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.

Battery Power Supply for 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.

8.2 Interrupt 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.

ASCII Editor
B
Base Memory
Basic Package STEP 5
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.

Boot Diskette
Booting
The speed (in bits per second) with which information is transmitted over a data link.
BASIC Input Output System
A diskette which includes a boot sector, enabling it to load the operating system.
A loading operation which transfers the operating system to the main memory .

COM1 Port
COM2 Port
Configuration Files
Configuration Software
Cursor
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).

Drives
Drivers
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.
E
EPROM/ EEPROM 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.
