- The default address of the instrument is 001, baud rate 9600, n without checksum, 8 bits of data, 1 bit of stop bit, default co-instrument 0
- If the battery supply and the two-wire system do not support the 485 functions, the battery can be removed and the 24V supply can be confirmed as normal.
- The instrument communication is based on the MODBUS RTU protocol, note that the instrument can read up to 14 words in a row.
- Communication register address needs to be offset by 1 bit if using PLC, and other software devices, e.g.: 0768, then use 0769.
- If the accumulation (BCD code format) in the field protocol 0 cannot be resolved, it can be debugged as protocol 1, and all data format in protocol 1 is floating-point, refer to MODBUS protocol (D2 type).
- D4 type on a protocol with D2 protocol 1.
