Two wire ction QJ71C24N RS485 QJ71C24N programming and setting conditions:
CH2 (A) RS485 communication: send command to HB050, accept 8 bytes of data for 3031323334353637 38.
B) H136 is set to 0, and the word is accepted as a unit. H144 is 5, accept the end of the 5 sub.
C) first with H148 set to 1, clear the receiving area, and so on H148 into 0, cleared, delay 100ms, and then start

1) is not normal, you can the module of the 1C2H cache address to write 1, to prevent the receiving program to send.
About 2) you may have set the length of the data.
About 3) may be set by you and your actual data length data received by different length.
4) 148H which is written in the 1 module OS area. So the next time the data received will not exist before

Thank you for your reply！
1) the 1C2H cache of the module is a system area that is not used. In the program, through the TO command assignment? Will not cause an exception module? Is there a detailed explanation of the 1C2H?
2) how long does it take to clear the reception area with H148 set to 1?
3) after power off, or Stop switch to RUN, the OS area will be cleared?
YnF initialization

1) with the TO command can be, not unusual. Instructions in the manual, manual number 80006
2) how long is not clear.
3) the power to restart the OS will not be clear. No signal for factory initialization is set.
4) time is not clear.
5) the wait time for this cache setting is used when the module uses the MC protocol.
6) XA, XB will not always set ON.
7) receive
