Description
Shows each station network No. matching status.
• 0: All station network No. match
• 1: One or more station with network No. mismatch.
When a station with a mismatched network number is present, the status of each station can be
confirmed using 'Network No. matching status' (SW00F8 to SW00FF).
The local station stores the moderate and major error occurrence status of the CPU module of each
station.
Remote I/O stations, remote device stations, and intelligent device stations store the moderate/major
error occurrence status of each station.
• OFF: No stations with moderate or major errors
• ON: One or more stations with a moderate or major error
If there are stations generating moderate or major errors, the status of each station can be confirmed
using 'each station CPU moderate or major error occurrence status' (SW0100 to SW0107).
<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 moderate and major error occurrence status of the MELIPC of the master station (master operating
station) is stored.
• OFF: No moderate or major error
• ON: Moderate or major error
<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 each station number duplication occurrence status.
• 0: No duplication in any station numbers
• 1: Stations with duplicate station numbers
When a station with an overlapping station number is present, the status of each station can be
confirmed using 'Station number duplication occurrence status' (SW0108 to W010F).
The moderate and major error occurrence status of the CPU module of station number 0 is stored.
• OFF: No moderate or major error
• ON: Moderate or major error
<Conditions>
Enabled when sub-master function is used
The local station stores each station CPU module minor error occurrence status.
Remote I/O station, remote device station, and intelligent device station stores the minor error
occurrence status of each station.
• OFF: All stations normal, or one or more moderate or major error stations
• ON: One or more minor error stations
If there are stations generating a minor error, the status of each station can be confirmed in 'each station
CPU minor error occurrence status' (SW0110 to SW0117).
<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 minor error occurrence status of the MELIPC of the master station (master operating station) is
stored.
• OFF: No minor error, or moderate or major errors occurring
• ON: Minor error
<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 currently occurring at port 2 of each
station.
• 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, circuit status caution level is occurring, the status of each station can be
confirmed with 'each station port 2 error frame reception current status (1)' (SW0130 to SW0137).
<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 current error frame reception status.
• OFF: No reception
• ON: Receiving
<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.
