If function is 16 - from '''1''' to '''123''' (first register + registry value can not go out of range), Registry values separated by commas without spaces. Example.: '''1,2,3,654,21,789'''. There has to be as many values, as specified number of registers, and each value must be between '''0''' and '''65535'''. If number of registries is 0, there should be '''no registry values'''

When the value climbs over 65535 the counter resets and the value held by the first register increases by '''1'''. So one way to interpret the results would be to multiply the value in the first register by '''2¹⁶''' and add it to the value of the second register. In this example: '''9 * 65536 + 3502 = 593326s''' or '''6 days 20 hours 48 minutes and 46 seconds.'''
