Message Transmit Trigger Flags (Un\G8400-Un\G8402) - Mitsubishi Electric MELSEC L-Series User Manual

Buffer Memory Details: Layer 2 Message Mode
3.6.4 Message transmit trigger flags (Un\G8400–Un\G8402)
The transmission of a message in Layer 2 mode can be triggered via the following flags. Transmit
requests on receive message slots are discarded (refer to section 3.6.2 for details on configuring mes-
sage slots).
After setting these flags, turn on Message transmit trigger request (Yn4) to start triggering the mes-
sage transmission.
If a bit is set to ON, the corresponding transmit message will be sent as soon as a transmit buffer is
available.
The flags are reset automatically as soon as the message is written into the transmit buffer. Message
transmit trigger completed (Xn4) will turn ON if all the messages are written into the transmit buffer.
Please refer also to section 3.3.1.
