Details of I/O signals

Module failure (X0)
This signal is used to check the status of the RJ71GN11-T2.
• Off: Module normal
• On: Module failure
Module failure (X0)
Module READY (XF)
Power-on
Own station data link status (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 stations data link status (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).
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 240 Module failure (X0))
