Compared with a PC with standard hardware and software, the PG 720
programming device of the SIMATIC family has numerous advantages:
SYou 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.
SThe 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.
SThe PG 720 is equipped with a battery allowing it to be operated without
a mains connection.
SThe 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.
SThe 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.
SThe PG 720 is supplied with all the necessary system and automation
software already installed on the hard disk in compressed format.
SSince 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.
SIn 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.

2.1 Setting Up the PG 720
Unpack your PG 720 as follows:
1. Remove the packing.
2. Do not throw the original packing away. Keep it in case you have to ship
or transport the unit again at some time in the future.
3. Check the packing list to make sure that no components are missing.
!Caution
Risk of damage!
Moisture inside the unit can cause serious damage.
When transporting the unit in cold weather, when it may be submitted to
extreme variations in temperature, make sure that the unit is allowed to
reach room temperature slowly before you switch it on.
If condensation has formed, this must be allowed to evaporate before you
switch on. If, for example, the unit is subjected to a temperature change from
–20°C to +20°(–4°F to +68°F) you should wait approximately 12 hours
before switching on the unit.
The PG 720 is used primarily on a desk or table top. To ensure a comfortable
working position, the PG 720 can be adapted as follows to suit the work
place:
1. Place the PG 720 on the desk or table top.
2. Open the keyboard lock by pulling up the gray handle.
3. Lower the keyboard into position.

With the keyboard open, you can incline the unit to any angle between 0°and
90°. To adjust the angle, proceed as follows:
1. Lower the keyboard into position.
2. Pull the support (Figure 2-4) out of the rear of the stand and if necessary
pull out the extra support hoop.
3. Incline the unit to an angle that will allow you to work comfortably.

Note
When you change the angle of inclination, make sure that the keyboard
cable is not trapped between the device and the stand.
!Caution
Risk of injury!
There is a danger of the unit tipping over if it is set up at an angle of
inclination of more than 15°without using the pull-out support. 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 pull-out
support and if necessary the extra support hoop in the stand.

Figure 2-3 Detaching the Keyboard
!Caution
Risk of tipping!
If the keyboard is detached, there is a risk of the unit tipping over. Before
removing the keyboard, make sure that you pull out the support from the
device stand (Figure 2-4) and pull out the additional hoop.
You detach the keyboard as follows:
1. Grip the keyboard hinges in the stand behind the keyboard.
2. Pull the locks in the middle of the hinge assembly towards the keyboard.
3. Pull the keyboard up and out.
4. Place the keyboard on a suitable surface, using the hinge assembly as a
stand.
You attach the keyboard again as follows:
1. Place the keyboard cable in the cable conduit in the stand.
2. Snap the keyboard hinges into the receptacles in the stand.
Note
When attaching the keyboard, make sure that the cable is lying correctly in the
cable conduit and is fixed in position.

When the keyboard is attached to the unit, its angle of inclination is 6°, the
height of the middle row of keys is 30 mm (about 1 inch). When it is
detached, the angle of inclination is 4.5°, and the height of the middle row of
keys is 27 mm. This is an ideal ergonomic design to allow a comfortable
working position.
If no table or desk is available, the unit can be operated on the floor. You can
adjust the casing and display through approximately 90ointo the horizontal
plane.

2.2 Moving the Programming Device
The PG 720 is easy to carry. Before carrying it, however, you should take the
following measures:
1. Switch the PG 720 off and wait about 20 seconds until the drives have
come to a complete stop.
2. Unplug all the connecting cables.
3. Close the covers protecting the ports and connections on the right-hand
and left-hand side panels.
4. Bring the unit into an upright position.
5. Raise the keyboard and lock it by pressing it against the front panel of the
unit. The latches on the right and left snap in. Make sure that both catches
are properly locked.
6. If you only want to carry the unit for a short distance use the handle.
7. If you want to move the PG 720 over larger distances, pack the unit and
all its accessories in the carrying bag supplied.
Figure 2-6 PG 720 Ready for Carrying
Despite the rugged design of the PG 720, its internal components are
sensitive to severe vibration or jolts. When moving the PG 720 you must
therefore make sure that it is protected from severe mechanical forces.
Use the original packing material if you have to ship the PG 720 from one
location to another.
