4.3

COMMUNICATION SYSTEM

It is used to perform communication between the remote buffer and host computer. When the both are ready to operate after power on, the communication starts from the transmission of remote buffer and reception of host computer and then the transmission/reception is repeated.

n2t2 t3

0 < t2 < To n2 < No

Tx<t3<tp

(1) Approximately two seconds are required for the first request

after both of remote buffer and host computer are ready. However, when the CS signal is off, the first transmission is performed after turning on the CS signal.

(2) The minimum time period between bytes is determined by the

parameter Ti (msec) of SET command. There is no prescription of minimum time period between reception bytes.

(3) Switching from transmission to reception

Immediately the remote buffer side can be ready to receive signal. Start transmission within the parameter setting time (To sec) at the host computer side. When no response is obtained for the time period (To or more), an error occurs in the host computer. (Overtime)

-15-

4. PROTOCOL A B-63322EN-1/01

(4) Switching from reception to transmission

The remote buffer waits for Tx msec (parameter setting time) and moves to the transmission process after completion of reception. When there is no transmission after waiting another parameter (Tp seconds), it is considered that an error occurred in the remote buffer.

(5) Overrun on reception

When the RS signal is turned off by the remote buffer on reception of signal, stop the transmission within the overrun parameter number bytes by the host computer.

(6) Overrun on transmission

When the CS is turned off on transmission of remote buffer, the transmission is suspended within 3 bytes including that which is currently being transmitted.

When the line is recovered, it waits for transmission of SYN and is SYN wait status. The procedures are the same as those of initialization on power on other than continuation or SYN of host computer.

(1) Framing error (2) Overrun error (3) Parity error (4) Data Set Ready off (5) Buffer full (the transmission stop request is unacceptable.) (6) Time out (7) Number of retry times has been exceeded.

2) Reception error

Ignore the reception data and restart the reception of SAT command at the remote buffer side when the following errors occurs.

(1) Number of retry times exceeded

Number of RTY reception times + Number of retransmission by checksum error > Ne

(2) Command error

Message format error Reception of undefined command Reception of unexpected command

(3) Overrun

This results if the transmission stop request is not accepted and the reception buffer is overflown.

3) Reception during transmission Data received during transmission is ignored.

COMMUNICATION SYSTEM

The expansion protocol A is the same as the protocol A excluding the transmission of NC data. The expansion protocol A mode is initiated after the <GTD> is output to the host computer by the remote buffer according to the data request from the CNC side. The communication system is performed in the full duplex mode in the expansion protocol A. The NC data transmitted is packeted and is transmitted to the remote buffer by the host computer. Also, perform the reception process of monitor packet from the remote buffer.

DATA PACKET FORMAT

The NC data is transferred to the remote buffer using the following format by the host computer after receiving the <GTD>. When the NC data transmitted becomes multiple packets, the packets can be transmitted in order without waiting the response from the remote buffer by the host computer.

NC data

( "256*n" byte )

Calculation range of checksum

1) NC data

The NC data is the fixed length of “256*n” bytes and the n is specified with the parameter (byte position 55 to 56) by the <SET> command. The default value of n is 0. In the case of “n = 0”, the normal protocol A is used.

n = 0 : Normal protocol A n = 1, 2, 4 : Expansion protocol A

Packet

No.

(1 byte)

Checksum

(2 byte)

End code

(1 byte)

NOTE

Note that n is set to 0 automatically even if n is set to t he values other than listed above.

2) Packet No.

a) Effective packet : 30h – 39h (ASCII code)

Be sure to assign packet No. 30h to the first packet. If there is only one effective packet, assign FFh to the packet, since it is not only the first but also the last packet. If there is more than one effective packet, packet No. 30h is transmitted to the host computer by the remote buffer, along with the monitor packet <NAK> of retransfer request. Hereafter, the value incremented by 1 should be the packet No. However, the value next to 39h becomes 30h. If there is only one packet, the packet is both the first and the last; be sure to assign FFh. Also, when the loss or improper order of packet No. is detected, the improper packet No. is transmitted to the host computer along with the monitor packet No. <NAK>. When the checksum error is detected, the improper packet No. is transmitted to the host computer with the monitor packet <NAK> of retransfer request by the remote buffer.

