Advantages of
the PG 740
Compared to a PC with standard hardware and software, the PG 740
programming device of the SIMATIC family has numerous advantages:
You can develop, debug and document user programs for SIMATIC S5
and SIMATIC S7 programmable logic controllers with the PG 740
without the need for additional hardware or software.
The rugged design and functionality of the PG 740 make it particularly
suitable for use on site under hostile industrial conditions. The PG 740
meets the specific requirements of industrial environments, such as
noise immunity, compliance with the relevant standards, ruggedness,
simple transportation and startup.
The PG 740 can be set up and operated in a large number of different
ways and positions, and can therefore be used practically everywhere it
is needed.
The PG 740 has all the integral ports necessary for connecting it to
SIMATIC automation devices:
– Programming interface for SIMATIC S5 EPROMs and EEPROMs
– Programming interface for SIMATIC S5 and SIMATIC S7 memory
cards in credit-card format
– Interfaces for connection to S5 and S7 programmable controllers.
The PG 740 is supplied with all the necessary system and automation
software already installed on the hard disk.
Since MS-DOS and Windows are also already installed, you can, of
course, also use the PG 740 as a stand-alone workstation, and run all
the standard software available on the market that requires MS-DOS or
Windows.
The PG 740 has the power and expansion capability of normal PCs,
and can therefore also be used as a fully-fledged personal computer.

All keys on the keyboard are of the autorepeat type. That is, the relevant
character is repeated as long as you keep the key depressed.
When the keyboard is attached to the casing, it has an inclination of 6°, and
the middle row of keys is at a height of 30 mm. When the keyboard is
detached from the casing, its angle of inclination is 4.5° and the middle row
of keys is at a height of 27 mm. Ergonomically, these are the ideal positions
for the keyboard.

Trackball
Cleaning the
Trackball
The trackball serves as an input device for cursor control and menu selection
in many programs (with mouse operation). By moving the trackball, the
cursor can be repositioned on the screen.
By pressing the left-hand button, you set a marker. The right-hand button is
assigned differently according to the application. You can select objects or
items in a menu, and start functions with the trackball.
The trackball runs in a self-cleaning roller housing which is capable, under
normal conditions, of preventing dust collecting on the trackball and transfer
mechanism. However, you should clean the trackball from time to time.
Proceed as follows:
1. Switch off your programming device.
2. Remove the cover of the trackball housing by turning it counterclockwise;
for example, by inserting tweezers or a similar gadget in the holes in the
ring.
3. You can now lift the trackball out of its housing.
4. Wash the trackball with tap water to which a mild cleansing agent has
been added (Figure 2-14).
5. Clean the trackball housing (Figure 2-15).
6. Clean the rollers (Figure 2-16).
7. Dry the trackball and return it to its housing.
8. Replace the cover and tighten it by screwing it clockwise.

Suggestions for
Configuring TTY
(20 mA) Interfaces
Rules
In this section, you will learn how to connect your PG 740 to a programming
device or programmable controller over a point-to-point connection.
You establish a point-to-point connection by connecting the PG 740 to
another programming device or a programmable controller via
S a V.24 connection
S a TTY connection
Reliable data transfer depends on several factors. The data transfer rate you
can achieve depends on the distance, the type of cable, the type of interface
and any interference present.
You can reduce interference by choosing the right transmission cable and
connecting it properly, and observing the following guidelines.
S Use a shielded cable with a low line resistance (< 130 W / km) and low
capacitance (< 90 pF/m). T wisted-pair cables enhance immunity to noise
due to inductance. A low surge impedance results in reduced voltage
excursions and shorter charge reversal times. The surge impedance
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 be run together. Signal lines must
be installed as far away as possible from strong interference sources
(400 V three-phase power cables, for example).
S The active TTY interface with 12 V no-load voltage has been tested on a
1000 m (3300 ft.) long cable at a transmission rate of 9600 bps in a
normal noisy environment. If a shielded LiYCY 5x1x0.14 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 contaminating field of the interference source decreases exponentially
with the distance.

