(10) BFM #29 Error status
Error status in the FX-1HC can be checked by reading the contents of b0 to b7 of BFM #29 to auxiliary
relays of the PC.

Error status

Set when any of b1 to b7 is ON.
Set when the value of the ring length is written incorrectly (other than K2 to K65,536).
Set when the preset value is written incorrectly.
Set when the compare value is written incorrectly.
Set when the current value is written incorrectly.
Set when the counter overflows the upper limit.
Set when the counter overflows the lower limit.

When the upper or lower limit is exceeded on a 32-
bit counter.

When value 

≥

 ring length in 16-bit counter mode.

Set when the FROM/TO command is used incorrectly.

Undefined

There error flags can be reset by b8 of BFM #4.
(11) Model identification code number BFM #30
The identification number for a Special Function Block is read by using the FROM command.
The identification number for the FX-1HC unit is K4010.
By reading this identification number, the user may create built-in checking routines to check whether the
physical position of the FX-1HC matches to that of the software.
