5.3 Write sequence for message transmitting

5.3.1Flag control timing

In case of transmitting a message, the following flags are used for handshaking between T3 and AS311. These flags are the bits of the I/O registers assigned to the AS311. Refer to section 4.1.

Write ready

Bit F of XW(n) for channel 1 or XW(n+1) for channel 2

Transmit complete

Bit E of XW(n) for channel 1 or XW(n+1) for channel 2

Transmit error

Bit D of XW(n) for channel 1 or XW(n+1) for channel 2

Transmit start

Bit F of YW(n+2) for channel 1 or YW(n+3) for channel 2

The message transmitting procedure is as follows. It is called “write sequence for message transmitting”.

T3 checks Write ready is ON

T3 writes a message into buffer memory (transmitting data area) by WRITE instruction

T3 sets Transmit start to ON

AS311 resets Write ready to OFF

Normal transmitting

Transmitting error

AS311 sends out the message and

sets Transmit complete to ON

T3 resets Transmit start to OFF

AS311 resets Transmit complete to OFF, and sets Write ready to ON

AS311 sets the error information into buffer memory (parameter area) and sets Transmit error to ON

T3 reads the error information from buffer memory (parameter area) by READ instruction, and resets Transmit start to OFF

AS311 resets Transmit error to OFF,

and sets Write ready to ON
