P0879 is set to indicate whether it involves a zero mark or an equiv-
alent zero mark (BERO). The equivalent zero mark must be parame-
terized at input terminal I0.x.

Only one value can be fetched at a time. Only one value can be fetched at a time.
Reason: Only one shared status word Gx_XIST2 is available for
reading the values.
