INTRODUCTION

The AR-B6016 is an intelligent TTL I/O card. It is onecard in the AR-B6000 series of single on-board pro-cessor I/O cards developed by Acrosser Technology.All of the cards in this series operate in combinationwith easy to use, high performance, industrial I/Osoftware.

The AR-B6016 card provides many I/O functions toreduce the host computer's workload. It has beendesigned to allow the host computer to read inputs orwrite outputs directly. Another important feature of theAR-B6016 card is that it has been specifically de-signed for easy software development. You may wishto write software commands to instruct the on-boardprocessor of how to handle special I/O operations.

For input signal control, the AR-B6016 card can be setto quickly poll all input signals and, if necessary,debouce the signal with a software command. TheAR-B6016 can generate an interrupt request signal tothe host computer to indicate an input signal wasactivated, thus instructing the host computer that itdoes not need to wait or poll for a signal.


For output signal control, the AR-B6016 card supportssafety output functions. (If you have pre-programmedany into your I/O control software. This is an importantfeature because it gives you the ability to control theoutput signals even if the host computer hangs-up, thusavoiding possible dangereous output situations.

In real time response operation, the AR-B6016 cansupport relative I/O operation commands which havebeen previously downloaded onto the on-board SRAM(battery backed-up) from the host computer. If thisfunction is used, most I/O operations will directly sharethe on-board processor without the host computer'sjudgement.(Available on version 2.0)

DIP SWITCH SETTINGS

There are two DIP switches on the AR-B6016 card.

nSW1 configures the I/O base port.nSW2 configures the interrupt.

SETTING THE I/O BASE PORT ADDRESS

SW1 selects the I/O base port from 200h to 3F8h.Each port address occupies 8 addresses and eachincrement is by 8 addresses. The relationship of eachbit on SW1 to each address bit is indicated below:

Address bus A9 : Always equal to 1Address bus A8 : SW1-6 selected (off=1, on=0)Address bus A7 : SW1-5 selected (off=1, on=0)Address bus A6 : SW1-4 selected (off=1, on=0)Address bus A5 : SW1-3 selected (off=1, on=0)Address bus A4 : SW1-2 selected (off=1, on=0)Address bus A3 : SW1-1 selected (off=1, on=0)Address bus A2,A1,A0 (3 bits) are used to select 8 addresses.

Example 1: Base port address equals 200h.

Example 2: Base port address equals 248h.

Example 3: Base port address equals 3E0h.


DEFINITION OF EACH PORT ADDRESS

To read/write data directly to I/O port:

Base_port+0 : Port 1 of I/O channel (read/write)Base_port+1 : Port 2 of I/O channel (read/write)Base_port+2 : Port 3 of I/O channel (read/write)Base_port+3 : Port 4 of I/O channel (read/write)

For software command handshake:

Base_port+4 : Command byte (write)Base_port+5 : Parameter/data 1 (write)Base_port+6 : Parameter/data 2 (write)Base_port+7 : Parameter/data 3 (write)Base_port+4 : Echo status (read)Base_port+5 : Echo data 1 (read)Base_port+6 : Echo data 2 (read)Base_port+7 : Echo data 3 (read)


SETTING THE IRQ SIGNAL

SW2 sets the IRQ signal. The IRQ signal is used byspecial software commands that are active.

If an urgent condition has just taken place, the AR-B6016 will generate 1 interrupt signal to the hostcomputer to instruct it that something needs to beprocessed immediately.

SW2switch1 switch2 switch3 switch4 switch5 switch6 IRQ

OFF OFF OFF OFF OFF OFF NoneON OFF OFF OFF OFF OFF 2OFF ON OFF OFF OFF OFF 3OFF OFF ON OFF OFF OFF 4OFF OFF OFF ON OFF OFF 5OFF OFF OFF OFF ON OFF 6OFF OFF OFF OFF OFF ON 7

If an interrupt subroutine was serviced, the host com-puter must clear the IRQ signal before it exits thesubroutine. This is done by writing data 80h to baseport+7 address. (base_port+7)

For example in Quick BASIC language, the commandline is written as:

OUT base_port%+7,&h80


CONTROLLING THE I/O CHANNEL

There are two ways to read or write to the I/O channels,one is to read/write to the I/O port directly the other isby using I/O software function commands that aresupported by the AR-B6016 card.

READ/WRITE TO THE I/O PORT DIRECTLY

You can directly read data from or write data to the I/Oport at any time. The read/write operation will not affectany commands that you have activated previously.

For example if you write data 55h to port 1 and readdata from port 3, you would write the following pro-gram: (in BASICA)

100 base_port%=&h200 :REM Initial base port address110 ip_value%=0 :REM Initial input value120 op_value%=&h55 :REM Setting output value130 OUT base_port%+0, op_value%

:REM Output data to port 1140 ip_value%=INP(base_port%+2)

:REM Input data from port 3


READ/WRITE TO THE I/O PORT WITH SOFWARECOMMANDS

If you use the software commands, the host computermust write the command byte and parameters in se-quence, and also read echo status and data.

When the AR-B6016 card accepts a command, (writ-ten by the host computer) it will take some time toprocess the command. It must first acknowledge thehost computer with result status and data. Then thehost must check the echo status reported by the AR-B6016. A standard, completed software handshakeprocess is written below:

Step 1: Write parameter byte 1 to base_port+5(if parameter byte 1 is required)



Step4: Write command byte to base_port+4 to instruct theAR-B6016 to execute this command start.

