      How can I read and display a character string from a Modbus slave that is saved as two chars per word and held as integers ?

        You can use CHAR[n] on column B of your csv, ‘n’ is the number of chars (n chars will use n/2 registers). For example CHAR[10] will read 5 consecutive registers and will represent a string of up to 10 characters. If you find your PLC to swap characters on registers you can set ‘str_byte_swap’ to true in order to get the correct string.
