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.

The μR series are the compact industrial recorders with the recording widths of 100 mm (μR10000) and 180 mm (μR20000). Measured data can be saved to an SD memory card while recording on chart paper.
