The protective grid can also be removed, but you will have to use a little
force. Since the filter is replaced while the PC is operating, the protective
grid protects you from injuring yourself on the sharp edges of the fan and
prevents the filter pad from being sucked into the fan.
Caution
!
When the fans are operating, particles can be drawn into the system unit.
The protective grid may only be removed with the PC switched off.
1.3.2Removing the Protective Sliding Cover
Notes
Please note the following if the protective cover has to be removed:
When the fan cover is in place, the protective cover can only be moved to
the left as far as it will go. In this position, in case you forgot to move the
protective sliding cover back, a limited amount of air can still be drawn in.

Real-time Clock

Battery Voltage
Too Low
Changing the
Battery
A backup battery powers the real-time clock even after the PC is switched
off. In addition to the time of day, all information about the SIMATIC PC
(configuration) is stored. If the backup battery fails or is removed, these data
are lost.
Because of the clock’s low power consumption and the lithium battery’s high
capacity, the battery can provide backup power for the real-time clock for
several years. Therefore, changing the battery is only seldom required.
If the battery voltage is too low, the current time setting is lost and a correct
configuration can no longer be guaranteed.
In this case, you must replace the battery. The battery is located underneath
the bus board.
To change the battery, please proceed as follows:
1. Switch off your PC and unplug all connecting cables.
2. Open the unit as described in Section 1.4.
3. Remove the drive support.
4. Now replace the backup battery, which is attached to the motherboard by
a short length of a cable.
!
Resetting SETUP
5. Reassemble the drive support and close the unit.
Caution
You may only replace the lithium battery with an identical battery or a
battery type recommended by the manufacturer.
Dispose of used batteries in keeping with local regulations (special waste). If
returned to the manufacturer, the battery materials can be recycled (Order
No.:W79070-G13212-S2).
After having changed the backup battery, you have to reset the configuration
data of your PC using the SETUP program.

LPT1 Printer Port
The parallel port offers three transmission modes: SPP, EPP, and ECP. The
SPP mode (Standard Parallel Port mode) is the standard mode which is
usually used to trigger or address a printer. Both EPP (Enhanced Parallel
Port) and ECP (Extended Capabilities Port) are transmission modes which
permit data transfer rates of 2 up to 2.4 Mbytes/s. Such rates require I/O
devices which support these new modes.
Both modes are used, for example, for converting a parallel port to an SCSI
or to an IDE port. Each mode has an individual pinout.

2.9Hardware Addresses
How Memory
Decoding Works
The memory address area of a Pentium CPU has a capacity of 4 Gbyte.
Together with the 64-bit-wide CPU data bus, the CPU is equipped with
29 address lines (A3...A31) and 8 bus enable lines (BE0...BE7) which encode
the non-existent byte address lines A0, A1 and A2. The CPU address bus is
mapped via system controller (TSC) on the PCI address bus. Memory
addresses from 0000 0000h to 0009 FFFFh (640 Kbytes) and from 0010
0000h to 07FF FFFFh (127 Mbytes) are not included.
The ISA bridge maps the ISA address bus exactly once on the PCI address
bus via the PIIX (PCI ISA IDE accelerator) block. The ISA address bus for 8
bit modules covers the address area from A0 to A19 which corresponds to the
CPU addresses from 0000 0000h to 000F FFFh (1 Mbyte). The address bus is
extended with the address lines A20...A23 for 16-bit ISA modules and
therefore addresses from 0000 0000h to 00FF FFFFh (16 Mbytes).
Special memory read/write signals which are only activated in case of a logic
zero level of the address lines A20, A21, A22 and A23 make the distinction
between the 1 Mbyte and the 16 Mbyte ISA address areas.
If the CPU references address areas which are occupied by the main memory,
ISA bus control signals do not occur; that is, ISA bus modules within this
memory area are not referenced. In the reverse case, an ISA bus master
cannot reach addresses higher than 16 Mbytes. In order to gain a larger
address area than the memory address area with a maximum range of
640kByte to 1 Mbyte, different decoding holes in the Pentium programming
device motherboard are provided for dual port RAM extensions:
The CPU address area FFF8 0000h to FFFD FFFFh (512 k-128 k BIOS =
384 Kbyte) is mapped in the ISA address area 00F8 0000h to
00FD FFFFh and is always referenced in the CPU address area. Decoding
the address lines A24 to A 31 which do not exist on the ISA bus is
fulfilled by special hardware located on the motherboard.
1 Mbyte of memory address area can be assigned to the ISA bus in the 16th
Mbyte. This option can be activated/deactivated in the SETUP procedure.
During the division of the address areas, a distinction is made between the:
Memory address area and
I/O address area
Different read/write signals (I/O, WR, I/O RD, MEMR, MEMW) are used to
reference these areas. The following tables will give you the descriptions of
the individual functional groups for more details.

