Master Unit
Error Check Bit
If there are errors in more than one Slave, or multiple terminators have been set,
data for the Units can be accessed in order by turning these bits ON (after the
data is read, the bit automatically turns OFF). Bits A00500 to A00507 corre-
spond to Masters #0 to #7.
Remote I/O Error Flag
This flag indicates that an error has occurred in a Remote I/O Slave Unit, an I/O
Link Unit, or a Remote Terminal. It also turns ON where there is more than one
terminator set.
Multiple terminators are detected as follows:
