The following shows the function list of the L series master/local module.
(1) List of the "basic functions"
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.
(2) List of the "functions for improving system reliability"
Disconnects a slave station that cannot continue the data link
due to a reason such as power off, so that data link can continue
among normal slave stations only.
When a slave 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 slave 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 slave
station.
Guarantees the 32-bit data of the remote register (RWr/RWw)
between programmable controller CPU and the master/local
station.