Autotype Hard Disk
The system parameters you can select in this submenu are usually stored on
the corresponding IDE drive and are read out of the IDE drive and entered in
the screen form after you have selected the option Autotype Hard Disk.
CD-ROM drives with IDE interface (ATAPI) are not entered in this
option.
If the option Autotype Hard Disk has been selected for a non-existent hard
disk, the procedure is canceled after max. 5 minutes because of timeout. The
current settings remain unchanged. It is therefore useful only to execute an
Autotype for existing system hard disks.
In the standard configuration of your PC, only one hard disk drive connected
to IDE adapter 0 is set as master. The setting of the option Type for all other
hard disks is [none].
In some cases it might be necessary to modify the suggested hard disk
parameters. Select the corresponding menu option for this purpose and
choose the desired value using the [+] and [–] keys. Enter [none] as Type if
no IDE hard disk or IDE CD-ROM has been installed. Enter a number from 1
to 39 to use a predefined hard disk type.
For user-defined hard disk types enter “user” and set the parameters for the
options Cylinders, Heads, Sectors/Track, WritePrecomp.

The cache memory is a fast intermediate memory located between the CPU
and the main memory (dRAM). If the feature has been enabled, repeated
memory access is not performed in the main memory but in the faster cache
memory. Some hardware or software might require you to disable your cache
memory, because the necessary program execution or waiting times become
too short due to the fast cache memory.

Monitoring Module
4.1Overview
Function
The SafeCard is a short ISA module. It is used as a monitoring module in
SIMATIC PCs. It monitors the ambient conditions and the operating mode of
the PC, it indicates operating modes and fail-state characteristics and controls
the fans.
SafeCards fulfill the following individual functions:
– Display status
– Monitor temperature and indicate excess or insufficient temperature
– Control fans
– Watchdog
– Serve as relay interface
– Battery-back the optional RAM 64kB
SafeCard messages can be transferred to applications by means of the
SafeCard driver. For installing the SafeCard driver under various operating
systems see the ReadMe.TXT file in directory C:\SAFECARD.

4.2Status and Diagnostic Displays
Monitoring Module
Overview
The diagnostic display for SIMATIC PCs is triggered by the SafeCard and
realized in the form of LEDs and a seven-segment display which are visible
on the operator panel mounted on the front of the device (varies according to
PC). Monitoring features are thus controlled and the current status of the PC
is indicated.
The operator panel is a separate component and only connected to the
SafeCard via a cable (see Section on “Operator panel”).
7-segment Display
Diagnostic port 80H- Output via 7-segment display:
Any write access to I/O port 80 is latched and its value indicated on the
two-digit 7-segment display. Every cold restart of the system (switch
ON/OFF) causes a detailed Power On Self-Test (POST). The POST
controlling steps are displayed as so-called POST codes on the 7-segment
display of the PC. The POST code descriptions are listed in Section 2.12,
“Diagnostic Messages” in the description of the motherboard.

