External Punch Start
Signal
EXWT
< G058#3 >
(Classification) Input signal
(Function) Data are output by “External I/O device control”, “Data
input/output via I/O Link – B (Master)” or “Data input/output via I/O
Link (Slave)”.
(Operation) When this signal becomes logical 1, the CNC operate as follows:
(a) Via RS-232-C or memory card slot
・Start outputting program/macro variable/parameter/ diagnosis
data/PMC data to a external I/O device or a memory card in the
mode other than MDI by background editing function.
The selection of output data depends on the data selection signal
for each data, PMC<G251#3>, EPRG<G251#4>, EVAR<G251#5>,
EPARM<G251#6> and EDGN<G251#7>.
(b) Via I/O Link on the slave side.
In case “Data input/output function via I/O Link (Slave)”: the
parameter No.8761#0=0, IOLNK<G251#0>=1, IOLS<G92#1>=0.
・Start outputting program/macro variable/parameter/ diagnosis
data (PMC) into the program storage area of the master device,
such as Power Mate i-D/H or FS16i/18i/21i etc., in the mode
other than MDI by background editing function via I/O Link
The sequence of the PMC ladder should be programmed to turn
on this signal when “External punch start signal on slave side
(EWTIO)” signal is turned on.
The selection of output data depends on the data selection signal
for each data, PMC<G251#3>, EPRG<G251#4>, EVAR<G251#5>,
EPARM<G251#6> and EDGN<G251#7>.
(c) Via I/O Link on the master side
In case “Data input/output function via I/O Link – B (Master)”:
the parameter No.8761#0=0, IOLS<G92#1>=1
・ Start outputting program or macro variable/parameter/
PMC data, which is stored in the program storage area of the
master device, to the slave device in the mode other than
MDI by to background editing function via I/O Link
