The DI/DO signal timing charts applicable when data input/output
function B based on the I/O Link is used are shown below. When the
ordinary data input/output function based on the I/O Link is used, 1)
through 4) in the figures are subject to MDI–based input/output.
(1) When ordinary input/output is performed
1) Specify a program number with the PMC function
instruction (WINDW).
2) Specify the group number of the power mate CNC to be
used for input/output with group number specification
signals SRLNI0 to SRLNI3.
3) Set I/O Link specification signal IOLS to 1.
4) For input, set external read start signal EXRD to 1.
For output, set external punch start signal EXWT to 1.
5) Processing by the Series 0i/0i Mate outputs slave I/O Link
selection signal IOLNK and group number output signals
SRLNO0 to SRLNO3.
6) Using a ladder program, make the necessary preparations
for data input/output using the I/O Link.
7) Upon the completion of step 6), set the I/O Link
confirmation signal IOLACK to 1. The Series 0i/0i Mate
waits until IOLACK is set to 1.
8) The Series 0i/0i Mate outputs slave external read/write
signal ERDIO/EWTIO, and slave input/output data
selection signals EPRG, EVAR, EPARM, and EDGN.
9) The Series 0i/0i Mate waits for the external I/O device
control function of the power mate CNC to start. (The
Series 0i/0i Mate waits for the external I/O device control
function of the power mate CNC to start.)
10) The Series 0i/0i Mate performs data input/output through
the I/O Link.
11) Upon the completion of data input/output, the Series 0i/0i
Mate sets the slave external read/write start signal and slave
input/output data selection signals to 0.
12) The Series 0i/0i Mate waits for the completion of the
external I/O device control function of the power mate
CNC. The Series 0i/0i Mate waits for termination or
completion of the external I/O device control function of
the power mate CNC.
13) Upon the completion of the operation of the external I/O
device control function of the power mate CNC, the Power
Mate read/write in–progress signal BGION is set to 0.
14) The Series 0i/0i Mate sets the slave I/O Link selection
signal IOLNK to 0.
15) I/O Link specification signal IOLS and I/O Link
confirmation signal IOLACK are set to 0.
