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.

Unpacking the
PG 740
!
Desk-Top
Mounting
Unpack your PG 740 as follows:
1. Remove the packing.
2. Do not throw the original packing away. Keep it in case you have to
transport the unit again sometime in the future.
3. Check with the packing list to make sure no components are missing.
Caution
Risk of damage!
When transporting the unit in cold weather, when it may be submitted to
extreme variations in temperature, make sure that no condensation is
allowed to form on or in the unit.
The unit should be allowed to reach room temperature slowly before it is
started up. If condensation has formed, the unit should be left for
approximately 12 hours (with a temperature difference of -20° C to + 20° C
(-4° F to + 68° F)) before being switched on.
The PG 740 is usually mounted on a desk or table top. T o make working with
the PG 740 easier, it can be adapted as follows to the particular workplace:
1. Set the PG 740 down on the desk or table top.
2. Open the keyboard lock by pulling up the anthracite-colored handle.
3. Swing the keyboard down into position.

Changing the
Angle of
Inclination
With the keyboard open, you can incline the unit to any angle between 0 and
90° around the axis of rotation of its stand. Proceed as follows:
1. Swing the keyboard down.
2. Pull the extra support (Figure 2-3) out of the rear of the stand.
3. Incline the unit to the angle you prefer.

Figure 2-2 Changing the Angle of Inclination
Caution
!
Risk of injury!
There is a danger of the unit tipping over if it is set up without extra support
and at an angle of inclination of more than 15°. This could lead to personal
injury and also damage to the unit.
If the angle of inclination is greater than 15°, you must use the extra
slide-out support in the stand.

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.

Keyboard Labeling
The largest block of keys on the keyboard is the alphanumeric or typewriter
keyboard with all the keys for the letters of the alphabet, numerals and
special characters. The characters (letters, numerals and special characters)
are arranged in generally the same way as on a normal typewriter. However,
there are a number of special keys which have specific special functions for
the PG 740.
The keyboard has international labeling.

Backspace Key
This key moves the cursor one space to the left and deletes the
character at this position
Return Key
The Return or Enter key is used mainly to terminate a command
line in the operating system; that is, the command you have
typed in is executed when you press this key. For other uses of
this key, please refer to the user manual of the relevant
application program.
Caps

CAPS-LOCK Key
If you press this key, the middle LED at the top right-hand corner
of your keyboard lights up. All letters then appear in uppercase
and the upper of the two characters on the individual keys
applies. If you wish to type in lowercase letters in this position,
you must first strike the Shift key.
If you are using an international keyboard, you cancel this
function by pressing the CAPS-LOCK key again. The LED goes
out. If you have a German keyboard, you must strike the Shift
key to cancel this function.

2.5 Trackball

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.

Caution
Risk of data loss!
You must not remove the diskette as long as the access LED is lit.
Otherwise, you may lose the data on the diskette.
Do not remove the diskette until the access LED on the drive or on the front
of the PG 740 has gone out.
You can use a number of different hard disk drives in your PG 740. The
memory capacity of the particular type of hard disk can be found in the
Product Information Bulletin and SETUP program.

Self-Test
Every time the PG 740 is switched on or reset, the hard disk drive performs a
self-test, which is repeated during operation.
Whenever the hard disk drive is accessed, the access LED on the front of the
unit lights up.

Caution
!
Risk of data loss and damage to drive!
Drives are sensitive to vibrations and shock. Any vibrations occurring during
operation can lead to the loss of data or damage to the drive.
If you intend transporting the unit, switch it off, and wait until the drive has
come to rest (about 20 seconds) before you move it.

Preparatory
Measures
The PG 740 is easy to transport. Before transporting it, however, you should
take the following measures:
1. Switch the PG 740 off.
2. Unplug all connecting cables.
3. Close the covers protecting the ports and connections on the right-hand
and left-hand casing side panels.
4. Bring the unit into an upright position.
5. Swing the keyboard up and press it against the front plate of the unit.
Make sure that the latches on the left and right sides snap in.
6. Use the carrying handle if you only intend transporting the unit over a
short distance.
7. If you are transporting the PG 740 over large distances, pack the unit with
all its accessories in the carrying bag supplied.
Transport
2-20
Figure 2-17 Prepared for Transport
Despite the fact that the PG 740 is of rugged design, its internal components
are sensitive to severe vibrations or impact. You must therefore protect your
PG 740 against severe mechanical stressing when transporting it.
Use the original packing material if you have to ship the PG 740 from one
location to another.

Caution
!
Risk of mechanical damage!
Moisture or condensation in the unit can result in defects.
When transporting your PG 740 in cold weather when it may be exposed to
extreme variations in temperature, make sure that no moisture or
condensation can form on or in the unit.
The unit should be allowed to reach room temperature slowly before it is
started up. If condensation has formed, the unit should be left for about 12
hours (with a temperature difference of -20° C to +20° C (–4° F to +68° F))
before being switched on.
