3 Features of the AS-i PCI Board
The AS-i PCI Board of the Bihl+Wiedemann GmbH:
• ... contains two complete AS-i Masters with AS-i Control option (PLC), built as
a board for the PCI-bus.
• ... easy installation with "Plug and Play"
• ... is able to execute a control program1. It operates without taking an affect to
the performance of your PC. The other way round the control program runs with
a constant cycle time independent from the PC capacity required by other appli-
cations.
• ... exchanges data with the PC via Dual Port RAM (DPRAM).
• ... an event mechanism can notify the PC application about changes of the data
on the board.
• ... up to 4 AS-i PCI boards can operate in one PC system.
• ... is capable to generate an interrupt on the PCI-bus, for example if the AS-i
data changes.
• ... is able to detect a breakdown of the PC, if the built-in watchdog is activated
(The AS-i masters will change to the Off-line phase if the watchdog is not trig-
gered by a PC program).
• ... Advanced Diagnostics: to detect occasionally occuring configuration errors
and to judge the quality of the AS-i communication.
• ... the included driver makes it possible to use the AS-i PCI board with several
applications simultaneously.
1. The control functions is not available at the A²SI and SAP4 Programming- and Testtool (art. no. 1355).

4 Installation of the AS-i PCI Board
The "Plug and Play"-feature makes the installation of the AS-i PCI Board very
easy:
1. Switch off the PC.
2. Then just insert the board into a free PCI slot and connect the AS-i circuit(s).
3. The following pictures shows the possibilities to connect an AS-i circuit.
4. Now switch on the PC.
Windows 95/98:
If you have Windows 95 or Windows 98 you will be asked to insert the driver disk
for the AS-i PCI Board ("Windows 95/98 driver install disk for AS-i PCI Board"; this
is the disk 1 of the software AS-i Control Tools).
Then install the AS-i Control Tools (setup.exe on disk 1) and follow the given in-
structions.
Windows NT:
If you have Windows NT, make sure that are you logged in as administrator, then
just install the AS-i Control Tools (setup.exe on disk 1) and follow the given instruc-
tions.
Connection samples for the AS-i power supply:
In the wiring schemes above the current through the AS-i mas-
ter must not exceed 5 A.

5 Accessing the Data
5.1 Windows Device Drivers and DLLs
The AS-i PCI card comes with Windows device drivers for Windows 95/98/NT and
2000 (see chapter 3). In addition to that you can download the DLLs "asidrv32"
and "asipci.dll" from the Internet. These DLLs enable the user to write its own Win-
dows application. The use of these DLLs is described in the files "readme.txt" and
"aasidrv.h" that are also contained in the driver package "Windows drivers for AS-i
Masters (32Bit DLL)".
5.2 OPC-Server
Another possibility of data access is the use of the OPC-Server. The OPC-Server
is an easy possibility to use a wide variety of SCADA-systems together with the
AS-i PCI card.
5.3 Using the AS-i PCI card without the Windows Device Driver
The DPRAM of the AS-i PCI board is accessible both memory mapped and I/O
mapped. The PCI host system should provide ways (such as the PCI BIOS in case
of an IBM AT) to determine the I/O and/or memory base address and interrupt
number.
5.3.1 Identifying the Board
The following information is needed to find and identify the AS-i PCI board on the
PCI bus:
Vendor ID E159h
Device ID 0002h
Subsystem Vendor ID 0022h
Subsystem Device ID 0001h

5.3.2 Register Map
5.3.3 DPRAM Access
The AS-i PCI board uses a 1 kByte, byte-wide DPRAM. The access to this DPRAM
is done through a 16 byte window starting at offset C0h.
To select the window for a certain DPRAM_address, set the register "AUX pin da-
ta" at offset 03haccording to the following formula:
"AUX pin data" = DPRAM_address/16 + 128
In other words, bits 20to 25of "AUX pin data" determine the bits 24to 29of the
DPRAM address. "AUX pin data", bit 27should be set.
To access a certain cell of the DPRAM within the DPRAM window, read or write at
the following offset:
offset = C0h+ DPRAM_address mod 16 * 4
5.3.4 Interrupt Handling
Besides installing an interrupt handler on the PCI host and selecting an interrupt
source in the DPRAM, you have to set the "Interrupt mask" register at offset 05h
to 40hin order to enable interrupt generation of the AS-i PCI board.
If the AS-i PCI asserts an interrupt, bit 26of "AUX pin status" is set to zero. To ack-
nowledge the interrupt, set bit 27of "AUX pin data" to zero and wait for bit 26of
"AUX pin status" until it becomes ’1’. Afterwards, read the "Interrupt Event"
DPRAM cell to determine the interrupt source that caused the interrupt.
(If this is done within a interrupt handler, you should save and restore the contents
of the "AUX pin data" register in order to avoid switching the DPRAM window du-
ring DPRAM access of an other task.)

Device, Part 2:
If an AS-i Control program1runs, buffers C and D are occupied by the AS-i Control
user memory (flags).
6.2 AS-i Master Execution Control Lists
All data of the AS-i master may be read at any time out of the DPRAM (addresses
000hto 0AFhresp. 100hto 1AFh).
The only lists, that are read cyclically by the AS-i master are the output data image
ODI, the host interface flags (hi-flags)and the parameter image PI. All other lists
can only be written by using the mailbox commands.
The AS-i master writes cyclically the input data image IDI, the execution control
flags (ec-flags), the list of active slaves LAS, the list of detected slaves LDS and
the configuration data image CDI.
Additionally, the installed software string is updated.
Due to the internal processing of the output data image ODI, the user has to store
it inverted to the DPRAM.
While a control program1is running, it generates the new ODI, so the AS-i master
writes it to the DPRAM image.
6.3 Working with AS-i Control Programs
While an AS-i Control program1is running all output data that are written directly
to the ouput data image ODI are overwritten instantly by the AS-i Control program.
To write output data from the PC to the card you have to write these data to the
user flags. These user flags must be copied in the AS-i Control program to the out-
address size data access

puts. You can copy the data either bit-wise or with transfer-commands byte- or
word-wise to the outputs.
6.4 Mailbox Commands
To read and write the execution control lists that are not directly accessibly in the
DPRAM the AS-i PC card has four mailboxes. These mailboxes have to be used
as well if commands like "Change Slaveaddress" or "Store Configuration" shall be
executed.
Each mailbox consists of 16 bytes:
In addition to that there is a 128 byte buffer assigned to each mailbox.
The command is initiated by writing a valid command value to the first byte of the
mailbox. After command execution, the master overwrites the command with one
of the following values:
00h:ACK
successful command execution
FFh:NAK
an error occured during command exectution
Before the AS-i Master overwrites the first byte of the mailbox with NAK, it writes
an error message to the second byte of the mailbox:
00h:OK
no error occured
01h:NOK
error occured, no more precise diagnosis available
10h: Request
invalid command value was written to the first byte of the mailbox
12h:CtrlBuff
command is not allowed in this mailbox because buffers C and D are oc-
cupied by the AS-i Control user memory.
13h: NotImplemented
command is valid but not implemented yet
The following mailbox commands are available:

commands).
