5-24 Configuration and Programming

Device Fault bit. If the Communications Attempted bit is 1, the
Enabled Device Fault bit is valid.

RIO Baud Rate Status

Word 2, bits 0 to 1 display the RIO communication baud rate you have
set the scanner to via its DIP switch. Writing to word 2 does not
change the scanner baud rate.

As illustrated by the table below, bit 0 = SW1 and bit 1 = SW2.

Logical Device Starting Address Status

Word 8 provides status/feedback of the logical device starting
addresses you configured in word 1 of the G file (primary/normal
logical devices). Writing to M1 file word 8 does not alter the contents
of the G file.
