Setting method
■Setting of the Input Data from Data Link Faulty Station
Select the input data setting under "Supplementary Cyclic Settings" in "Application Settings." (Page 71 Supplementary
cyclic settings)
■Data Link Setting at CPU Failure
Select the data link setting under "Supplementary Cyclic Settings" in "Application Settings." (Page 71 Supplementary
cyclic settings)
Status difference between a master station and a slave station at an error
The station status at an error varies depending on the combination of "Input Data from Data Link Faulty Station", "Output
Mode upon CPU STOP", "Data Link Setting at CPU Failure," and "Output Mode Setting at CPU Error" under "Supplementary
Cyclic Settings" in "Application Settings." When configuring the settings, consider the station status at errors listed below.
■Status of a master station (when operating as a master station) and remote I/O station
Data link status
When the CPU "Output Mode
module of the Setting upon
master station is set CPU Error"
to STOP at an error (setting in the
("Data Link Setting master station)
at CPU Failure" =
"Continue the Data
Link")
When the CPU "Output Data
module of the Setting during
master station is set CPU STOP"
to STOP (setting in the
master station)
When data link for "Input Data
the entire system is Setting from
stopped Data Link
Faulty Station"
(setting in the
master station)
When a "Input Data
communication Setting from
failure (such as Data Link
power off) occurs in Faulty Station"
a remote I/O station (setting in the
master station)
When a "Input Data
communication Setting from
failure (such as Data Link
power off) occurs in Faulty Station"
a remote device (setting in the
station master station)
When a "Input Data
communication Setting from
failure (such as Data Link
power off) occurs in Faulty Station"
an intelligent device (setting in the
station master station)
*1 The target data is cleared to transmit 0 data to the slave station, but the value of the target data storage destination buffer memory in the
master station is retained. When an non-latch device (including Y devices) is set as a refresh device, also clears the target data storage
buffer memory in the master station.
*2 Clears when a non-latch device (including Y devices) is set as a refresh device. When setting the latch device or without link refresh
setting, holds or clears according to "Output Data Setting at CPU STOP."
