3.6 PG 740 Connections (Point-To-Point Connections)

Point-to-Point Connection

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.

4.6 Back-Up Battery

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).

Autodetect Hard

Disk” Option

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”.

“Enabled” in the option “LBA Mode Control” (enabled, disabled) means that hard disk capacities greater than 528 MB are supported. The value depends on the drive and should only be set using the autodetect function.

The type of access to the drive is defined in the option ”32 Bit I/O”:

A cache is a fast intermediate memory located between the CPU and the main memory (DRAM). Repeated memory access operations are executed in the fast cache, and not in the main memory, provided the feature is enabled. 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.
