Notes:
The symbol character (0, 1, 3, or 4) must be placed in the first position of the address string. The address number follows the symbol character.
The symbol character does not behave as a number. For example, 400100 and 40100 designate the same memory area (holding register 100).
The memory areas listed above are provided for general purposes. The actual available memory area and range of each area should be checked using the manual for the connected device. The ‘Read’/’Write’ columns show the MODBUS function codes used in this communication driver.
Code 16 is issued for writing double words or when the recipe write function is activated. When writing single words, code 6 is used.
