Applies to RTU Master & Slave
This feature will allow the device operating as either RTU Master or Slave, to ignore garbage data
appended to any valid RTU message. The RTU Master will compare the received bytes with
expected number of bytes. The expected number of bytes in the Master is calculated while the
COMMREQ information is processed to create the query.
The RTU Slave will determine the message length by examining the Function code in the query
message during reception. The slave will determine the expected query message length after
receiving at least two characters and no more than seven characters of the message.
Applies to RTU Master Only
If the Master receives the incomplete frame and if the CRC is invalid then the error code 0607H
would be returned as a status.
The frame transmitting sequence from the master is modified so as to handle the broken frames.
This enhancement in transmit sequence will add robustness to the system.
