Description
Shows if a reception frame error of the circuit status warning level is currently occurring at port 2 of each
station.
• 0: A reception frame error of the circuit status warning level is not occurring at port 2 of any station.
• 1: A reception frame error of the circuit status warning level is occurring at port 2 of at least one
station.
If a reception frame error of the circuit status warning level is occurring, the status of each station can be
confirmed with 'each station port 2 error frame reception current status (2)' (SW0138 to SW013F).
<Conditions>
• Enabled when 'baton pass status' of own station (SB0047) is OFF.
• When 'baton pass status of own station' (SB0047) is ON (error), the data immediately before is
retained.
Shows if a reception frame error of the circuit status caution level is occurring at port 2 of each station
from when the power supply is turned ON.
• 0: A reception frame error of the circuit status caution level is not occurring at port 2 of any station.
• 1: A reception frame error of the circuit status caution level is occurring at port 2 of at least one
station.
If a reception frame error of the circuit status caution level occurred, the status of each station can be
confirmed with 'Port 2 error frame reception detection status (1)' (SW0150 to SW0157).
<Conditions>
Enabled when 'baton pass status of own station' (SB0047) is OFF. When 'baton pass status of own
station' (SB0047) is ON (error), the data immediately before is retained.
Stores the master station (master operating station) port 2 error frame reception status from power ON
to present.
• OFF: Not receiving
• ON: One or more receptions
<Conditions>
Enabled when 'baton pass status of own station' (SB0047) is OFF. When 'baton pass status of own
station' (SB0047) is ON (error), the data immediately before is retained.
Shows if a reception frame error of the circuit status warning level is occurring at port 2 of each station
from when the power supply is turned ON.
• 0: A reception frame error of the circuit status warning level is not occurring at port 2 of any station.
• 1: A reception frame error of the circuit status warning level is occurring at port 2 of at least one
station.
If a reception frame error of the circuit status warning level occurred, the status of each station can be
confirmed with 'Port 2 error frame reception detection status (2)' (SW0158 to SW015F).
<Conditions>
• Enabled when 'baton pass status' of own station (SB0047) is OFF.
• When 'baton pass status of own station' (SB0047) is ON (error), the data immediately before is
retained.
Stores each station parameter error status.
• OFF: No error in any station
• ON: Error station found
In the event of faulty stations, the status of each station can be confirmed with 'each station parameter
error status' (SW0170 to SW0177).
<Conditions>
• Enabled when 'baton pass status of own station' (SB0047) is OFF. When 'baton pass status of own
station' (SB0047) is ON (error), the data immediately before is retained.
• The status is not stored for the reserved stations and the station numbers after the maximum station
number.
Stores presence of reserved stations that have had a temporary clear.
• OFF: Not present
• ON: Present
In the event of these stations, the status of each station can be confirmed with 'reserved station
temporary clear status settings status' (SW0180 to SW0187).
<Conditions>
Enabled when 'baton pass status of own station' (SB0047) is OFF. When 'baton pass status of own
station' (SB0047) is ON (error), the data immediately before is retained.
Stores CC-Link IE Field Network synchronous communication function settings status.
• OFF: No settings
• ON: Set
Stores cycle exceeded status of the synchronous communication cycle. If output preparation processing
(in the case of network modules, link scan) does not complete within the synchronous communication
cycle, this is ON. An ON state is maintained even after the program is later completed within the
specified fixed scan communication cycle. Clear by turning the power OFF to ON or clearing the reset
state.
• OFF: Processing time not exceeded
• ON: Processing time was exceeded
