9.5.1 Reading the Extended Status
To read the extended status of a slave, write the station number to the
diagnostic status station select register, register 3828 in the M1 file. The
scanner then retrieves the diagnostics for that slave. If the scanner
successfully gets the diagnostics, it puts them in registers 3829-3950 and sets
the high byte of the diagnostic status station select register to 80h. If there is
an error in getting the extended diagnostics, the scanner sets the high byte of
the diagnostic status station select register to 40h.
9.6
DP Master Error Information Table
The area in the M1 file from 3700 to 3827 contains error information about
each slave, one register per station number. This table can be used in
conjunction with the slave status table (4000-4007) or the slave error table
(4020-4027) to determine the cause of the error.
The scanner sets various values in the high byte to indicate the cause of any
problems with the slave. Some errors occur during parameterizing the slave,
others occur at runtime. If there are multiple errors, only the last one is
shown. The host acknowledges these errors by clearing the register.