Step 5: Check if data in base_port+4 (echo status) is equal to0BBh. If yes, delay for about 200ms, then repeat step5 to re-check.

Step 6: Read data byte 1 from base_port+5(if data byte 1 is required)

Step 7: Read data byte 2 from base_port+6(if data byte 2 is required)

Step 8: Read data byte 3 from base_port+7(if dta byte 3 is required)

6. RESET (0Ch)

The reset command is used to reintialize the AR-B6016 card. After reset, the card will return to thesame status as the initial power on. It will:

n Set all I/O direction to input.n Set all output channels to 0.

(output is TTL level low)n Deactivate all software commands that were

previously activated.n Clear all data in the data buffer or queue.


830 OUT base_port%+4, &h0C 840 FOR i=1 to 40 850 echo_status%=INP (base_port%+4) 860 IF echo_status%=&hBB THEN 840 870 IF echo_status%<>&hAA THEN 1000

800 OUT base_port%+5, debounce_time% 830 OUT base_port%+4, &h10 840 FOR i=1 to 40 850 echo_status%=INP (base_port%+4) 860 IF echo_status%=&hBB THEN 840 870 IF echo_status%<>&hAA THEN 1000



AAh -- -- --


10h tt -- --

The time resolution is 10 ms. If tt = 0Ah, thedebounce time will be 10 ms x 10 = 100 ms.If the value of tt = 00h, it will disable the I/Pdebounce function.


8. SET WATCHDOG DELAY (11h)

In some control systems it is very dangerous if there isa problem with the host computer, such as a systemhang-up, when the outputs signals are active and cannot be controlled.To avoid this condition, you can instruct the on-boardprocessor to watch for output signals and start thetimer. If the timer is not continuously re-triggered at aspecified rate of time it will signal a timeout and theoutputs will revert to a pre-specified state that the hostcomputer expects.

tt = timeout during (00h-ffh)cc = channel number (01h-20h)The time resolution is 1 second. If tt = 0Ah andcc = 01h, the timer will be set to 1 second x 10 =10 seconds.When 10 seconds is the timeout, channel 1 (port1, bit 0) will be ON (active), the others will be OFF(deactive).If the value of tt = 00h, it is a 256 seconds timeout.(maximum)


AAh -- -- --


11h tt cc --


Example: (in BASICA) 800 OUT base_port%+5, timeout% 810 OUT base_port%+6,on_channel% 830 OUT base_port%+4, &h11 840 FOR i=1 to 40 850 echo_status%=INP (base_port%+4) 860 IF echo_status%=&hBB THEN 840 870 IF echo_status%<>&hAA THEN 1000

At any time, you can use the base_port+4 address forreading out valid data that the AR-B6016 card saved.If the byte you retrieved equals zero, then there is nodata. If the retrieved byte equals 0D0h, then the validnegative data is ready in the base_port+5 address. Ifthe retrieved byte equals 0D1h, then the valid positivedata is in the base_port+5 address.


D0h cc -- --

D0h : Negative data valid.cc = channel no. (01h thru 20h, 32 channels max)Positive data = Positive triggered data.Negative data = Negative triggered data.

Below is a sample program to check and retrievethe input trigger's data: (in BASICA)

850 echo_status&=INP(base_port%+4) 860 IF echo_status%=&hD0 THEN 1100

:REM Negative data valid 870 IF echo_status%=&hD1 THEN 1200

:REM Positive data valid 880 IF echo_status%<>0 THEN 1000 910 ....................... :REM Normal process ...1000 ....................... :REM Error process ...1100 input_data0%=INP(base_port+5)

:REM read out data ...1200 input_data1%=INP(base_port+5)

:REM read out data

D1h : positive data valid.cc = channel no.(01h thru 20h, 32 channels max)


2. SET BIT OUTPUT DELAY ON/OFF (31h)

This command is used to turn ON or OFF the specifiedoutput channel by the host computer. When the timertimes-out, the specific output will be automatically setON or OFF by the on-board processor.

ECHO STATUS CODE

If, at any time, the host computer reads the I/O addressof base_port+4 (echo status) or if it writes a commandto the AR-B6016, it will get a 1 byte status code. Thisstatus code informs the on-board processor of whataction has occurred.

STATUS CODE LISTINGS

1. 00h : No data2. 0BBh : AR-B6016 is busy processing a

command.3. 0AAh : Data ready and function OK for previous

command.4. 0EEh : An error was detected by the AR-B6016

while processing a command. Base+5 isthe error code.

5. 0D0h : Negative triggered data ready inbase+5, if input's negative triggerfunction is enabled.

6. 0D1h : Positive triggered data ready inbase+5, if input's positive triggerfunction is enabled.


ERROR CODE DEFINITIONS

00hInitial resetAfter intial reset, the first command will be ignored bythe AR-B6016 and will report this error code. It is usedto inform the host computer that the AR-B6016 hasbeen reset. All queue data has been cleared and all I/O functions have been deactivated.

01hCommand errorThis command is not currently available.

02hROM BIOS checksum error. ( maybe modified ordestroyed)

03hParameter byte 1 error (out of range or others).




06hTimeout error(If watchdog delay function is enabled)

07hReserved

08hWarning! I/O port does not exist error. Thiscommand will be ignored by the AR-B6016 card.

09hWarning! I/O port not suitable error. This com-mand will be ignored by the AR-B6016 card.
