A definite distinction between open load and short to ground is guaranteed by design.
The standard way of obtaining diagnostic information is as follows:
Clock in serial information into SI pin and wait approximately 150 μs to allow the outputs to-
settle. Clock in the identical serial information once again - during this process the data com-
ing out at SO contains the bit combinations representing the diagnosis conditions as described
in figure 1.
By means of the control byte it is possible either to:
a) control the eight outputs according to the data byte, as well as being able to read the
diagnostic information
or b) purely get diagnostic information without changing the state of the outputs.
a) Serial Control of Outputs
HHHHHHHH LHLHHLLL
Control Byte
Control byte is set to FFhex: Data byte will be accepted. The outputs will be switched ON or
OFF according to the information of the data byte and the parallel inputs (Channel 1 to 4 be-
cause of AND operation).
All other control words except the one for 'Diagnosis Only = 00hex' will also be accepted as a
valid control word and the data will be accepted.
Example: HLLHLHLH DDDDDDDD: Outputs will switch according to the data bits.
Data Byte
: Serial input information
b) Diagnosis Only
LLLLLLLL XXXXXXXX
Control Byte
Control byte is set to 00hex: Data byte will be ignored. Diagnostic information can be read out
at any time with no change of the switching conditions. Only 00hex means 'Diagnosis Only'.
Data Byte
: Serial input information