-28-

B-63322EN-1/01 5. EXPANSION PROTOCOL A

b) End packet : FFh

The end packet is transmitted by setting the packet No. to FFh. The data part of end packet is considered to be the effective data. However, the end packet received after transmitting <CAN> ignores the data part. This allows the expansion protocol A mode to be ended and the normal protocol A mode is initiated. However, when the checksum error is detected at the end packet, the before packet No. +1 is transmitted as the end packet No. to the host computer with monitor packet <NAK> of retransmission request. (Note) The host computer should shift to the protocol A when the command of protocol A is received after transmitting the end packet.

NOTE

If FFh is assigned to the first packet, packet No. 0 is transmitted to the host computer with <NAK>, since this packet is the last packet.

c) Invalid packet : Other than above

Transmit this invalid packet with the dummy data of

“256*n” bytes when the time out may occur since time is required for editing of NC data transmitted by the host computer. The remote buffer is processed as an invalid packet.

3) Checksum

The checksum is obtained by adding the NC data to the packet No. in units of byte and then expressing the 1 byte data produced by neglecting the overflow above 8 bits out of the total value above using ASCII 2-byte code.

4) End code

The end code should be the ASCII code CR (0Dh).

5.3

MONITOR PACKET FORMAT

The monitor packets transmitted from the remote buffer to the host computer are shown as below. All packets have the fixed length consisting of 5 bytes.

1) Stop request

CAN (18h )

The stop request is transmitted to the host computer by the remote buffer when resetting the NC and stopping data reception by an alarm. Transmit the end packet (the NC is dummy) after transmitting the packet which is currently being transmitted and move to the normal protocol A mode when this packet is received by the host computer. If the end packet was being transmitted when the CAN packet was received, the end packet need not be retransmitted in response to CAN. Transmit the end packet even in the DC3 reception status.

Meaningless (20h )

Checksum ( 2 b y t e )

End code ( 0Dh )

2) Retransmission request

NAK ( 15h )

Packet No. (1 byte)

Checksum ( 2 b y t e )

When a check sum error is detected in the received packet, the retransmission request corresponding to the packet is transmitted by the remote buffer. The host computer should perform retransmission from the corresponding packet immediately after ending the transmission of packet which is currently being transmitted when it receives this packet.

End Code (0Dh )

-30-

B-63322EN-1/01 5. EXPANSION PROTOCOL A

3) Interruption request

DC3 (93h )

Meaningless ( 20h )

Checksum ( 2 b y t e )

The interruption request is transmitted to the host computer by the remote buffer when the reception buffer may become overflown. The host computer should interrupt the transmission and wait until the next monitor packet is received after completing the transmission of packet which is currently being transmitted when it receives this packet.

4) Restart request

DC1 ( 11h )

Meaningless ( 20h )

Checksum ( 2 b y t e )

The restart request is transmitted to the host computer by the remote buffer when there is space in the reception buffer after requesting interruption. The host computer should restart the transmission from the next packet following the interrupted one when this packet is received.

enough to handle arriving data, perform one of the following:

(a) Turn the CS signal of the remote buffer off. The

remote buffer stops data transmission within two characters including the character being sent. (See Fig. A.)

(b) Send a DC3 code to the remote buffer. The remote

buffer stops data transmission within the overrun, which will be explained later, from the point when DC3 is sent. To make the remote buffer resume data transmission, send a DC2 code to the remote buffer. (See Fig. B.)

(4) When the host computer completes data processing, turn

the CS signal of the remove buffer on. Then, the remote buffer sends the data following the previous data.

(5) When data transmission is completed, the remote buffer

sends the DC4 code.

