied with the module or by manual configuration using the configuration
utility.
Collective term for mouse pointer and text cursor.
Cursor Control
Keypad on the keyboard for controlling the cursor.
D
Device
Configuration
The configuration of a programming device contains information on the
hardware and options of the device, such as memory configuration, drive
types, monitor, network address etc. The data are stored in a configuration
file and enable the operating system to load the correct device drivers and
assign the correct device parameters.
If changes are made to the hardware configuration, the user can change
entries in the configuration file using the SETUP program.
The diskette (floppy disk) is an external direct access memory on which all
Diskette
types of files and programs can be stored. The storage medium is a round
magnetic disk in a plastic cover to protect it from getting scratched.
The diskette drive (floppy disk drive) is used to store programs and data on
Diskette Drive
diskette (write access) or to load from diskette to the computer (read access).

Drop-Down Menu
The flat monitor of the PG 720.
Pressing and releasing the left mouse button very quickly twice in succession
without moving the mouse. This action is normally to open an object or
program.
The PG 720 programming devices are usually equipped with one hard disk
drive and one diskette drive.
These are programs which are part of the operating system. They adapt the
data from user programs to the specific formats required by the I/O devices
such as hard disk, printers and monitors.
In graphics-supported programs, a menu line is positioned on the top edge of
the screen. The menu titles contained in this line can be set either as
drop-down or pull-down menus. Drop-down menus “roll” down as soon as
the mouse pointer passes over a menu title. Pull-down menus only “roll”
down when the menu title is clicked on. Different functions can then be
called from these menus by moving the mouse and clicking on an item in a
menu.

Submodules
Extended Memory
These are plug-in submodules with EPROM/EEPROM chips. S5 user
programs can be stored on them. These programmed submodules are then
plugged in specially designed receptacles in the programmable controller.
A memory extension can be installed in a programming device to increase
the size of the memory.
