Details of input signals

Module failure (X0)
This signal is used to check the status of the CC-Link IE TSN Plus module.
• Off: Module normal
• On: Module failure
Module failure (X0)
Module READY (XF)
Power-on
Own Data Link (X1)
This signal is used to check the data link status of the own station.
• Off: Data link stop
• On: Data link in progress
'Data link error status of own station' (SB0049) has the same signal, but when using it in a program, use either X1 or 'Data link
error status of own station' (SB0049) only. Also note that the on/off conditions for X1 and SB0049 are reversed.
If an error occurs, the cause of the fault can be checked by CC-Link IE TSN/CC-Link IE Field diagnostics or 'Cause of data
link stop' (SW0049).
Other Data Link (X3)
This signal is used to check the data link status of other stations.
• Off: All stations normal
• On: Faulty station exists
'Data link error status of each station' (SB00B0) has the same signal, but when using it in a program, use either X3 or 'Data
link error status of each station' (SB00B0) only.
If an error occurs, the faulty station can be checked by CC-Link IE TSN/CC-Link IE Field diagnostics or with 'Data link status
of each station' (SW00B0 to SW00B7).
Own error (XE)
This signal turns on or off depending on the occurrence status of the own station error.
• On: An error (minor error, moderate error, or major error) has occurred.
• Off: No error has occurred.
Module READY (XF)
This signal is used to check the status of module operation preparation.
• Off: Not available for module operation
• On: Available for module operation
For the module READY timing chart, refer to Module failure (X0). ( Page 453 Module failure (X0))