4.3Temperature Monitoring / Display and Fan Control
Temperature
Monitoring
The temperature is measured via a sensor (NTC) and its status is indicated
via a green LED for normal temperature and via a red LED for errors. The
following conditions may cause errors:
Overrange of the acceptance limit of excess temperature
Underflow of the acceptance limit of insufficient temperature
Line break or temperature sensor unplugged
The temperature status can be checked at bit 0 of the I/O cell base address +
0Eh.
An error causes one of the following reactions:

T empLED changes from GREEN to REDalways
Canceling of T empBit in I/O cell base address + 0Ehalways
Relay output falls in quiet statealways

Note
Monitoring Line
Break
The NTC is a separate component and only connected to the monitoring
module via a plug connector. The NTC is equipped with cable and connector
and is part of the list of components. In order to guarantee correct
temperature monitoring, an NTC with a resistance of 10 kOhm is required
(SBS Order No. 57703-M103-G).
The NTC resistance is commuted to a SafeCard connector via twisted pair
cable. The errors “line break” and “connector unplugged” are additionally
monitored by open-circuit monitoring. A line break is signaled by a
temperature error.

4.4Watchdog (WD)
Monitoring Module
Function
Watchdog
Reactions
The watchdog monitors the program execution. The watchdog has the task of
informing the user about different reactions to a program crash.
When you switch on your PC, or when you execute a cold restart (hardware
reset) the watchdog remains in its quiet state, that means that it does not
trigger any reaction and the RUN LEDs remain dark. The description of the
I/O cell base address +0Eh triggers the watchdog. This is indicated by the
green RUN LED The watchdog status can be checked in bit 1 of the I/O cell
base address + 0Eh.
If the watchdog is not triggered within a preset time interval, the following
reactions occur:
ReactionOption
RUN LED changes from GREEN to REDalways
Canceling WD bit in cell base address + 0Ehalways
Relay output falls in quiet statealways
Initiating of PC resetto be set
Transmitting IRQ to PCto be set
If an executed watchdog is retriggered, the green LED is illuminated again.
Options are set via the configuration register bits 6 and 7.

Note
If you modify the watchdog time after the watchdog has been activated (that
is during watchdog execution), the watchdog is retriggered.
Marginal
Conditions
In order to secure the recognition of a fail-state from an interrupt-evaluating
unit which is connected to the relay interface, the SafeCard guarantees an
error hold time of at least 500 ms. This also applies if the PC is reset, for
example, after the watchdog has been executed.

Monitoring Module
Switching ON/OFF
Conditions
State Diagram
An external unit (for example, a call device, a horn or a signal lamp) can be
informed about the PC’s current system status via the relay output.
After switching ON or resetting the PC, the relay output starts operating (no
error occurs); that is, the relay coil is energized and the switch makes contact,
which means it switches to an active working position.
The relay is deactivated if the watchdog has been executed or excess
temperature occured. The coil is then de-energized and the switch breaks
contact (fail-state); that is, it switches to a de-energized position.
The relay output can also be controlled via bit 1 in the I/O cell base address +
0Dh.
Switching the relay from fail-state to error-free status via the software is
impossible if a fail-state occurs (that is temperature error or watchdog
executed).
The following table shows you the operating status occuring and the
corresponding switch position.

The maximum capacity of the battery-backed RAM is limited to 64 Kbytes
because the PC’s memory area for ADD-ON components is very limited and
the addressing of the RAM should be located in the memory-mapped area.
The address area listed below applies to the programmer. The motherboard
mirrors the address areas FFF8:0000h to FFFF:FFFFh on to the 16th Mbyte
of the AT bus; that is, on the addresses 00F8:0000h to 00FF:FFFFh.
The base address is set via address switch S1 (on = switch closed).

The module is referenced via an I/O register. Four I/O addresses are occupied
(xxCh, xxDh, xxEh, xxFh). Only the backed-up RAM is located in the
memory-mapped area.
In order to avoid address overlaps, alternative addresses are available. These
are set by two address switches S2 and S3 (on = switch closed).
The monitoring features WD and Temp are provided by the register base
address + 0Eh.

Open-circuit and break-circuit working of the relay output can be defined via
the register base address + 0Dh. This also sets the status of the software LED
or causes a hardware reset of the PC.
The first write access to this register enables the watchdog, WD LED (also
called RUN LED) is set to green.
The watchdog is retriggered by additional write access. At the end of the
watchdog execution time, the watchdog is retriggered by another write
access.
