*1 If the station is communicating in multicast mode, this item is enabled when 'Data link error status of own station' (SB0049) is off.
Description
Stores the moderate/major error occurrence status of the CPU module on the
master station.
Off: No moderate/major error
On: Moderate/major error
Stores the minor error occurrence status of each station.
When the target station is RJ71GN11-EIP, the occurrence status on the CPU
module is stored.
Off: All stations normal or station with a moderate/major error exists
On: Station with a minor error exists
When this relay is turned on, the status of each station can be checked with
'CPU minor error status of each station' (SW0110 to SW0117).
Depending on the link refresh timing, the update of 'CPU minor error status of
each station' (SW0110 to SW0117) may be offset by one sequence scan.
Since a local station cannot obtain the station information of the CC-Link IE
TSN Class A remote station when communicating in multicast mode, "0:
Normal, or a moderate or serious error occurring" is reflected to the CC-Link
IE TSN Class A remote station.
Stores the minor error status of the CPU module on the master station.
Off: No minor error or a moderate/major error
On: Minor error
Stores the setting status of the CC-Link IE TSN Network synchronous
communication function.
Off: No setting
On: Set
Stores the cycle over occurrence status of the inter-module synchronization.
This relay is turned on if output preparation processing (cyclic data transfer
processing for network modules) is not completed within the inter-module
synchronization cycle. After that, it remains turned on even if the processing
is operated within the specified inter-module synchronization cycle. The
status is cleared by powering off and on the system or by resetting the CPU
module.
Off: Processing time overflow has not occurred.
On: Processing time overflow has occurred.
