Time Chart of Multiplex Reception
Explanation of operation:
The operation if multiplexed data are received when executing the MRCV instruction.
MCU detects the completion of data reception.
The reception done flag X0(X2) is taken in the CPU by the I/O refresh operation, however, new data
is received with MCU by then.
Makes the reception done flag X0(X2) be the execution condition, and the received data is copied in
the operation memory using F161 (MRCV).
Once copying data completes, the PLC data reception done flag X1(X3) turns on.
After completing the execution of the MRCV instruction, the reception done flag remains to be on as
the data that has been completed to be received is left in MCU.
As the MCU reception done flag is taken in by the I/O refresh operation of the CPU, X0(X2) remains
to be on.
Also the PLC data reception done flag X1(X3) turns off by the I/O refresh operation.
Makes the reception done flag X0(X2) be the execution condition, and the received data is copied in
the operation memory using F161 (MRCV).
Once copying data completes, the PLC data reception done flag X1(X3) turns on.
After completing the execution of the MRCV instruction, the MCU reception done flag turns off as the
reception done data disappears.
As the MCU reception done flag is taken in by the I/O refresh operation of the CPU, X0(X2) turns off.
Also the PLC data reception done flag X1(X3) turns off by the I/O refresh operation.
