Detailed Description of the Module I/O Signals for the Programmable Controller CPU
3 – 10 MITSUBISHI ELECTRIC
EMCY message available (X(n+1)1), EMCY message area clear request (Y(n+1)1)
●
If there is at least one CANopen emergency received (reception of an Emergency message from
at least one activated EMCY consumer objects), the EMCY message available (X(n+1)1) will turn
ON.
●
To clear all EMCY messages, turn ON the EMCY message area clear request (Y(n+1)1). All EMCY
messages will be then cleared and the EMCY message available (X(n+1)1) will be turned OFF.
●
If a new EMCY message is received while the EMCY message area clear request (Y(n+1)1) is ON,
this will be cleared automatically.
●
After the EMCY message area clear request (Y(n+1)1) is turned OFF, the ME3CAN1-L will store the
newly received EMCY messages again.
For more error details, please refer to the sections 4.6.12 and 3.5.17.
Time stamp setting completed (X(n+1)2), Time stamp set request (Y(n+1)2)
After setting the necessary time stamp information in Un\G50 to Un\G58, please turn ON the time
stamp set request (Y(n+1)2).
After the setting is finished, the time stamp setting completed signal (X(n+1)2) will be turned ON, and
the request signal can be turned OFF. When the ME3CAN1-L is the current network master and Pro-
ducer, then the first time stamp will be sent.
Time stamp information is available in buffer memory (X(n+1)3), Time stamp read request
(Y(n+1)3)
To read the time stamp, please set the time stamp read request (Y(n+1)3) to ON.
The time stamp information will be stored in the buffer memory addresses Un\G50 to Un\G58 and the
time stamp information is available in buffer memory (X(n+1)3) signal will be turned ON to indicate
that actual time stamp information is available.
Command 1 execution completed (X(n+1)7, Command 1 execution request (Y(n+1)7)
●
These signals are used for execution of Command Interface 1.
●
After writing the necessary command parameter (refer to section 3.5.18), turn ON Y(n+1)7 to
execute the command. If the command execution is finished, X(n+1)7 will be turned ON.
