Measured data received by the PLC differs from what's displayed on the μR.

Q:
I'm trying to read µR measured data from a PLC using a µR series RS-422A/485 communication interface option (/C3) model. I can receive the data in binary format with the FD command, but measured data received by the PLC is completely different from the µR display. Since a response comes back, communication is established with the PLC. Also, I'm specifying the correct channel number in the FD command. What could be the problem?

A:
When receiving binary data through serial communication, you must set a data length of 8 bits as a communication condition. 7 bit will not result in correct data.
