The AD5143 intelligent communication module (referred to
as
"AD51") has two RS232C and two RS-422 interfaces and allows
multitaskprocessingof BASIC programs.
User application programs running in the AD51 allow the following functions:
(1) The A series peripheral devices can be shared.
The AGGPP intelligentgraphicprogrammingpanel
(GPP),
AGHGPLCD
handygraphicprogrammer
(HGP) or AGPHP
plasma handy graphic programmer (PHP) started up by the
SW-AD51P system disk (SW-AD51P) can be used the an I/O
console of the AD51 and allows AD51 programs anddata to be
stored on disk (and ROM (GPP only)). The VT-220 terminal can
also beused as an I/O console.

The AD51 reads data (e.g. complicated numerical operation,
function operation) from thePC and calculates and stores it as
required so thatthe PC

Connected with an I/O console (GPP/HGP/PHP orgeneralpurpose I/O console), personal computerand printer, the AD51
allows the operating status to be monitored and controldata
to be printed
1) Monitor display ......... Indicates the production status, operating conditions, fault definition, etc.
2) Keyboard entry .......... Inputs the production schedule, production quantity, operating procedure
anddata setting.
3) Print out ........... ....... Prints out the production program,
production results, daily report, fault
definition, program data,inspection
results and test results.
4) Clock function
The AD51 includes an on-board, 24hour, real-time clock with leapyear
compensation which allows data to be
transferred by the BASIC program so
that the time-of-the-day data may be
processedeasily.

3.2.2 System subroutines
System subroutines are machine code programs used for special
AD51 functions (for example PC CPU transactions etc.). They are
already written in channel 0 of the AD51 at specified address
locations.
System subroutineoperation is initiatedbyusingthe
"CALL"
command in the BASIC program.
Systemsubroutines on the AD51are shown in Table 3.3.

The AD51 uses a buffer memory fordata communication with the
PCCPU. (The buffer memory is not battery
backed.)
(1) Buffer memory addresses are OOOH to BFFH (3K words).
See the memory map in
Section 3.4.
(2) Buffer memory data is made upof
16 bits peraddress.
(3) The buffer memory is accessed by the AD51 using system
subroutines (SR2, SW2). For details, refer to Section 7.2.1.

(2) Requests for communication transactions with the PC CPU may
also come from other sources, these are listed below and are
processed in the same way as AD51 transaction requests. Only
one transaction may be processed per PCCPU scan so that a
delay of 1 to 5 scans is possible before the AD51 transaction is
processed if severalof these requests overlap. The following list
gives the transaction requests inpriorin/ order.

4. Optical or coaxial data link module in 3 hierarchy system

5. Processing request from AJ71C24-S3 or second AD51
Hence, if continuous processing requests are received from
the A6GPP and AJ71C2443,communicationbetweenthe
AD51 and PCCPU is only madeonceeverythree
scans.
(3) When a system subroutine is called which
accesses the PC
CPU there is a delay while the PC CPU prepares the appropriate data. During this delay time, the AD51 switches tasks to
optimize scan time. In the example shown below, threetasks
are executing subroutine which access the PC CPU. Task one
provides the first processing request to the PC CPU which
prepares the requested data. Duringthis delay the AD51
switches to task 2 which isunable to pass its processing
request to the PC which is still dealingwith the one from task
1. The AD51 therefore switches to task 3 for which the same
situation exists. Onlyafter task 1s requesthasbeen
fully
processed can task 2s request be dealt with. Similarly task 3
must wait untiltask 2 been processed. For details of othertask
switching, refer to the GPC-BASIC Handbook.

On some conditions, a considerable delay
will occur for
data transmission to the PC CPU which is not used with
the AD51 in MELSECNET.
Transmission time can be reduced by performing communication only between the AD51 and the PC CPUs used
with the AD51 (PC No. FF.) and using MELSECNET data

6.2.3 Program runs after an interrupt signal from
the fX CPU
Set the task start condition to "CPU INT" ( W U interrupt). The
program is then run when the rising edge of the AD51 interrupt
signal is received from the PC CPU.
For programming information see Section 7.4.
(1) Write the BASIC program so that "END" is executed as the
final instruction. When '!END" is executed the AD51 interrupt
condition is reset. The interrupt program will not run
again
until the rising edge of the AD61 interrupt signal is received
from the PC CPU.

(2)Only one task may be defined as PC interrupt start. More than
one will generallylead to "ORST" error.
6.2.4 Program runs at preset intervals in real time
Select starting condition "REAL TIME INT" (real time interrupt).
The real time interrupt interval (i.e. the time between interrupt
signals) should be.tonger than the total time taken for the interrupt
program to reach the END instruction including the time required
by other tasks. An "ORST" error is detected if a second real time
interruptsignal isgivenbeforetheinterruptprogram
has executed its END command.
POINT
1
For tasks other than the one started by the interrupt signal
from the PC CPU (Section 6.2.3), any system subroutine
must not be executed t o access the PC CPU within five
seconds after the PCCPU is run.
A PC down error will occur if the system subroutine is
executed within five seconds.

