External Read Start
Signal
EXRD
< G058#1 >
(Classification) Input signal
(Function) Data are input 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 registration/collation of program or input of macro variable/
parameter/PMC data from a external I/O device or a memory
card in the mode other than MDI by background editing function.
The selection of input 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 registration/collation of program or input of macro variable/
parameter/PMC data from 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 read start signal on slave side
(ERDIO)” signal is turned on.
The selection of input 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>.
