Specifications
AJ61BT11/A1SJ61BT11
The communication of ON/OFF information with remote I/O
station is performed.
The communication of ON/OFF information and numerical data
with remote device station is performed.
The communication of ON/OFF information and numerical data
with local station is performed.
The communication is performed with intelligent device station
using cyclic transmission and transient transmission.
By setting remote station and local station, which are to be
connected in the future, as reserved stations, these stations are
not treated as data link faulty stations.
If a connected module is specified, no data link is available.
Remote station and local station that cannot perform data link
due to the power supply off, etc. will not be treated as data link
faulty stations with this function.
The data link status when operation continuation error occurs on
the master station programmable controller CPU can be set.
Parameter writing is not
required at each startup of
master module by registering
2
parameters to E PROM of
master module.
The input (received) data status (cleared/hold) from the station
that has data link error caused by the power supply off, etc. can
be set.
Resetting can be performed by
the sequence program without
resetting programmable
controller CPU in the case the
switch setting is changed or an
error has occurred in a module.
The stop and restart of data link is available during the data link
execution.
The module disconnected from data link by the power supply off,
etc. can automatically return to data link, when restored to the
normal status.
The module that cannot perform data link due to the power
supply off, etc. is disconnected and data link is kept with normal
modules only.
Data link status can be checked.
This check can be used for the interlock etc. of sequence
program.

When the switch setting is
changed, turn the power
supply of programmable
controller system OFF 
ON or reset the
programmable controller
CPU.
