*1 To RESET the special function block, set both parameters (6&7) to “reset module”.
While processing a RESET command, no other parameter will be accepted by the
special function block.
As mentioned in the FX
2N
-4AD users guide the EEPROM access takes 300ms. So it is
not possible to RESET the special function block to defaults and set the BFMs 0 to 24 to
a value different to the default value with the same parameter data block.
However, it is possible to send a parameter block to RESET any special function block
that supports the RESET function and afterwards to send a second parameter block to
set the module/s to the desired parameter values.
*2 In this case the default value of the GSD file (high speed) differs from the hardware
default value (normal speed).
*3 The changes of BFM # 0 are written to EEPROM memory. Keep a delay of 300ms
between setting the input range and other write accesses to the EEPROM.
