●
When multiple errors occur, only the latest error code is stored in CH  Latest error code (RWr22, RWr3A) or CH  Latest
warning code (RWr23, RWr3B). (Error codes which do not have  on their names are stored in CH1.)
Old errors can be checked with the error history of GX Works2.
For the error history, refer to the following.
• Checking by executing a command of the slave station ( Page 205, Section 11.1 (1))
• Error history 1 to 15 (address: 0A00
H
to 0AEF
H
) ( Page 276, Appendix 3 (14))
● Turning on CH  Error reset command (RY36, RY4E) resets errors. However, the error causes are detected again and
thus the error codes are stored again unless the error causes are removed.
