A
SB0170 Parameter error status of each
station Stores the parameter error status of each station.
Off: All stations normal
On: Faulty station exists
When this relay is turned on, the status of each station can be checked with "Parameter error status of each
station" (SW0170 to SW0177).
Depending on the link refresh timing, the update of "Parameter error status of each station" (SW0170 to
SW0177) may be offset by one sequence scan.
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
• Reserved stations and stations higher than the maximum station No. are ignored.
SB0180 Reserved station function disable
status Stores whether there is a station whose reserved station setting is temporarily canceled.
Off: Not exist
On: Exists
When this relay is turned on, the status of each station can be checked with "Reserved station cancel setting
status" (SW0180 to SW0187).
Depending on the link refresh timing, the update of "Reserved station cancel setting status" (SW0180 to
SW0187) may be offset by one sequence scan.
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.
• When "Baton pass status of own station" (SB0047) is turned on, data prior to error is held.
SB01E1 Setting status of CC-Link IE Field
Network synchronous
communication function Stores the setting status of the CC-Link IE Field Network synchronous communication function.
Off: No setting
On: Set
SB01E9 Inter-module synchronization cycle
over flag Stores the cycle over occurrence status of the inter-module synchronization function. This relay is turned on
if output preparation processing (link scan for network modules) is not completed within the inter-module
synchronization cycle.
Off: Processing time overflow has not occurred.
On: Processing time overflow has occurred.
Once this relay is turned on, it remains turned on even if the processing is operated within the specified
inter-module synchronization cycle. The status is cleared by turning off and on the power supply or resetting
the CPU module.
