Data transfer via communication ports

"Reception done" flag

When the end code is received, the "reception done" flag turns to TRUE. Reception of any further data is

prohibited. F159_MTRN (see page 741) turns the "reception done" flag to FALSE.

The "reception done" flag can be evaluated using the IsReceptionDone (see page 760) function. Or use the

system variable sys_bIsComPort1ReceptionDone, sys_bIsComPort2ReceptionDone, or

sys_bIsToolPortReceptionDone, depending on the port. The end of reception can also be determined by

time-out using the IsReceptionDoneByTimeOut (see page 761) function or by checking the contents of the

receive buffer.

The status of the "reception done" flag may change while a scan is being carried out. For example, if the flag is

used more than once as an input condition, different statuses may exist within one scan. To ensure proper

execution of the program, the status of the special internal relay should be copied to a variable at the beginning

of the program.
