■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.
■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.

Error code
An error code is stored into RWr1 when a moderate error or major error occurs.
Turning on Error clear request flag (RWw0.b10) after eliminating the cause of the error clears the error code.
Errors that occurred in the past can be checked with Error history data  (address: 0A00H to 0AEFH). For error history, refer
