■Buffer memory setting error display (Un\G39)
This area stores the buffer memory address where an error occurs when a value out of the setting range is written to the
buffer memory and 'Error status' (Un\G29.6) turns on. If multiple errors occur, the buffer memory address where the first error
occurs is stored.
To reset this area, turn on 'RJ71CN91 error clear request' (YF).
■Command interface (CIF) (Un\G1000 to Un\G1066)
This area is used to access the object dictionary of a local node or network node. Access using commands are for SDO read/
write and EMCY message communication. For how to run a command, refer to the following.
