Details of the input signal

The following shows the on/off timing or condition of the input signal.
Module READY: X0
When the CPU module is reset or powered on, this signal turns on as soon as the RJ51AW12AL is completely ready to be
processed.
DP/DN short error: X1
This signal turns on when a short circuit occurs in the transmission cables (DP, DN) or the maximum supply current is
exceeded.
■Turning off of 'DP/DN short error' (X1)
After removing the short circuit in the transmission cables (DP, DN) or adjusting the current within the specification range,
perform either of the following operations. Until then, 'DP/DN short error' (X1) remains on.
• Reset the CPU module or power off and on the system.
• Turn on and off 'Error flag clear command' (Y0).
For how to remove the short circuit in the transmission cables (DP, DN) or adjust the current within the specification range,
refer to the following.

24V/DP short error: X2
This signal turns on when any of the transmission cables (24V, DP) is short-circuited.
■Turning off of '24V/DP short error' (X2)
After removing the short circuit in the transmission cables (24V, DP), perform either of the following operations. Until then,
'24V/DP short error' (X2) remains on.
• Reset the CPU module or turn off and on the power.
• Turn on and off 'Error flag clear command' (Y0).
For how to remove the short circuit in the transmission cables (24V, DP), refer to the following.

Transmission cable voltage drop error: X3
This signal turns on when the 24VDC external power supply voltage drops.
■Turning off of 'Transmission cable voltage drop error' (X3)
After removing the drop of the 24VDC external power supply voltage, perform either of the following operations. Until then,
'Transmission cable voltage drop error' (X3) remains on.
• Reset the CPU module or power off and on the system.
• Turn on and off 'Error flag clear command' (Y0).
For how to remove the drop of the 24VDC external power supply voltage, refer to the following.

DP/DN disconnection error: X4
This signal turns on when the transmission cables (DP, DN) or a slave module is disconnected.
■Turning off of 'DP/DN disconnection error' (X4)
After removing the short circuit in the transmission cables (DP, DN) or reconnecting the slave module, perform either of the
following operations. Until then, 'DP/DN disconnection error' (X4) remains on.
• Reset the CPU module or power off and on the system.
• Turn on and off 'Error flag clear command' (Y0).
For how to remove the short circuit in the transmission cables (DP, DN) or reconnect the slave module, refer to the following.
