GENERAL DESCRIPTION

Computer communication function for YASNAC i Series provides wide-ranging communication with a host computer by adding a communication module to the CPU unit.

Since this module is equipped with a microprocessor for the purpose of communication, it can perform communication between the host computer and the NC at high speed by minimizing the effect on the motion control that is a basic performance of the NC.

It principally has the following functions.

Computer Operation

(1)

Controls NC from host computer.

DNC Operation

(2)

Performs continuous machining by NC program from host computer.

DNC High Speed Cutting Function

(3)

Performs cutting operation for extended time by using cutting data from host computer.

SD :

Sending data (output)

Receiving data (input)

RD :

RS :

Request sending (output)

This signal turns ON when starting to send out in case of transmitting the data from this module. Note : It functions as a request receiving signal in Protocol 1.

Refer to item 3. PROTOCOL 1 for further details.

Cs :

Capable of sending (input) The data can be send out from this module when this input signal is ON.

SG :

Signal grounding

—4–

ER : Data terminal ready (output)

When this signal turns ON, it shows the communication module is ready for operation.

If it is OFF, process the error with host computer.

DR : Data set ready (input)

When this signal turns ON, it shows that the host computer is ready for operation. If it is OFF, this module processes the error.

Note : In RS-422, * SD, * RD, * RS, * CS, * ER and * DR signals are also provided in

addition to the above signals. These signals are the reverse of the signals explained above.

Due to difference between RS-232C and RS-422 actual signal level becomes as shown in

Table 2.2.

3. PROTOCOL 1

3.1 Outline of Protocol 1

This is Protocol 1 prepared for DNC operation by the NC part program transferred from the host computer and other external equipment. For this purpose, it uses the transmission control signal “RS (request sending)” through the serial transmission line of communication module (optional) for NC unit.

3.5 Precautions

The receiving data is disregarded until initial “%” code (or “EOB” code) is received.

(1)

The part programs stored in buffer memory to start DNC operation can be made for 128/

(2)

256/512 bytes by setting NC parameter. (Refer to item 7. NC SE~lNGS/PARAMETERS FOR COMMUNICATION MODULE.)

If NC part program is not received for longer than 3sec. even if turning ON request sending

(3)

signal during NC part program receiving mode, it is regarded as the end of the NC part program and processed in the same manner as “%” code receiving.

(4)

If DNC operation is interrupted by alarm issue (at communication module or NC control unit) or by NC reset input ON during DNC operation, RS signal (request sending) turns OFF.

Transmission sequence is the same as reading DC1 to RS ON and DC3 to RS OFF,

(5)

respectively, in par. 4.5 “Description on Transmission Sequence. ” Nevertheless, “.SYN”

or “NAK” is not output.

When DR (data set ready) signal is not used, or when DR signal is turned off to use during

(6)

communication, set the pmO030 D5 parameter “DR signal checked/not checked” to “DR signal not checked. ”