6.1.2

When the CNC Alarm/Reset is Posted to the Host

When the remote buffer becomes ready after the power is turned on, the remote buffer turns the ER signal on, and keeps the ER signal on until the power is turned off. When an alarm occurs in the NC, the NAK code is sent to the host computer, and when the NC is reset, the SYN code is sent to the host computer. This is not performed, however, if the host computer is not ready for reception (each of the DR, CD, and CS signals is on).

the rate of data transmission from the remote buffer: (a) Turning off the CS signal for the remote buffer causes the

remote buffer to stop data transmission after transmitting a maximum of most two characters, including the character currently being transmitted. (See Fig. A.)

(b) Transmitting a DC3 code to the remote buffer causes the

remote buffer to stop data transmission, such that the amount of data transmitted after transmission of the DC3 code does not exceed the overrun. (See Fig. B.)

NOTE

If the RBETX bit of parameter No. 5000 is set to 1, method (a) cannot be used because, while the CS signal is off, a SYN/NAK or DC4 code is not transmitted even if CNC reset or a CNC alarm occurs. In such a cause, use method (b).

(4) For method (a) in step (3)

Once data processing by the host computer terminates, turning on the CS signal for the remote buffer causes the remote buffer to restart data transmission, picking up from the data immediately after that transmitted last. For method (b) in step (3) Transmitting a DC1 code to the remote buffer causes the remote buffer to restart data transmission.

(5) When the CNC has been reset or an alarm has been issued in the

ALARM AND RESET OF CNC

Once an alarm has been issued in the CNC, or upon the CNC being reset, the remote buffer transmits the DC3 code, then:

(1) When the CNC reset/alarm state is not to be posted to the host

(parameter No. 5003 bit 3 = 0) Turns off the ER signal, then performs close processing.

(2) When the CNC reset/alarm state is to be posted to the host

(parameter No. 5003 bit 3 = 1)

Transmits the “SYN” or “NAK” code to the host, then performs close processing.

NOTE

1 When the parameter is set to post the CNC reset/alarm

to the host, the CNC term inates comm unication upon the occurrence of an alarm in the CNC during communication in either of the following cases: (1) For foreg r ound oper ation: The reset key or the STOP

key (soft key) is pressed.

(2) For background oper ation: The STOP k ey (soft key)

is pressed. (A reset does not cause communication to terminate.)

2 When the remote buffer transmits data (for punch-out),

pressing the STOP soft key of the CNC cannot stop the data transmission until all the buff ered data between the CNC and remote buffer has been transmitted t o the host computer. To stop data transmission immediately, press the RESET key.

INTERFACE OF DATA PART

The interface of data part is in conformity the provisions of data which can be handled through the serial port by the CNC. The end of data part is judged by the detection of EOR code. Also, all data after EOR code is ignored. In general, the data part configuration is as shown below. However, in the case of DNC operation, the data already received will be lost by the CNC reset.

FUNCTION EXPLANATION

Once a single "G05;" block is specified in normal NC command format, operation can be performed by specifying desired move data and auxiliary functions in the following format. By specifying zero for all of the travel distances along all axes and the auxiliary function, the system subsequently accepts commands in normal NC command format again..

• Binary input operation on: G05;

• Binary input operation off: Zero specified for all of the travel

distances along all axes and the auxiliary function

TRANSFER RATE

After every unit time set for the appropriate parameter, the CNC extracts data of 2 * N + n bytes (where N is the number of axes, n is equal to 1 when auxiliary functions are not used and 5 when they are used.) from the remote buffer. To achieve smooth machining without any interruption of pulse distribution during machining, the baud rate of transfer between the host computer and the remote buffer must be at least

(2 * N + n) * 11/T * 1000 (bps) (where T is the unit time.).

For example, when three axes are used, auxiliary functions are not used, and the unit time is 2 msec, the baud rate must be at least

(2 × 3 + 1) bytes × 11 bits/byte/2 msec × 1000 = 38500 bps.

NOTES

NOTE

1 In binary input operation mode, any modal commands (such

as G00, G02, G03, and G90) before the G05 block are disabled, and are executed as linear interpolation G01 based on the command data format (equivalent to linear incremental commands). Upon leaving binary input operation mode, the system accepts modal commands as usual again.

