REMARKS
The following signals can also be used as I/O signals, in addition to the above.
Refer to User's Manual (Basic) for the programmable controller CPU I/O signals.
• Q series C24 ready signal (X1E) ...... Turned ON when the Q series C24 can be
• Watchdog timer error signal (X1F) ... Turned ON when the Q series C24 does not
• CH1 ERR. signal (XE) ...................... Turned ON when the CH1 ERR. has
• CH2 ERR. signal (XF) ...................... Turned ON when the CH2 ERR. has
