EMCY message available (X11), EMCY message area clear request (Y11)
When the RJ71CN91 receives an EMCY message from another node, 'EMCY message available' (X11) turns on.
The received EMCY message can be checked in 'EMCY message buffer' (Un\G750 to Un\G859). ( Page 170 EMCY
message buffer (Un\G750 to Un\G859))
To clear all received EMCY messages, turn on 'EMCY message area clear request' (Y11). All EMCY messages will be then
cleared and 'EMCY message available' (X11) will turn off.
While 'EMCY message area clear request' (Y11) is turned on, EMCY messages are not received and 'EMCY message
available' (X11) will not turn on.
When 'EMCY message area clear request' (Y11) is turned off, the reception of EMCY messages resumes.
For details on EMCY messages, refer to the following.

To read the Time stamp, turn on 'Time stamp read request' (Y13).
The Time stamp will be stored in 'Time stamp' (Un\G50 to G59), and 'Time stamp information available in buffer memory'
(X13) will be turned on.
After 'Time stamp information available in buffer memory' (X13) is turned on, turn off 'Time stamp read request' (Y13). Then,
'Time stamp information available in buffer memory' (X13) will be turned off.
The Time stamp when 'Time stamp information available in buffer memory' (X13) is turned on will be stored in