2 An alarm is issued if G05; is specified in the following modes:

Cutter compensation, three-dimensional cutter compensation, interrupt macro, canned cycle, three-dimensional coordinate conversion, coordinate conversion, programmable mirror image, scaling, polar coordinate interpolation, polar coordinate command, normal direction control, hypothetical axis interpolation, cylindrical interpolation, constant surface speed control, spindle speed fluctuation detection

3 In binary input operation mode, single blocks are

disabled. By setting G5S (bit 3 of parameter No. 2007)

to 1, they are enabled. 4 Feed hold and interlocking are enabled. 5 Turning mirror images on and off is enabled even in

binary input operation. 6 Program restarts and block restarts cannot be used. 7 Registration in memory is not possible. 8 In binary input operation mode, acceleration/decelerat ion

after interpolation is subject to the acceleration

deceleration in cutting feed mode ( G01). 9 The action to be taken when manual intervention is

performed in binary input operation mode does not f ollow

ABS (bit 3 of parameter No. 2409), but the action in the

manual/absolute off state (the travel due to the

intervention is not regained at a restart) is always

assumed. In a mode other than binary input operation

mode, ABS (bit 3 of paramet er No. 2409) is effective. 10 If binary input operation is performed when acceleration

deceleration before look-ahead interpolation or fine HPCC i

enabled, acceleration/deceleration before look-ahead inter-

polation or fine HPCC remains enabled. In operation with the

unit time shorter than 8 msec, acceleration/deceler ation bef ore

look-ahead interpolation or fine HPCC must be enabled.

Only when the unit time is 1 msec (2 msec for a system

with 11 or more controlled axes), acceleration/deceleration

before look-ahead interpolation or fine HPCC can be

disabled in binary input operation mode by setting G5H (bit

3 of parameter No. 7713) to 1. Even in this case,

however, acceleration/deceleration before look-ahead

interpolation or fine HPCC must be enabled. 11 In binary input operation mode, it is not possible to

perform intervention through MDI operation.

MATERIAL FOR REMOTE BUFFER TROUBLESHOOTING

NOTE

For an explanation of the logical slot number of the R.B. (remote buffer) board, see "Determining the Logical Slot Number of the Remote Buffer Board," below.

No. External phenomenon Investigation method

1 Operation does not start even after a cycle start.

It is assumed that the following parameters are set correctly:

• Baud rate RS422: parameter 5073 RS232C: parameter 5083

• Number of stop bits RS422: parameter 5072 RS232C: parameter 5082

• Protocol type RS422: parameter 5074 RS232C: parameter 5084

• External synchronization baud rate RS422: parameter 5070

• I/O device specification number RS422: parameter 5071 RS232C: parameter 5081

2 Operation stopped prior to its completion. Follow the same procedure as that described above.

Follow the procedure described below: 1 Check if the LED indication is No. 4, described under

"Normal state" in Section 1.1. If it is not, see the "Explanation of LED Indications."

2 Perform address searches for the following addresses on

the memory display screen to check the contents of the buffer (with "long" specified for the read/write pointers and "byte" specified for the buffer). n: logical slot number of the R.B. board (Note 1) 4n810500(long) : read pointer 4n810504(long) : write pointer 4n810508(Byte)

: : buffer (8Kbyte)

4n812507(Byte)

• If the read pointer is equal to the write pointer, the buffer is empty and the cause of the error is in the remote buffer or in the host.

• If the read pointer is not equal to the write pointer, the cause of the error is in the NC.

3 Perform address searches for the following addresses on

the memory display screen to check the latest send data (256 bytes) in the remote buffer (with "long" specified for the write pointer and "byte" specified for the send buffer). 4n823100(long) : write pointer 4n823104(Byte)

: : send buffer (256byte)

4n823203(Byte) The address equal to 4n823104 + (write pointer - 1) contains the latest send data.

Note) The DRAM area of the remote buffer is 4n8000000H to

4n9FFFFFH. If an attempt is made to display an address outside this range, a system error occurs.

The causes are the same as those described above.
