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) Serial Control of Outputs
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.
b) Diagnosis Only
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'.
