Process output toggle
The PLC has to set the TI bit to 0. After the handshake, the PLC has to set the TI bit to 0 again.
The BVS ID sets the TO bit to 0 at the end of the handshake.
The PLC sets command ID, data length and the first part of the data in the output buffer. The data length
is the length of the entire data to be transferred. Afterwards, the PLC sets the
Job bit.
BVS ID reads the strobe bit and then command ID, data length and (partial) data.
BVS ID accepts the command, sets the Job Start bit, and executes it and sets command status, data
length and (partial) data in the input buffer and then the Job End bit.
The PLC reads the Job End bit and then command status, data length and (partial) data. Based on the
data length and size of the cyclical buffer, the PLC recognizes that additional data still have to be
transferred.
The PLC inverts the
TI bit and waits for the inverted TO bit.
BVS ID reads the inverted TI bit, places the next partial data in the input buffer and inverts the TO bit.
The PLC reads the inverted TO bit and accepts the next partial data. If additional partial data must be
transferred, continue with 5, otherwise with 8.
The PLC resets the
Job bit and the TI bit if necessary.
BVS ID reads the reset Job bit, withdraws the Job End bit, Job Start bit, and the TO bit if necessary and
is ready for the next command.
