3.9 Result Of Counter Registers
The Result of Counter registers are 16-bit registers that allow
you to read the current counter value. The counter contents
are transferred to the transfer memory area of the module
and are then available to the user. Reading a result of counter
register does not affect the counter operation.
While using the standard software, the "BEF" parameter of
FBI59 will be "LE" in order to read the result of counter
registers. This parameter is described in detail in Chapter 4
of this manual.
