(e) Remote READY (RWr0.b11)
This signal is used as an interlock condition when the master station reads/writes data from/to the remote
register or remote buffer memory areas of the I/O module.
With Initial operation setting (address: 0004H) being set to With initial processing (0), Remote READY
(RWr0.b11) turns on when initial processing is completed after powering on of the module.
With Initial operation setting (address: 0004H) being set to Without initial processing (1), Remote READY
(RWr0.b11) turns on after powering on of the module.
When Error status flag (RWr0.b10) turns on, Remote READY (RWr0.b11) turns off.
(f) Warning status flag (RWr0.b12)
Warning status flag (RWr0.b12) turns on when a minor error occurs.
Five seconds after the cause of the minor error is eliminated, the value in Warning code (RWr2) is cleared
automatically (0000H is stored) and Warning status flag (RWr0.b12) turns off.

Errors that occurred in the past can be checked with Error history data  (address: 0A00H to 0AEFH). For error
history, refer to the following.
• Error history data  (address: 0A00H to 0AEFH) ( Page 278, Appendix 3 (15))
(3) Warning code (RWr2)
The error code is stored when a minor error occurs.
Five seconds after the cause of the minor error is eliminated, the error code is automatically cleared.