6.3.1
n
Key input mnmands
Key inputs (INPUTand INKEY commands) to the AD51 via one
channel (asspecified bythe ZlDV command) should onlybe made
to one task.
Since tasks are executed
in order of task numbers, any data keyed
in to a task canonly be readat certain intervals.If a key is pressed
and more than one task is waiting for data from the specified
channel, onlythefirst
task to execute the INKEY or INPUT
instruction will read the key input.
The other tasks will then continue waiting until a key is pressed
while they are being run.

(3) Note that with printers that use the CR code (ODH)to initiate
printing (KGPRE, K7PRE etc.), writing a comma (,I after the

6.3.4 OPEN and CLOSE commands
Note the following precautions when using the
OPEN and CLOSE
commands.
(1) The channel specified as that for the console by DIP switch
SW16 and the channel selected for the printer on the printer
setting screenare automaticallyopenedbythe
AD51 OS.
The communication mode f o r other channels must be set in
the user programusingthe
OPEN command. These two
channels default to closed.
(2) The OPEN command is used to specify the communication
control at the RS-232C or RS-422 port. 'It'also initializes the
AD51 sendandreceivebuffers.
Executing this command thereforere-defines the communication mode for the specified portand clears both AD51 buffers
at that port.
(3) The CLOSE commandinitializesthe
AD51 communication
control and buffers in the same way as the OPEN command
however in this case the port is left in a read/write disable
state.
r
I POINT I
Before
using
the CLOSE command, ensure thatthe
transmit buffer is empty be using subroutine "STC". Data
will be lost if the buffer is initialized whileit still contains
data.
_ _ _ _ _ _ _ _ _

(4) OPEN and CLOSE commands are common to all tasks.
Therefore, any channel opened
by one taskcanbe used in
subsequent tasks without having t o repeat the OPEN command.

(1) Whenspecifying the headdevice using a character
string variable, define the number of points
t o be read
after setting the head device. (Reason: The character
string variable overwrites the bits at the end of the
data with "0". This woulddeletethe"numberof
points" data if this was written
first.)
L
(2) The time check period in line 180 should be set in
accordance with the "number of scans required for

7.9 Interruptfrom PC CPU to AD51
The interrupt signal from the PC CPU to the AD51 is valid on its
rise (i.e. the AD51 waits for the leading edge of the
signal).
[How t o use]
To enable the interrupt facility, therelevant task should be set to
"start at interrupt from PC CPU" on the multi task setting screen.
The AD51 will then run that task when it receives the interrupt
signal.
Once it has been started the interrupt task will operate until the
END instruction is executed. The interrupt is re-enabled after the
END instructionis executed.
El

when X01 turns on.

7.10 Interrupt from AD51 to PCCPU
System subroutine "SIT" causes the AD51 to interrupt thePC CPU
and allows AD51 interrupt sequence programs to be executed.
The AOJ2CPU cannot be interrupted by the AD51.
The PCCPU has interrupt pointers, 116 to 123, which are assigned
tointerruptsignals
generated by special functionmodulesin
order of I/O allocation.
For details, refer to theCPU Unit User's Manual and Programming
Manual.
In the system configuration shown in Fig. 7.7, when AD51 No. 1
interruptsthe PC CPU, theinterruptprogram
designatedby
pointer 116 is executed. When AD51 No. 2 interrupts the PC CPU,
interruptprogram 117 is executed. (116 has higherpriority.)

(1) The AD51continues operatingin the event of "battery

buffer full error", or "PCCPU error".
(2) The receive buffer capacity is 511 bytes per channel.
Overflow data is ignored.
(3)When data is sentfrom one taskto thebuffer memory
and the buffer memorybecomes full, the AD51 switches tasks. After that task has run theAD51 checks the
buffer, if it is nowvacant the original task is allowed
to
continue and if it is stillfull the AD51 will switch toa
third task (where used). This checking and switching
procedure will continuefor 1 minute if thebuffer
remains full after which 1 byte of the excess data will
be deleted.
The one minute cycle isrepeated until there is no
excess data left (The 1 minute cycle time may be
charged using the SWB system subroutine.)
(4) Possible causes of send buffer full error
are as follows:

APPENDIX 1 Differences between AD5143 and AD51
The AD51-S3 differs from the
AD51 in the following points:
(1) The AD51-S3 allows communication with the other stations in
MELSECNET.
The other stations can
be accessed by specifying theMELSECNET PC No. atthe set dataheadaddress
of the system
subroutine which used to access the PC CPU.
(2) In addition to the AD51 system subroutines, the AD5133 has
the following system subroutines:
