The bits in station status byte 1 are:
high byte = 07h (error in diagnostic status byte #1 during diagnostic read)
The value in the low byte depends on the value returned by the slave in the
first station status byte when the master reads diagnostics while online. Mask
the value with 0F7h and any bits that are set should not be set. The bits in
station status 1 are shown in the above table.
high byte = 06h (error in diagnostic status byte #2 during configure)
The value in the low byte depends on the value returned by the slave in the
second station status byte when the master reads diagnostics during
configuration. Mask the value with 080h and any bits that are set in the result
should not be set. Mask the value in the low byte with 04h and bit 2 should be
set.
