3.3 DUAL ASSIGNMENT OF I/O LINK CHANNEL
Alter the NOTE of "3.1WHAT IS THE I/O LINK?"
3.4 ABOUT THE I/O LINK
NOTE
1 To use channels 2 to 4 of the I/O Link, the I/O Link
expansion option is required for each channel.
2 The transfer cycle of signals from I/O devices is 2 ms
with channels 1 and 2, or 4 or 8 ms (execution cycle
of the first ladder level) with channels 3 and 4. For
this reason, when X signals(Skip signal,
Deceleration signal for reference position return,
Interlock signal for each axis, Emergency stop
signal, etc.) that are directly referenced by the CNC
are assigned to channels 3 and 4, delay of the input
signal may be problem. In this case, assign these X
signals to channels 1 and 2. Refer to "Series
30i/31i/32i-A CONNECTION MANUAL
(FUNCTION) (B-63943EN-1)" about detail of these
X signals.
3 The transfer cycle of signals from I/O devices is 4 or
8msec with channels 3 and 4. Therefore there may
be 4 or 8msec delays between the signals located in
different byte.
Add new section "3.3 SETTING I/O ADDRESS FOR I/O LINK CHANNEL" after "3.2 ASSIGNMENT
METHOD"
3.5 SETTING I/O ADDRESS FOR I/O LINK CHANNEL
3.5.1 Outline
Interface between PMC and external I/O devices consists of I/O address
of 128 bytes of X/Y0 to X/Y127, X/Y200 to X/Y327, X/Y400 to X/Y527,
and X/Y600 to X/Y727 as shown below.