Battery Power
Supply for
Real-Time Clock
and Configuration
Battery too Low
Changing the
Battery
A back-up battery (3.6 V lithium battery) powers the real-time clock even
after the PG 740 is switched off. In addition to the time of day, all the
information about the PG 740’s configuration is stored in RAM. If the
back-up battery fails or is removed, all this data is lost.
Because the clock uses very little power and the lithium battery has a high
capacity, the battery can provide back-up power for the real-time clock for
several years.
If the battery voltage is too low, the current time and the configuration data
stored in the RAM are lost.
In this case, you must replace the back-up battery. The battery is located
behind the power supply module on the motherboard.
T o change the battery, proceed as follows:
1. Switch your PG 740 off, unplug the power cable and detach all connecting
cables.
2. Open the unit as described in Section 4.1.
3. Undo the three screws of the bracing between the motherboard and the drive
support.
4. Remove the power supply by undoing the two screws on its right-hand side
and the two screws on the motherboard.
!
Resetting SETUP
5. Unplug the power supply cable from the power supply.
6. Slide the power supply to the left as far as the stop. Y ou can now lift the power
supply out of the unit.
7. Now replace the back-up battery, which is attached to the motherboard by
a short length of cable.
8. Fix the new battery to the motherboard with a cable binder.
9. Replace the power supply and close the unit as described in Section 4.8.
Caution
Risk of damage!
You may only replace the lithium battery with an identical battery or a
battery type recommended by the manufacturer of your PG 740
(Order No.:W79084-E1003-B1).
You should dispose of used batteries in keeping with local regulations. If
returned to the manufacturer, the battery materials can be recycled.
If you change the back-up battery, you must reset your PG 740’s
configuration with the SETUP program (Chapter 5).

Figure 5-3“Hard Disk Drive IDE Adapter” Submenu
The parameters which you can select here are usually saved on the respective
IDE drive, and are read from the drive and entered into the form when you
select the option “Autodetect Hard Disk”. CD-ROM drives with IDE
interface (AT API) are not entered here.
If you select the option “Autodetect Hard Disk” for a hard disk which does not
exist, an abort is executed after a maximum of five minutes as a result of a timeout, and the existing entries remain unchanged. It is therefore only meaningful
to carry out an autodetect for hard disks present in the system.
In the standard configuration of your PG, only one hard disk is entered as the
master at IDE adapter 0. [none] is entered as the type for the other drives.
Under certain circumstances it may be necessary to deviate from the
proposed hard disk parameters. In this case, select the corresponding menu
option and then the desired value using the [+] and [–] keys. Enter “none” in
the option “T ype” if an IDE hard disk or an IDE CD-ROM is not connected,
or a number from 1 to 39 if a predefined type of hard disk is to be used.
Select “User” if you wish to define your own type of hard disk; you must
then additionally enter the hard disk parameters in the options “Cylinders”,
“Heads”, “Sectors/Track”, “Write Precomp”.

It may be necessary to disable the cache with certain hardware and software
because intentional program runtimes or delay times are prevented by the fast
cache.

Hardware Information
Memory decoding
function
The Pentium CPU has a memory address area of 4 Gbytes. The CPU has a
64-bit wide data bus, 29 address lines (A3...A31) and 8 bus enable lines
(BD0...BE7) which code the non-existent byte address lines A0, A1 and A2.
The CPU address bus is mapped on the PCI address bus via the TSC (system
controller). Excluded from this are the memory addresses from 0000 0000h
to 0009 FFFFh (640 Kbytes) and from 0010 0000h to 07FF FFFFh (127
Mbytes).
The ISA bridge via the PIIX chip (PCI ISA IDE accelerator) maps the ISA
address bus exactly once on the PCI address bus. The ISA address bus for
8-bit modules covers the address area from A0 to A19, corresponding to the
CPU addresses 0000 0000h to 000F FFFFh (1 Mbytes). For 16-bit ISA
modules, the address bus is extended by the address lines A20...A23 and
therefore addresses from 0000 0000h to 00FF FFFFh (16 Mbytes). The
differentiation between the 1 Mbyte and 16 Mbyte ISA address areas is
achieved using special memory read/write signals which are only activated if
the address lines A20, A21, A22 and A23 have a level of logical “0”. If the
CPU addresses areas which are occupied by the main memory, no ISA bus
control signals are generated. This means that an ISA bus module is not
addressed in these memory areas. On the contrary, an ISA bus master cannot
reach addresses above 16 Mbytes. In order to achieve a larger address area
for dual-port RAM extensions than the memory address area between
640 Kbytes and 1 Mbyte, special decoder hardware is provided on the
Pentium programming device basic module:
S The CPU address area from FFF8 0000h to FFFD FFFFh (512k - 128k
BOIS = 384 Kbytes) is mapped into the ISA address area 00F8 0000h to
00FD FFFFh and is always addressed in the CPU address area. Decoding
of the address lines A24 to A31 missing on the ISA bus is achieved using
special hardware on the basic module.

Hardware Information
Interrupt
Assignment
Priority
I/O Addresses of
the Interrupt
Controllers
The PG 740 uses two integral 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 programmed for the
software interrupt vector 0A H (IRQ 2) by the ROM-BIOS.
The interrupts are priority-scheduled in the reverse order of their numbering.
Interrupt IRQ 0 has the highest priority and interrupt IRQ 7 the lowest. For
triggering IRQ 2, interrupt IRQ 8 has the highest priority and interrupt IRQ15
the lowest. Interrupts IRQ 8 to IRQ 15 therefore have priority over interrupts
IRQ 3 to IRQ 7. The interrupt vectors are initialized and masked when the
PG 740 is powered up.
