13. INPUT/OUTPUT OF DATA
B–63523EN–1/03
1660
[Valid data range] 0 to 3, 5, 10
These parameters are valid only when bit 0 (IO4) of parameter No. 110 is
set to control the I/O channels separately.
The parameters set individual input/output devices if the I/O channels are
divided into these four types: input and output in the foreground and input
and output in the background. The input device in the foreground is set in
parameter No. 20. For the details of the settings, see the table provided
with the description of parameter No. 20.
NOTE
If different input/output devices are simultaneously used in
the foreground and background, just a value from 0 to 3 can
be specified for the background device.
If an attempt is made to use a busy input/output device, an
alarm (P/S233 or BP/S233) will be raised. Note that the
settings 0 and 1 indicate the same input/output device.
