Kohler MODBUS logging. Registers Map


The data can be automatically logged 24/7 into a database, CSV files, or Excel spreadsheets using the Advanced Serial Data Logger (for MODBUS RTU) or Advanced TCP/IP Data Logger (for MODBUS TCP) software. These tools provide continuous and reliable Kohler logging and record.
