Hello, I am trying to log the voltage current and power data from the m850 power meter via rs485 with a dt80 logger. I found some code examples and put the following code together. I have linked the manual with the modbus register list. Can any one say if this should work? Any Help most welcome https://www.hobut.co.uk/wp-content/uploads/2022/02/M850-LTHN-RS-PO-User-manual-rev-4-SP-compressed-10-10-14.pdf Begin’M850PM’ ‘================================================= ‘ ‘ DT80 code to read a Hobut M850 power meter ‘ via RS485 Modbus ‘ ‘ 1 Phase 2 wire configuration. ‘ Reads all Modbus type 3 registers. ‘ ‘ This code used block reads of Modbus registers ‘ - Block reads are in groups of 10 for readability ‘ - Block reading reduces reading times of registers ‘ -Channel Variables ‘ ----- 4CV = Voltage ‘ ----- 7CV = Current ‘ ----- 10CV = Watts ‘================================================= ‘ Profile settings for Modbus Master ‘ Note: Check port settings and set profile to match.
