Description
Performs on/off data communication with remote I/O stations.
Performs on/off data and numeric data communication with remote
device stations.
Performs on/off data and numeric data communication with local
stations.
Performs communication with intelligent device station, by cyclic
transmission, and transient transmissions.
Description
Disconnects a device station that cannot continue the data link due to
a reason such as power off, so that data link can continue among
normal device stations only.
When a device station, which has been disconnected from the
network due to a reason such as power off, returns to the normal
status, it automatically joins the data link.
Sets whether to stop or continue the data link when an error that
stops the operation occurs at the master station programmable
controller CPU in the system that has no standby master station.
When "Continue" is set, the diagnostics of the master station can be
performed from local stations.
Sets whether to clear or hold the input data (remote input RX) from a
station that detected a data link error due to a reason such as power
off.
Sets whether to refresh or forcibly clear output data (remote output
RY) to the device stations when the programmable controller CPU
comes to STOP.
When "Clears Compulsorily" is set, the remote output RY turns off
when the operation stops due to STOP of programmable controller
CPU or due to an error occurrence.
Continues the data link by switching the control to the standby master
station when a problem occurs in the master station.
Starts data link when either of the master or standby master station is
turned on.
Guarantees the consistency of the cyclic data for each device station. Page 159, Section 8.2.9
Guarantees the 32-bit data of the remote register (RWr/RWw)
between programmable controller CPU and the master/local station.
