2.1.4 PC56 Architecture
The continuing advances in processor technology have influenced the PC56
architecture. The speed at which new processors are introduced helped
determine that a sub-module approach be used in the design of the PC56. The
PC56 module consists of a two board stack, the ControlLogixTM board and the
CPU board.
The ControlLogixTM board contains the components necessary to communicate
with the 1756 backplane as well as all the physical interfaces on the front of the
module. The PC56 interfaces with the ControlLogixTM backplane through a
shared memory window and uses a PCI interrupt. The memory window and
interrupt are allocated by the system BIOS during the boot process.
The CPU board houses the processor, the PCI chipset and connector and the
Ethernet chipset. These components are most likely to change with new
advances in component technology.

3.1.1 Battery Enable/ CMOS Clear

PC56 ♦ControlLogix Platform Installing PC56
In-Rack Industrial PC
Page 16 of 33 ProSoft Technology, Inc.
January 28, 2008
Clearing CMOS Memory
Insert the jumper in the CMOS Clear position momentarily if you want to clear
CMOS memory and install the factory default BIOS settings.
3.1.2 Battery Enable
Place the jumper in the Battery Enable position to enable battery back-up of the
system Real Time Clock, CMOS Memory, and 512 KByte battery-backed SRAM.
If the PC56 is not going to be powered up for a long period of time, then it is
advisable to remove the Battery Enable jumper to prevent complete discharge of
the rechargeable battery.
3.1.3 COM1 Mode Select
Used to set COM1 serial port to one of the three configurations listed.
3.2 Inserting The Module
After you have checked the placement of the jumpers, insert PC56 into the
ControlLogixTM chassis. Use the same technique recommended by Allen-Bradley
to remove and install ControlLogixTM modules.
Align the module with the top and bottom guides and slide into the rack until the
module is firmly against the back plane connector. With a firm but steady push
snap the module into place. Check that the holding clips on the top and bottom of
the module are securely in the locking holes of the rack.
Note: Improper insertion of the module can cause unpredictable system behavior.
Note: If you are installing PC56 with other modules connected to the PCI bus. The peripheral
modules will not have holding clips. Make sure all of the modules are aligned with their respective
slots before you snap them into place.
3.2.1 Turn ON power
The PC56 will go through a POST routine that will check RAM and when
complete will set the OK LED to GREEN. All other LEDs will be blank or OFF,
unless your application sets them.

4 Reset, Auxiliary Timers and PCI Information
In This Chapter
Overview ...............................................................................................17
Using the USB Ports .............................................................................18
4.1 Overview
In addition to the standard PC system hardware, PC56 contains the ControlLogix
back plane interface circuitry with 512 MB SDRAM (upgradeable to 1 GB), an
82C54 timer, 512KBytes of battery-backed SRAM and a four character alpha-
numeric display.
This chapter describes the functionality of the special hardware contained in the
PC56 system.
4.1.1 Auxiliary Timer (WinCE Only)
The 82C54 timer shares a single PCI interrupt with the backplane support
hardware, therefore your software must support sharing of this interrupt if you are
going to use the timer in an application requiring the timer to initiate an interrupt.
The 82C54 timer can also be configured to use the Non-Maskable Interrupt
instead of a PCI interrupt. When the timer is configured to use NMI, then interrupt
sharing between the timer and back plane hardware is not required..
4.1.2 RESET: Functional Description
A hardware reset occurs when the PC56 is powered up or when the reset switch
is depressed. When a hardware reset occurs, the ControlLogix interface circuitry
is reset, and its interrupt is disabled. The 82C54 timer interrupt is also disabled.
4.1.3 PCI Configuration Base Addresses
The PCI configuration space contains the addresses allocated to the shared
RAM of the ControlLogixTM interface circuitry and the SRAM as well as other PCI
relevant addresses. The Vendor ID = 167Ch and Device ID = 0001h.

5 Troubleshooting
In This Chapter
FAQ.......................................................................................................19
If the system has been working properly, verify that the configuration has not
been modified. This includes peripheral PCI module installation, jumper settings,
BIOS settings, and cable connections. If needed, a module swap will verify a
faulty module. Make sure that the system configuration is correct, and that the
module you are replacing the suspect one with is a proven good one.
If the system has not been working properly, or you are installing the module for
the first time, then review the jumper and BIOS settings.
5.1 FAQ
Question:
What do the LEDs mean?
Answer:
BAT - If this LED is ON if the battery is low, or if the Battery Enable jumper is not
installed. As soon as power is applied to PC56, a low battery will begin to charge
and the BAT LED will return to the OFF state within minutes. Twenty hours of
continuous, powered-up operation will fully charge the battery.
USR - This LED is under program control and can be set to RED, GREEN, or
OFF. Review the installed software program guide for information and state
definitions.
OK - On power up, this LED is set to GREEN. During normal operation, if there is
a problem communicating with the ControlLogix backplane it will be set to RED.
This LED is under program and API control. It is sometimes referred to as the
status LED. Refer to your application and the API manual for information.

Question:
How can I tell if a communications port is working properly?
Answer:
There are two LEDs associated with each communications port: the top one is
green and the bottom one is yellow:
GREEN: Receive LED. This LED will momentarily turn ON when the serial port is
receiving data from another device.
YELLOW: Transmit LED. This LED will momentarily turn ON when the serial port
is transmitting data to another device.
Question:
Is PC56 slot dependent?
Answer:
No, but some consideration should be given to making room for any peripheral
modules you are plugging onto the PCI bus.
Question:
Does the order I plug the PC56 peripherals on to the PCI bus matter?
Answer:
The PC56-IDE module, if used, should always be installed in the first slot to the
left of the PC56 (Slot 0). Slot locations are numbered 0 through 2 starting at the
first slot location to the left of the PC56. The PCI slot assignment jumper for each
PCI peripheral module should be installed to match its corresponding physical
slot location.
Question:
What is the maximum number of peripheral PCI modules I can plug onto PC56?
Answer:
Three unless otherwise specified.
