As the signal for starting external workpiece number search:

The automatic operation start signal ST is used. When automatic operation (memory
operation) is started, a search is made.

The external workpiece number search start signal EPNS is used. ST does not start a
search.

Correspondence between workpiece numbers and program numbers in external workpiece number

search (PN)

[Input type] Parameter input

[Data type] 2-word path

[Valid data range] -1 to 99

This parameter has the following meaning according to the value set.
-

When a value from 0 to 99 is set

(Program number) = (setting)*100+(workpiece number)

This means that the setting specifies the higher 2 digits of a program number.

When the value -1 is set

The higher 2 digits of a program number represent the minimum of the existing
program numbers.

Example

When workpiece number 21 is specified, program numbers such as O0021, O0121,
and O0221 are searched for. If O0021 is not found, but O0121 and O0221 are found,
O0121 is selected as the program number.

NOTE

This parameter is valid when a workpiece number is specified using
the PN1 to PN16 signals (when bit 1 (EPN) of parameter No. 3006
is set to 0).

EXTERNAL KEY INPUT

Overview

MDI key codes can be sent from the PMC to CNC by means of interface signals. This allows the CNC to
be controlled in the same way as when the operator performs MDI key operation.

Signal

Signal list

Control is realized by exchanging the following interface signals (Table 16.6 (a)) between the PMC and
CNC:

Signal detail

The processing flow in the PMC is shown Fig. 16.6 (a).

< EKSET = EKENB >

Invert EKSET

< Has key input ended? >

< INHKY = “0” >

< EKSET = EKENB >

Set ENBKY = “0”

(END)

1) Set the external key input control

Set ENBKY = “1”

2) Check whether a key code can be set.

3) When a key code can be set:

(1) Set the key code to be input.

(2) Invert the EKSET signal to instruct the CNC to read

the key code.

4) Repeat the operation for the key data to be input

5) After reporting the last data, check that the CNC

has read the key data.

6) Release external key input control mode.

Fig. 16.6 (a)

NOTE

Read processing is controlled by exclusive-ORing (XOR) the key code read
signal (EKSET) with the read completion signal (EKENB). When the EKSET and
EKENB signals differ in their logic, the CNC reads the input key code. Once
reading has been completed, the CNC inverts the EKENB signal to match its
logic with that of the EKSET signal.

In the PMC, on the other hand, a new key code cannot be set while the EKSET
and EKENB signals differ in their logic.

External key input mode selection signal ENBKY<G066.1>

[Classification] Input signal

[Function] While this signal is turned on “1”, external key input control is enabled. In external key

input control mode, any MDI key operations are ignored.

NOTE

1 When ENBKY is set to “1” to enable external key input control, key

code input based on the C Language Executor is also ignored.

2 Key codes input with the external key input function can be read by

the macro executor and C Language Executor.

NOTE

3 Even when external key input control is enabled, pressing the

key on the MDI keyboard

for 5 seconds can produce a hard copy of the screen.

Pressing the

key while a hard copy of the screen is being

produced can cancel the production of a hard copy of the screen.

Even if the key code of the

key is input with the external key

input function, the production of a hard copy of the screen cannot
be stopped.

Key code read signal EKSET<G066.7>

[Classification] Input signal

[Function] This signal instructs the CNC to read the input key code.

If the logical state of this signal is opposite to the logical sate of the key code read
completion signal EKENB, a key code read is specified.

Key code signals EKC0 to EKC7<G098>

[Classification] Input signal

[Function] These signals set an input key code.

Key input disable signal INHKY<F053.0>

[Classification] Output signal

[Function] While this signal is “1”, no key code is accepted in external key input control mode.

[Output cond.] This signal is set to “1” during program editing or program input/output.

Program screen display mode signal PRGDPL<F053.1>

[Classification] Output signal

[Function] This signal posts whether the CNC is displaying the program screen.

[Output cond.] This signal is set to “1” when the program screen is displayed.

Key code read completion signal EKENB<F053.7>

[Classification] Output signal

[Function] This signal reports that the CNC has read a key code.

[Output cond.] When the CNC completes key code read operation, the logical state of this signal is set to

the same state as for the key code read signal EKSET.

16.7

ONE TOUCH MACRO CALL

Overview

This function enables the following three operations in pushing the switch installed in the machine only
by the change in a minimum LADDER program.

(1)  Changes to MEM mode.
(2)  Execution of macro program registered in memory.
(3)  Return to the mode before macro program is executed.

And the program which had been selected before macro program is executed is automatically
selected.

This function is enabled only in the reset status (not during a reset). That is, this function cannot be used
during automatic operation (including stopping and suspending of automatic operation), a reset, or an
emergency stop.

Explanation

Sequence between PMC and CNC

The signal must be processed between PMC and CNC according to the following procedures.

Start

(1) The macro call start signal MCSTx <Gn512.0 to Gn513.7> is input from PMC to CNC based on the

signal from the macro call switch installed in the machine.

Mode change

(2) CNC outputs the mode notification signal and the mode change request signal MCRQ <Fn512.1>

when the macro call start signal (MCSTx) is detected. At this time, MEM mode is notified as the
mode notification signal. The macro call executing signal MCEXE <Fn512.0> and Call program
confirmation signal MCEXx <Fn514.0 toFn515.7> are output at the same time.

(3) PMC must change the mode based on the signal output in the step of above (2).
(4) Set “1” in the mode change completion signal MCFIN <Gn514.0> by PMC when the mode change

is completed. If this mode is different from that specified from the CNC in (2) or the reset mode, an
alarm PS5306 occurs.

Execution of macro program

(5) When MCFIN signal is set to “1”, CNC executes the macro program.

End of macro program

(6) Instruct M02 or M30 at the end of the macro program.

Moreover, input external reset signal (ERS) or reset&rewind signal (RRW) with M02 or M30 on the
PMC side.
Upon completion of the reset, the program selected before execution of the macro is automatically
selected.  The mode change request signal(MCRQ) and mode notification signals are output at the
same time. At this time, the mode when macro call start signal (MCSTx) is input is notified as the
mode notification signal.

Return of mode

(7) Change the mode on the PMC side based on the signal output in the step of above (6).
(8) Set “1” in Mode change completion signal (MCFIN) on the PMC side when the mode change is

completed. On the CNC side, the Mode change request signal (MCRQ), the Macro call executing
signal (MCEXE) and the Call program confirmation signal(MCEXx) are set to “0” concurrently with
asserting of the Mode change completion signal (MCFIN). The PS5306 alarm is not checked at this
time.
