• Values are read with FC03 and are 32-bit floating-point numbers (two registers, most significant register first), as a user report on the Node-RED forum confirms. Addresses are the register addresses of the register list.
• The register list does not give units; the units shown are those of the quantities (V, A, Hz, W, var, VA).
• Factory settings: address 1, 9600 baud, 8 data bits, 1 stop bit; the manufacturer's list shows a check bit and third-party guides give even parity.
• Writes: Meter ID, baud rate, combined code and cycle time with FC06, S0 output rate with FC16.
• Only the registers listed in the manufacturer's register list are in this map.
